LED stage lighting has revolutionized live performances, offering energy efficiency, vibrant colors, and dynamic control options. With numerous products available, selecting the right LED stage lights requires careful consideration of several factors.
Key Selection Criteria
1. Brightness and Output
Lumen output: Determine required brightness based on venue size (small clubs 5,000-10,000 lumens, large venues 20,000+ lumens)
As we delve into the bright world of smart bulbs, it becomes clear that these are not just gadgets for tech enthusiasts but valuable tools for enhancing the comfort, security, and efficiency of our living spaces.
In the realm of home automation and smart technology, few innovations shine as brightly as smart bulbs. These advanced lighting solutions not only allow users to control illumination with unprecedented precision but also offer a spectrum of colors, integrate with home automation systems, and can even contribute to energy savings.
What Makes a Bulb “Smart”?
At its core, a smart bulb is an LED (light-emitting diode) bulb equipped with technology that allows it to connect to a home network, usually via Wi-Fi or Bluetooth. This connectivity transforms a simple light bulb into a device that can be controlled remotely through a smartphone app, voice commands via virtual assistants (like Amazon Alexa, Google Assistant, or Apple Siri), or integration with other smart home devices and systems.
Key Features and Benefits
Remote Control and Automation
One of the most immediate benefits of smart bulbs is the ability to control them remotely. Whether you’re in bed and realize you’ve left the kitchen lights on, or you’re on vacation and want to simulate someone being home, smart bulbs make it possible with just a few taps on your smartphone or a simple voice command.
Customization and Scenes
Smart bulbs can emit a wide range of colors and color temperatures, from warm yellows and cool blues to vibrant reds and greens. Users can create custom scenes or moods for activities such as reading, movie watching, or hosting parties. Some smart bulbs can even synchronize with music, games, or movies to enhance the entertainment experience.
Energy Efficiency and Cost Savings
LED smart bulbs are significantly more energy-efficient than traditional incandescent bulbs, and their smart features allow for more precise control over when and how lights are used, potentially leading to further energy and cost savings.
Security
The ability to control lighting remotely or set schedules can enhance home security by giving the appearance that someone is always home, deterring potential burglars.
Considerations When Choosing Smart Bulbs
Compatibility
Ensure that the smart bulbs you’re interested in are compatible with your home’s Wi-Fi network (2.4 GHz vs. 5 GHz) and any existing smart home systems or devices you have, such as smart speakers or home automation hubs.
Hub Requirements
Some smart bulbs require a central hub to connect to your home network, while others can connect directly to Wi-Fi. Consider which setup is best for your needs and whether you’re willing to manage an additional device.

If you’re already invested in a particular smart home ecosystem (e.g., Apple HomeKit, Google Home, Amazon Alexa), look for smart bulbs that integrate seamlessly with your system to ensure a smooth user experience.
Price
Smart bulbs are generally more expensive upfront than traditional bulbs. However, their energy efficiency and longevity can offset the initial cost over time. Consider your budget and the potential long-term savings when making your decision.
The Future Is Bright
As technology continues to advance, the potential for smart bulbs expands. Innovations such as Li-Fi (light fidelity), where light bulbs provide internet connectivity, or health-oriented features like circadian rhythm syncing, hint at a future where smart bulbs do much more than just light up a room. They could play a significant role in our daily lives, from enhancing our health and productivity to revolutionizing the way we connect to the internet.
In conclusion, smart bulbs represent a fusion of convenience, efficiency, and innovation. Whether you’re taking your first steps into home automation or looking to expand your smart home ecosystem, incorporating smart bulbs can brighten your home in ways you’ve never imagined.
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.

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.

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.

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.

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.
Fluorescent
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.
