Recessed Lighting Buying Guide

Recessed lights, also known as downlights or can lights, are a type of lighting fixture installed into the ceiling or wall. They are designed to sit flush with the surface for a sleek and polished finish. The housing and electrical wiring components are hidden, and the bulb appears to glow from within the opening. Recessed light bulbs are energy efficient and last longer than ordinary bulbs.

This lighting is a great option for many rooms in your home, and there are many options to consider when choosing the best recessed lights for you, including size, trim and bulb temperature. This explains the types of recessed lighting.

Where to Place Recessed Lighting

In new construction, recessed lighting is usually installed between ceiling joists, but you can retrofit recessed lighting almost anywhere in your home.

If your ceiling is insulated, the recessed light fixtures must be IC housing rated, meaning they are approved for use near insulation.
Avoid recessed lighting in concrete ceilings or in ceilings with detailed plasterwork or moulding. Choose a chandelier instead.
Place recessed lights about 3-feet away from the wall to avoid creating shadows that make your ceilings look lower.
When spacing recessed lights, use this general rule of thumb: divide the height of the ceiling by two to get the distance the lights should be from one another. For example, an 8-foot tall ceiling should have recessed lights spaced 4-feet apart.
Use recessed lights to illuminate focal points such as kitchen bars, bookshelves, paintings, statues and fireplaces.
For task lighting, install recessed lighting directly overhead. Examples of task lighting include lighting for reading areas, stovetops and sinks.
Install recessed lights under kitchen cabinets to have focused light on counters.

Recessed Lighting Trims

Recessed light trims refer to the part of the fixture that is visible from the outside. There are a variety of different trims available.

Baffle trim

The ridges on baffle trim recessed lights are designed to reduce glare from the recessed light bulbs.
These are great for creating a softer glow and a reducing eye strain.
This trim is recommended for the living room, entryways and foyers.

Reflector trim

The polished finish on reflector trim recessed lights amplify the light beam.
These lights are brighter and more vibrant.
This trim is recommended for kitchens and rooms with higher ceilings.

Gimbal trim

Gimbal trim recessed lights are designed to pivot and turn to offer directional light.
They direct downlight exactly where you need it.
This trim is ideal for accent walls and on sloped ceilings.

Wall wash trim

Like gimbal trim, wall wash recessed lights tilt and rotate, but these offer a greater range of motion.
They offer directional light and are great for adding emphasis or highlighting a task.
This trim is great highlighting artwork on gallery and display walls.

Shower trim

Shower trim recessed lights, also known as a ceiling mount trim, are wet location rated and resistant to moisture and corrosion.
They feature a clean and understated design to blend in with your bathroom.
This trim is specifically designed for installation above the bathtub and in shower stalls.

Recessed Lighting Sizes

There is a range of recessed light sizes. To determine the size, measure the diameter of the cut-out opening in inches, not including the trim.

Choose one that will accommodate the height of your ceiling or the size of your wall.

4-inch and 5-inch fixtures are great in kitchens for providing overhead countertop lighting.
6-inch fixtures are most common for general lighting purposes.
7- to 9-inch fixtures will create a wider wash of light.

Recessing Lighting Color and Temperature

Most recessed lighting fixtures come in three different color temperatures:

Soft: comfortable light with a warm glow
Bright: refreshing light with a cool glow
Daylight: designed to mimic natural light

With custom installations, you can have tunable lighting that changes color or temperature as desired. Adjust the lights right from your smart phone or other device.

Selectable lighting gives you the option to preset multiple temperatures before installation.

Recessed Lighting by Room

Recessed lighting can be a great addition to any room. The most popular rooms to install recessed lighting are the kitchen, bathroom and living room. This type of lighting is also commonly used in outdoor living spaces.

Kitchen recessed lighting options will vary according to the size of your space, but a reflector trim is highly recommended. Choose lights that are 4-inches or 5-inches in diameter to provide enough concentrated light for meal prep and cleanup.
The best bathroom recessed lighting options are waterproof and designed for wet or moist locations. They will resist corrosion and are less likely to short circuit over time.
Living room recessed lighting fixtures serve a variety of purposes. If you’re looking to display artwork or accent pieces, consider wall wash trim options. If your ceilings are sloped, choose lights with a sloped trim to accommodate the space.
Outdoor recessed lighting is designed to stand up against the outdoor elements, including rain, storms and extreme temperatures. These are also available in multiple sizes and trims and with a whole host of unique features.

