Will these help with autism spectrum disorder or ADHD?

Yes. Our light filters are widely used in sensory environments and specialized learning facilities. Research shows that up to 50 percent of individuals with autism have severe sensitivity to fluorescent lighting, and approximately 69 percent of people with ADHD report being oversensitive to light. NaturaLux filters eliminate the flicker that triggers sensory sensitivities, reduce glare that causes visual overstimulation, and create more natural light that reduces stress.

What is the difference between the LED Light Cover and the Fluorescent Light Cover?

They provide the same benefits and are made exactly the same. They are listed separately to make it easier to find a product that fits a specific application.

What are the physical specifications of your filters?

Flat Panel Covers: 23.25 inches by 48 inches by .015 inches, 0.7 pounds per panel, made of modified impact acrylic, 91.7 percent light transmission, less than 1.8 percent haze, Class A fire rating ASTM E84, 100 percent UVB and 98 percent UVA blocking, 10 plus year lifespan, raises CRI to 95.3. Tube Covers: Available in T12 (0.28 lbs), T8 (0.2 lbs), and T5 (0.1 lbs), made of heat-resistant polycarbonate, 6 to 7 year lifespan, not suitable for T5 HO high output bulbs.

Can these filters work in very hot environments?

Yes. Our flat panel covers have a continuous service temperature range of 150 to 170 degrees Fahrenheit, deflection temperature under load of 176 degrees Fahrenheit, and Vicat softening point of 227 degrees Fahrenheit. They are designed to safely withstand the heat that fluorescent and LED light fixtures can emit.

Do you have fire safety certifications?

Yes. Our fluorescent and LED light covers have received a Class A fire rating from ASTM E84 testing performed by HPVA Laboratories. This is the highest fire safety rating for building materials and makes our products safe for schools, hospitals, and government facilities.

Will these work with my existing light bulbs?

Yes. Our fluorescent light covers are designed to work with your existing light bulbs and lamps. No special bulbs are necessary. However, for optimal results, we recommend using bulbs in the 4100K to 5000K color temperature range.

How do fluorescent light covers reduce glare?

NaturaLux filters use a special highly reflective coating on our material. The excess glare is bounced back into the light and not at people underneath the lighting. Excess glare is completely eliminated through this reflective polymer technology.

Are these decorative fluorescent light covers?

No. NaturaLux light filters are clean and professional looking optical devices designed for visual ergonomics. Our filters don't have fancy distracting designs. They are precision-engineered to actually change the light output through glare elimination, UV blocking, and color correction, not just provide decoration.

Can fluorescent light covers improve health?

Fluorescent light covers help mitigate many of the negative side effects of working under fluorescent light for a prolonged period of time. NaturaLux filters with filtering capability truly transform the light by eliminating glare that causes headaches and eyestrain, blocking UV radiation that can cause health issues, providing full-spectrum light that supports mood and sleep regulation, and reducing visual stress that leads to fatigue.

What type of fixtures can I use these covers on?

Flat panel covers are designed for most common recessed light fixtures. If your light fixture is flush with the ceiling such as a parabolic or prismatic fixture, they will work. Tube covers work in fixtures where there is no supporting panel or louver, including fixtures that are flush to the ceiling or suspended. The overlay light filters are oversized and can be trimmed to fit.

Do they work with LED lights?

Yes. The same properties apply to both fluorescent and LED lighting issues. Most of the time, the light cover can be trimmed to fit an LED light. Our LED light covers can be installed inside your existing cover if you are able to remove it, or affixed to the outside of the light fixture using double sided tape.

What UV protection do the ceiling light panels provide?

Our fluorescent light panels eliminate 100 percent of UV up to 380nm, up to 99 percent up to 390nm, and up to 80 percent up to 400nm. NaturaLux filters absorb 100 percent UVB radiation (280-320nm) and 98 percent of UVA energy (320-700nm).

Can I return the product if it doesn't work for me?

Please read our return policy. If the product is in its original condition, then generally a return will be accepted. For specific return questions or to initiate a return, please contact us directly.

Why were these filters originally developed?

Our company was originally founded in Alaska, a place known for limited sunlight, specifically to address the challenges of poor lighting and its effects on mood, health, and productivity. NaturaLux filters were designed by a certified ophthalmologist to provide full-spectrum light that mimics natural sunlight.

How much do you reduce light output?