LED Recessed Lighting

While standard recessed lights are extremely energy efficient, integrated LED recessed lighting can operate for years before a bulb change is required.

Integrated LED

The LED bulbs in integrated LED lighting are built into the fixture.
This all-in-one unit connects directly with the main lines or tracks.
Professional installation is recommended for this kind of recessed lighting.

LED retrofit

An LED retrofit is used to add LED bulbs to your existing recessed lighting fixture.
These kits convert your light cans to ones that are compatible with modern LED lights.
DIY installation is simple, and instructions are easy to follow.

Tip: If you plan to add LED bulbs to fixtures on a dimmer, you will need to replace the dimmer switch, and make sure to select dimmable LEDs.

Recessed lighting can offer subtle, functional lighting that blends seamlessly into your decor, or it can help create striking focal points in your home, depending on your needs.

How To Create The Atmosphere You Want In Your Home By Using Lighting

The lighting of any space defines the atmosphere that is created. Even in your home, it is one of the most essential components that decide the ambiance of the space. Bright lights help keep you fresh and awake while dimmer lights provide a more soothing environment. Subsequently, manipulating your home’s lighting setup can completely transform the aura and mood in your house. Here are some tips as to how you can create the atmosphere you want in your home by modifying the lighting.

1. Create A Lighting Plan

Whether you’re redoing the lighting of a room or simply starting from scratch, it’s a good idea to first create a lighting plan that covers every aspect. Your plan should cover the very basics for the lighting setup of your room. For each room, you need to consider the activities that need to take place in that particular room or space and choose the lights accordingly. For example, your bedroom should have a comfortable lighting setup, and shouldn’t consist of harsh overhead lights. You also need to consider the architectural features of a room that you want to define. Make sure that you consider the style, scale, intensity, and color temperature of the lights you select.

Keeping these factors in mind, you’ll be able to come up with a rough sketch of how you want to design your lighting. Early planning will make sure there’s no clash between the lights you set up and the room’s color scheme.

2. Layering Lights

You should consider a multilayer lighting approach to make the most of every inch of your room and give it more ambiance. You can use different types and styles of lights to give the room a more aesthetic aura. Whether you choose to combine these different light sources from a single point, like the ceiling, or from different places in the room like the walls, stairs, and even the floor, make sure that the light illuminates every part of the room well. Though, when you use a combination of lights, the illumination is much more enhanced. By using suspended luminaires in the form of a cluster, even a large room will look cozy. Similarly, if you want to make your room look taller, you can use a combination of spotlights.

3. Ensure the Lighting Is Practical

The functionality of your home’s lighting should be your first priority, aesthetics come second. Make sure whatever combination you choose is practical, keeping in mind the requirements of each room.

Your kitchen should be the brightest place in your home since cooking requires bright illumination. To achieve the best kitchen lighting, you can combine bright downlights, accent, and recess lighting, which works best above stovetops. Sunlight is also a great source of natural illumination and should be present in your home in a sufficient amount. You can make use of window shutters to control the amount of sunlight entering your rooms. You’ll easily be able to dim the lights according to your mood and weather changes. To ease your reading habits, directional lighting can be installed in your study rooms. Another great idea for practical lighting is using dimmers in your bedrooms so that you can easily change the atmosphere and warmth of your rooms.

4. Choose Carefully

When choosing the LED lights or bulbs for your lighting fixtures and lamps, you need to pay more attention to the energy efficiency and color temperatures. The color temperature of the bulbs will decide the basic atmosphere created. A low light color temperature will give a more warm look, whereas a higher light temperature will provide a cool, sky-like illumination. Warm color temperature is considered the best option for indoor home lighting. The second thing you will need to consider is the energy efficiency of the bulbs. Be mindful that LED lighting is much more energy-efficient than incandescent bulbs and is majorly considered the better alternative.

5. Utilize Accent Or Spotlights

If you want to create the effect of having a large space, you can accentuate certain spots to make your rooms look bigger. By accentuating mirrors on the wall, your room will not only look bigger but also get a sophisticated aesthetic. You can also highlight certain architectural elements or fancy furniture by using wall-mounted accent lights.

6. Be Consistent

Make sure you keep the theme, color scheme, and lighting of your home well-suited with each other. Your lighting should be consistent, huge variations in light intensity or style shouldn’t be seen in every other room of your home. Although neutral and dark combinations are suggested, make sure the difference doesn’t cause uneasiness.

Your home’s lighting is as important as any other essential. In addition to providing the necessary illumination for your day-to-day tasks, it also defines the type of atmosphere created in your home. By using a combination of accent lighting, spotlights, and other fixtures, you’ll be able to achieve that cozy, aesthetic, and warm ambiance you desire.

LED vs. HID

LED and HID lamps are two of the many lighting technologies that are available today. Knowing the difference between HID and LED can help you make an educated decision on what’s best for your application and budget.

HID and LED Comparisons
Left to right: differences in output and color rendition of mercury-vapor, metal-halide, high-pressure sodium, and LED high-bay lights for use in typical HID applications
HID (High Intensity Discharge):
HID lamps consist of a ballast and a quartz tube that contains gas, metal salts, and two tungsten electrodes. The ballast controls the voltage and current necessary to operate the lamp.

LED vs HID – An HID fixture and an HID replacement bulb
An HID fixture and a metal-halide HID replacement bulb
An electric arc passes from one electrode to the other through a gas (most commonly mercury, metal halide, or sodium). The arc heats metal salts and vaporizes them—creating a plasma—which increases light output created by the arc and increases efficiency.

Types of HID Lamps
Mercury-Vapor:
This type of lamp creates an electric arc through vaporized mercury that produces a bluish-green light. An outer bulb envelope insulates the bulb and protects against ultraviolet radiation. Mercury-vapor lamps are the oldest type of HID lighting and are being phased out because of the increased efficiency and better color rendition of metal-halide lights.

Metal-Halide:
Much like mercury-vapor lamps, metal halides have an electric arc that is created through vaporized mercury. However, metal halides (such as sodium, indium, and thallium) are added to increase efficiency and improve the light’s color-rendering index (CRI). An outer bulb envelope insulates the bulb and protects against ultraviolet radiation.

High-Pressure Sodium:
This type of HID lamp uses mercury vapors and sodium to ignite an electric arc, which produces a gold-colored light that is used mostly in parking garages.

Considerations:
HID bulbs are used for many applications, including warehouses, parking garages, outdoor stadiums, street lights, and headlights.
They produce a substantial amount of ultraviolet (UV) radiation that can be damaging to skin, eyes, and fabric.
Due to the large amount of energy that passes through it, the ballast necessary for creating the arc often wears out quickly.
HID bulbs and fixtures can last up to 20,000 hours but will often start to lose color and brightness long before that. To protect the ballasts, it is recommended that bulbs be replaced when they’ve reached 70 percent of their life span.
They last at least three times longer and are three times brighter than halogen bulbs, but their life spans are three times shorter than LED bulbs.
HID bulbs are fragile and contain mercury. They should be recycled, and bulb contents should be sealed if they are broken.
These lights can take anywhere from several seconds up to 10 minutes before they reach full brightness, and they need time to cool after being switched off before they can be turned on again.
They pose a risk for explosions and fires and can reach temperatures that make them unsafe to touch.
Shop Super Bright LEDs for solutions to retrofit old HID fixtures with more efficient, higher-performing LED bulbs.

Energy Consumed at Equivalent Light Output – LED vs HID
LED (Light Emitting Diodes):
LEDs produce the longest-lasting, most energy-efficient lighting available today. A semiconductor rich in electrons and a semiconductor rich in holes are used to create an LED.

LED Wall Pack and LED Corn Bulb – LED vs HID
LED wall pack and LED corn bulb
Passing a current through the junction of these two materials combines the electrons with the holes and produces photons, which is the light that you see.

Considerations:
LEDs run much cooler than HID bulbs and don’t require high running temperatures to work properly, which greatly increases their longevity and enables them to function in cold temperatures.
Unless an LED light is specifically infrared (IR) or ultraviolet (UV), it produces little to no IR or UV radiation, which can be damaging to skin, eyes, and fabrics.
They can last up to 50,000 hours—three times longer than HID bulbs and fixtures.
Power consumption is the lowest compared to all other lighting technologies—80 percent less than HID bulbs.
LED lights contain no mercury, harmful gasses, or toxins.
Many of these bulbs are shatterproof and shock resistant.
They illuminate instantly unlike HID bulbs that can take several minutes to reach full brightness.
LED lights require higher initial investment but are the best value due to energy savings and longer life spans.
They are available in many different colors and variations of white.
Because of their low power consumption, LED lights are great alternative lighting solutions for solar-powered systems.
To remove the hassle of bulb replacement, Super Bright LEDs also offers many fixtures with LEDs integrated into the fixture. Shop thousands of LED lighting solutions at OmaiLighting.com now

Living with light

Light affects your mood and well-being, often without you having to think too much about it. Imagine how much nicer it is when the sun is shining, or how cozy it feels when you’re sitting in front of a warm fire.

Lighting in your home

The light in your home affects you. All rooms need lighting, but to be functional and comfortable, you usually need more than just a ceiling light. Light creates security, and contributes to a cozy atmosphere and helps you to do what you want, when you want.

Mixing diffused and direct lighting

Rooms need a mixture of diffused and directed light to be both functional and pleasant. Place your lamps at different heights to create differentiated light and shade. To know where in the room you need diffused and directed light, just ask what do I do in this room, and where do I do it?

Functional lighting

Make it easier to carry out your pursuits, easier to focus no matter what you do or when. Focus on anything from threading a thread to working at your desk or kitchen counter. Functional lighting illuminates a limited area with a concentrated, directed light.

Mood lighting

Create a soft, inviting feel in your room. A good way is to place smaller lamps to spread a diffused light in different places in the room. Often lamps where the lamp shade is made of fabric, paper or glass diffuse light as the light can be filtered through the screen.

General living room lighting

Shining a soft light gives you a good overview of the whole room, and that’s important when performing activities that require light throughout the room. Set up a ceiling light that spreads diffused light, or use ceiling spotlights with multiple lamps.

Integrated lighting in your home

Enjoy integrated lighting in cabinets, on your shelves, in wardrobes and in your kitchen. You can display what you have, find things easier and get work done with the right light in your home.

5 things to think about before buying LED bulbs

If you haven’t switched to LED bulbs, now is the time. The reasons why are compelling. For starters, LED bulbs last much longer than incandescent bulbs, and they put out the same amount of light using significantly less energy. That’s great for the environment, and it can save you lots of money in the long-term on your electricity bill.

If you’re smart home-inclined, LEDs open the door to all sorts of interesting and worthwhile features, including bulbs that change colors and bulbs that sync with your security system or voice assistant of choice. Besides, many incandescent bulbs — including the 100-watt incandescent — are being phased out, so you’ll need to make the switch eventually, anyway.

Buying the right LED is very different from buying incandescent bulbs. Before you go shopping, though, there are some things you need to know.

Lumens, not watts

Forget what you know about incandescents — your watts are no good here.

When shopping for bulbs, you’re probably accustomed to looking for watts as an indication of how bright the bulb will be. The brightness of LEDs, however, is determined a little differently.

Contrary to common belief, wattage isn’t an indication of brightness, but a measurement of how much energy the bulb draws. For incandescents, there is an accepted correlation between the watts drawn and the brightness produced, but for LEDs, watts aren’t a great predictor of how bright the bulb will be. (The point, after all, is that they draw less energy.)

For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts.

But don’t bother doing the math — there isn’t a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.

The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs. For reference, here’s a chart that shows the watt-lumen conversion for incandescents and LEDs.

As you can see in the chart above, an incandescent can draw up to five times as many watts for the same number of lumens. Get a sense of the brightness (in lumens) you need before heading to the store, and throw away your affinity for watts.

Choosing the right color LED

Incandescent bulbs typically put out a warm, yellowish hue, but LEDs come in a range of colors.

As shown off by Philips Hue, LED bulbs are capable of displaying an impressive color range, from purple to red, to a spectrum of whites and yellows. For the home, however, you’re likely looking for something similar to the light that incandescents produce.

The two most popular colors available for LEDs are soft white (also called warm white) and bright white (also called daylight). Not confusing at all, right?

Soft white and warm white will produce a yellow, candle-like glow, close to incandescents, while bulbs labeled as bright white or daylight will produce a whiter light, closer to daylight and similar to what you see in offices and retail stores.

If you want to get technical, the color of light on the white light spectrum is called color temperature, and it’s measured on the Kelvin scale. The lower the number, the warmer (yellower) the light. Your typical, soft white incandescent is somewhere between 2,700 and 3,500K, so if that’s the color you’re going for, look for that range while shopping for LED bulbs. Want something daylight toned? Look for bulbs rated at 5,000K or higher.

You’ll pay more for an LED bulb (but you’ll save in the long run)

LED bulbs are like hybrid cars: More expensive upfront, but cheaper to operate.

It used to be that you could grab an incandescent bulb at the hardware store for a buck or so. Then, LEDs came along — most of them costing a lot more. Thankfully, several years of development and competition have brought prices down to the point where you’ll find plenty of LED options in the light bulb aisle available for $5 or less.

But the dollars and cents don’t stop there. You need to factor in the cost of using the bulb — and the great thing about LEDs is that using them doesn’t cost very much at all. For instance, a traditional 60-watt incandescent light bulb will add about $7 to your energy bill each year if you use it, on average, for 3 hours a day. A 60W-replacement LED that puts out the same amount of light will draw as little as 8 watts, and only add about a buck to your energy bill over that same year-long span.

In other words, even if the LED costs $5 and the incandescent is a freebie that you found rolling around in a drawer somewhere, the LED is still the less expensive option after less than a year of use. In the meantime, you’ll enjoy less heat production, longer bulb life and even the option of controlling them with your smartphone — and it won’t burn out after a year, either.

Watch out for non-dimmable LEDs

Because of their circuitry, LEDs are not always compatible with traditional dimming switches. In some cases, the switch must be replaced. Other times, you’ll pay a little more for a compatible LED.

Most of the existing dimmers in homes today were likely designed to work with incandescents. Dimmers like those work by cutting off the amount of electricity sent to the bulb in rapid-fire succession, faster than the eye can detect. LEDs draw a lot less energy, so they don’t always work well with dimmers like that (here’s a handy guide that goes a little deeper into the reasons why).

The first thing to do if you’re buying LEDs that you want to use with a dimmer switch is to make sure that you buy bulbs that are, in fact, dimmable. Most manufacturers offer non-dimmable LED bulbs with no on-board dimming hardware whatsoever, and while those are fine if you want to save a buck or two on a bulb intended for a non-dimmable fixture, they’re the last thing you want if you like the lights dimmed down low.

My second recommendation? Start with a single bulb from a major manufacturer and hang onto the receipt. Try it out with the dimmers in your home, and if it works, feel free to buy as many as you need. If not, most major retailers will be happy to let you return the bulb and exchange it for something else. At some point, you might also consider upgrading your dimmers to newer models designed to work with LEDs. Big names like Lutron and Leviton are your best bet there.

One last point: If dimming is truly important in your home, then you should really consider smart bulbs. Most use their own, built-in mechanisms to handle dimming, so you don’t need a dimmer switch at all. Dimming mechanisms like those are great because they won’t flicker or buzz, and you’ll usually be able to sync things up with a voice assistant like Siri or Alexa, which opens the door to commands like, “set the lights to 20%.”

Not all light fixtures should use LEDs

Knowing where it’s OK to place an LED will ensure that the bulb won’t fizzle ahead of its time.

You probably know that LED bulbs run a lot cooler than their incandescent cousins, but that doesn’t mean they don’t produce heat. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a long life.

And therein lies the problem: The bulb needs a way to dissipate the heat. If an LED bulb is placed in an enclosed housing, the heat won’t have anywhere to go, sending it right back to the bulb and sentencing it to a slow and painful death. Remember, LED bulbs are electronic devices — just like with your phone or your laptop, it isn’t good to let them overheat.

That’s why it’s fine to stick with incandescent, fluorescent and halogen bulbs for enclosed fixtures. LEDs will work, too, but in some cases, the heat build-up inside the fixture will reduce the bulb’s lifespan.

Guide to Light Fittings, Caps and Bases

What Are the Different Types of Light Bulb Fittings, Caps and Bases?

The part of the lamp or light bulb that connects into the light fitting is generally known either as the “cap” or “base”.

Caps provide the electrical contact to conduct electricity to the light bulb but it also helps to secure the light bulb into its fitting.

There are a vast variety of caps and bases that exist in order to help make sure that only the correct type of lamp is used in any given fitting. This section shows many of the most popular fittings.

Bayonet Cap

BC-B22d Cap

Diameter: 22mm
Diameter (Pin to Pin): 27mm
Height: 26mm

With its familiar “push and twist” action, the “bayonet cap” (also known as BC or B22d cap) is used on most regular light bulbs. It is 22mm in diameter and with two locating lugs

SBC-B15d Cap

Diameter: 15mm
Diameter (Pin to Pin): 17mm
Height: 26mm

The “small bayonet cap” (SBC or B15d) is very similar but only 15mm across.

Although generally used for mains voltage lamps, the SBC fitting can also be found in a very small number of specialist low voltage halogen lamps.

There are also many other bayonet cap variants including the 3-pin BC B22d-3 sometimes used on Fireglow lamps but perhaps more commonly on High-pressure mercury lamps for industrial applications. The BY22d is used on some low-pressure sodium (SOX) lamps.

Edison Screw Cap

Named after the pioneering inventor Thomas Edison, the Edison Screw cap or “ES” lamp fitting is used worldwide in a vast range of applications.

ES-E27 Cap

Diameter: 27mm
Height: 26mm

The most popular ES or E27 fitting is 27mm diameter and is widely used in UK and Europe. This cap is the standard 27mm diameter screw cap for UK 240V light bulbs – not to be confused with E26, which is a 26mm size and is designed for the 120V US market.

SES-E14 Cap

Diameter: 14mm
Height: 26mm

The SES or “Small Edison Screw” cap is often used for smaller decorative fittings, chandeliers, and appliance light bulbs – It has a diameter of 14mm and is predominantly used in the UK and Europe.

There are also many size variations, mainly for use in specialist fittings. The MES-E10 fitting is sometimes used in large chandeliers containing perhaps dozens of small lamps.

Designation	Diameter	Name	Abbreviation
E5	5mm	Lilliput Edison Screw	LES
E10	10mm	Miniature Edison Screw	MES
E12	12mm	Candelabra Edison Screw	CES
E14	14mm	Small Edison Screw	SES
E27	27mm	Edison Screw	ES
E40	40mm	Giant Edison Screw	GES

Capsule Lamps

Miniature halogen capsule light bulbs are generally used in integrated fittings and appliances, such as cooker hoods and kitchen cabinet lights.

Capsule light bulbs can be identified by their miniature size and they all have 2-pins extruding out of the base of the capsule. The model of the capsule is designated by the measurement in mm between these two pins.

The different distances between the pins prevent the wrong type of capsule light bulb being inserted into the wrong fitting – such as a 12V G4 capsule being inserted into a 240V G9 light fitting.

G9 Base

Distance Pin (Centre) to Pin (Centre): 9mm

The G9 is specifically used for 240V capsule light bulbs. The light bulb can be identified by measuring the distance between the centre points of the pins. The distance of a G9 measures 9mm.

G4 Base

Distance Pin (Centre) to Pin (Centre): 4mm

The G4 is specifically used for 12V capsule light bulbs. These capsules require a 12V transformer or driver to operate – this is usually built into the fitting. The capsule can be identified by measuring the distance between the centre points of the pins. The distance of a G4 measures 4mm.

GY6.35 Base

Distance Pin (Centre) to Pin (Centre): 6.35mm

The GY6.35 is specifically used for 12V/24V capsule light bulbs. These capsules require a 12V transformer or driver to operate – this is usually built into the fitting. These capsules are often used for task lighting. The capsule can be identified by measuring the distance between the centre points of the pins. The distance of a GY6.35 measures 6.35mm.

LED Capsule Bulbs are now also available as an energy-efficient alternative to halogen light bulbs. The fitments on LED capsules are exactly the same as those on halogen capsules, so if you’re replacing your current light bulbs with LED light bulbs and your fitting accepts one of the standard types listed here, you should be able to install them without an issue.

Linear Halogen

R7s Fitting

Cap Diameter: 7mm
Cap Length: 5mm
Bulb Length: 78mm/117mm

Linear Halogen light bulbs for floodlights and up-lighters have a 7mm R7s cap at each end of a long quartz linear light bulb. All linear halogen light bulbs have the same cap but come in either 78mm lengths or 117mm length light bulbs. They also come in a variety of wattages, so it is important that a replacement linear halogen is like-for-like (same wattage, same length).

Halogen and LED Spotlights

The most common halogen spots are either push fit (GU4/MR11 or GU5.3/MR16), low voltage type or twist and lock (GU10 or GZ10) mains 240V versions.

Spotlight bulbs can be identified by measuring the distance in mm between the centre of the two pins that extrude from the base of the spotlight.

The different distances between the pins and the size of the pins prevent the wrong type of spotlight being inserted into the wrong fitting.

GU10 Cap

Type: Twist and Lock
Distance Pin (Centre) to Pin (Centre): 10mm

Featuring two pins that twist and lock the spotlight into the fitting, the GU10 is the most popular spotlights used in the UK. This spotlight is mains operated 240V and was initially developed as a halogen spotlight but is nor widely available in LED. Various wattages, colours and beam angles can now be purchased to provide lighting in many different applications.

GU5.3/MR16 Cap

Type: Push Fit
Distance Pin (Centre) to Pin (Centre): 5.3mm

This base of this lamp is technically named GU5.3, however, the whole spotlight is more commonly referred to as an MR16. Featuring two round pins that push into the fitting, this is the 2nd most popular type of spotlight. The MR16 spotlight operates at 12V so requires a 12V transformer or driver to run- these drivers are sometimes built into the fitting but can also be purchased separately.

GZ10 Cap

The GZ10 spotlight looks very similar to the GU10 lamp, but there are two major differences. The GZ10 spotlight makes use of a dichroic reflector to direct all of the heat generated by the spotlight backwards, creating a cool beam spotlight. The GZ10 spotlight, therefore, features a square corner base (where the GU10 has a bevelled base). This stops the GZ10 being used in a light fitting designed for a GU10 where this backwards reflected heat could damage the fitting. Note: although a GZ10 cannot be used in a GU10 fitting, a GU10 can be used in either a GU10 or GZ10 fitting.

Fluorescent Tubes and LED Tubes

Fluorescent and LED tubes have a two-pin fitting at both ends of the tube.

G13 Fitting

Tube Diameter: 25mm (T8 = 8/8 inch)
Distance Pin (Centre) to Pin (Centre): 13mm

The most common size of fluorescent or LED tube is the T8 which uses a G13 two-pin cap on both ends of the tube. The distance between the pins is 13mm and when inserted into the fitting, the tube twists to lock into place.

Also found on T10 (tube diameter: 10/8 inch) and the larger T12 (tube diameter: 12/8 inch).

G5 Fitting

Tube Diameter: 16mm (T8 = 5/8 inch)
Distance Pin (Centre) to Pin (Centre): 5mm

There is a smaller tube size – the T5 which uses G5 two-pin caps. The distance between the pins is 5mm.

This cap can also found on less popular T4 (tube diameter: 4/8 inch).

Now that you can identify which cap you need for your light fitting, don’t forget to read our guide on choosing the right LED light bulb for you.

LED Lighting Sets the New Standard in Schools

Improving Health, Safety and Performance in Classrooms with a Simple Switch

Current State of Classroom Lighting

For over a century, fluorescent bulbs have been the groundbreaking technology in lighting. Since the 1940s, we have been educated under fluorescent lights in schools, worked under them in offices, exercised under them in gymnasiums, and treated under them in hospitals. With the advent of the compact fluorescent bulb, we even brought them into our homes.

Fluorescent lights are gas-filled tubes with a phosphorescent coating on the inner surface. Electrical current is passed through a voltageregulating ballast to a tungsten-coiled electrode. When the lights are turned on, a voltage “kick” from the ballast instantly (or, in older technologies, more gradually) vaporizes small amounts of mercury within the tube, causing them to emit ultraviolet (UV) light. The inner surface coating absorbs the UV light and converts it to visible light, producing a ‘white-ish’ glow.

With lighting a necessity in our lives, unfortunately fluorescent lights have become essential due to the lack of competitively priced technology with comparable light output and efficiency.

Current Impact of Fluorescent Lighting on Students

Mercury is a hazardous material. Fluorescent tubes contain a mixture of mercury and inert gases when current is running through them, and a broken fluorescent tube carries the risk of mercury entering the body through the lungs (via breathing in the gas) or the skin (from coming in contact with mercury residue on the inner glass surface). In the unforeseen event that a fluorescent light bulb shatters, anyone in the vicinity will be exposed to the dangers of mercury, making it a safety hazard in schools.

The mercury gas in fluorescent bulbs produces UV light, which is partially, but not completely, converted to light in the visible spectrum. Ultraviolet radiation operates at a higher frequency than visible light and is able to break bonds in many polymers, causing damage to materials such as plastics, as well as the tissues in our eyes and skin. Prolonged exposure can result in a clouding of the lens, commonly known as cataract formation, and is a contributing factor to age-related macular degeneration – the leading cause of blindness. Young people are especially at risk to the hazards of UV light, as a protective deposition of yellow pigments in the eyes occurs with age, attenuating the amount of radiation reaching the retina in older adults.

In addition to UV light, the visible radiation emitted by fluorescent light sources consists of three spikes (magenta, yellow-green, and orange), with minimal if any other wavelengths contributing to the output. The human visual system transmits those light signals to the brain, which must ‘fill in the gaps’ to process the picture. Students learning in poor-spectrum lighting environments often have a difficult time concentrating. Some people have extremely sensitive vision, particularly in the scotopic (low-lit) range, and low-spectrum lighting can trigger the same visual response. These individuals with scotopic sensitivity syndrome are commonly misdiagnosed with dyslexia or other learning disabilities, as well as being subjected to dizziness, headaches and nausea caused by the spikes and gaps in fluorescent light output.

The LED Lighting Technology Alternative

Light Emitting Diodes (LED) are a cutting-edge solid-state technology that are predicted by the US Department of Energy to replace almost all artificial lighting in the United States by 2030. While the basic technology has been available for years, recent developments have driven down cost and made LEDs more widely-available to the general public. Available as alternatives to everything from industrial and landscaping feature lighting, to residential settings, to the ubiquitous fluorescent tubes in schools and offices, LEDs provide a number of benefits over their predecessors. Known primarily for their energy efficiency, LED bulbs produce more lumens per watt, resulting in higher efficacy as less power is needed to produce the same or more light output. LEDs are also superior when it comes to quality of light output, as white tubular LED lamps provide the closest spectral match to sunlight (Graph 1), with no spikes or gaps in color output. And unlike their fluorescent counterparts, LEDs are 100% visually efficient; that is, they only produce radiation in the visible range, with virtually no harmful UV or wasted infrared.

Additionally, LED bulbs contain no mercury or hazardous waste, and are 100% recyclable. High-quality LED products can last up to 20x longer than any other artificial light source, reducing the time, cost, and effort of maintenance.8 These factors combine to make LEDs the clear choice over fluorescents.

Benefits of LED Lighting for Students

Good lighting aids cognition in many ways. This is especially important in the case of children and young adults.

Physical Utility

The smooth curve and constant irradiance across the full spectrum of visible wavelengths results in more saturated, vivid, discriminable color rendering and effortless visual acuity. Fully directional down-lighting also provides more illumination on working surfaces, rather than the diffuse glow produced by the gas-filled fluorescent tubes.

The correlated color temperature, color rendering, and luminous efficacy of LED lights combine to improve visibility to create a better learning environment. Vision is a contributing factor to an individual’s ability to attend and respond to classroom instruction.

Cognitive Utility Most parents encourage their children to get a good night’s sleep on a school night. A healthy sleep/wake cycle (or Circadian Rhythm) is crucial to mental cognition. Our bodies’ roughly 24-hour cycle is governed by hormonal responses that are triggered by full-spectrum light – light provided by sunlight and LED, but not fluorescent.9 When the light needed to trigger circadian responses is provided, alertness, attention and participation increase among students, as shown by a Case Western Reserve University study.10 Similarly, the US Army conducted a study with Tufts University showing that LED lighting resulted in increased productivity over fluorescent lighting.

LED

We have all experienced the relief of leaving a fluorescent-lit classroom and stepping outside for recess on a sunny day. The spectral output of fluorescent lights is to blame. In the bleak winter months, many people are diagnosed with Seasonal Affective Disorder (SAD), while many more self-diagnose their yearly “winter blues.” LED lighting is used in the treatment of SAD, and also has been shown to improve mood, decrease stress, and create a generally healthier and happier environment – all because the lighting spectrum mimics that of natural sunlight.

Conclusion

LED lighting is the best choice for schools that want to foster a safe, healthy, comfortable, and “green” environment for their students and teachers. The benefits range from monetary savings – from electricity costs and less frequent bulb replacements – to increased teacher productivity, student participation and learning, and ocular safety. These lights best eliminate the lighting-related competing element in schools that physically directly affects the students’ vision and physiologically affects their ability to and capacity to learn. Just like the societal revolution, LEDs are no longer the future of the lighting industry. They are the present, and should be the source illuminating future generations.