NaturaLux filters reduce light output by 18 percent, allowing 82 percent of the light through. You can expect a reduction of the light by about 18 to 20 percent. The glare will be removed and the light will be color corrected which softens the overall effect significantly.

Can I use two filters for extra light reduction?

Yes. For very intense lighting situations or super bright LEDs, you may need or want two filters in place on each light fixture. Using two filters provides approximately 36 percent light reduction while maintaining glare elimination and color correction benefits.

What makes NaturaLux different from other light filter products?

NaturaLux was designed for visual ergonomics by a certified ophthalmologist, not just to diffuse light but to optimize it for human vision and health. We use specially engineered materials with embedded pigments and UV-absorbing compounds, maintain a Class A fire rating for safety, provide 10 plus year lifespan with no degradation, improve Color Rendering Index to 95.3, and block 100 percent UVB and 98 percent UVA radiation. Generic diffusers cannot provide these benefits.

Got Light Filter Questions? | Make Great Light

Q: Which type of filter should I choose - tube covers or flat panel covers?

Flat Panel Covers are designed for fixtures with existing plastic panels or metallic louvers. They sit on top of your current fixture and work for both fluorescent and LED fixtures. Tube Covers are designed for open fixtures where there's no supporting panel. The fluorescent bulb slides into the sleeve and is twisted back into place. Important: We do not recommend tube filters for T5 HO (high output) bulbs as they generate too much heat.

Q: How do I know what size fluorescent bulb I have?

Fluorescent bulb sizes are measured in 1/8 inch increments: T12 bulbs are 1.5 inches in diameter (12/8 inch), T8 bulbs are 1 inch in diameter (8/8 inch), and T5 bulbs are 5/8 inch in diameter. You can find this information printed on the bulb itself or on the box. Look for markings like F32T8SP35 where the T8 indicates the bulb diameter.

Q: Do these filters work with dimming systems or smart lights?

Yes. Our light filters work with existing lights and lighting systems, including dimmers and smart lights. There is no interference with any lighting controls or building automation systems.

Q: Are these safe for schools and healthcare facilities?

Yes. NaturaLux light filters have achieved a Class A fire rating from ASTM E84 testing, the highest fire safety rating for building materials. This makes them safe and compliant for use in schools, hospitals, government buildings, and other institutional settings where fire safety is critical.

Q: How do these compare to wearing tinted glasses for light sensitivity?

NaturaLux filters provide a permanent, room-wide solution while tinted glasses only help the individual wearing them. Filters treat the entire environment benefiting everyone in the space, create consistent lighting for all activities, and often eliminate the need for specialty glasses. Many customers who previously relied on tinted glasses find they no longer need them after installing NaturaLux.

Getting Started

What are NaturaLux light filters and how do they work?

NaturaLux light filters are professional-grade lighting solutions designed to transform harsh fluorescent and LED lighting into natural, comfortable light. Our filters eliminate glare, block harmful UV radiation, color-correct the light spectrum, and reduce visual stress. They work by using specially engineered materials with colored pigments and UV-absorbing compounds that filter the light as it passes through, creating a more balanced and natural lighting environment.

Which type of filter should I choose – tube covers or flat panel covers?

Flat Panel Covers (Overlay Panels) are designed for fixtures with existing plastic panels or metallic louvers. They sit on top of your current fixture and stay in place for years. These work for both fluorescent and LED fixtures. Once installed, they require no removal when changing bulbs – making them ideal for most office and classroom environments where the light fixture is flush to the ceiling.

Tube Covers (Tube Guard Sleeves) are designed for open fixtures where there’s no supporting panel. The fluorescent bulb slides into the sleeve, end caps are attached, and the bulb is twisted back into place. These are perfect for fixtures that are NOT flush to the ceiling or suspended without covers.

Important Note: We do not recommend tube filters for T5 HO (high output) bulbs as they generate too much heat. Please use flat panel covers instead.

Do Your Products Work with LED Lights?

Yes, our products work for modern LED lights as well. LED Light Covers

How do I know what size fluorescent bulb I have?

Fluorescent bulb sizes are measured in 1/8″ increments and designated by a “T” number:

T12 bulbs = 1.5 inches in diameter (12/8″)
T8 bulbs = 1 inch in diameter (8/8″)
T5 bulbs = 5/8 inch in diameter

You can find this information printed on the bulb itself or on the box the bulbs came in. Look for markings like “F32T8SP35” – the “T8” indicates the bulb diameter.

Installation & Setup

How difficult is installation? What tools do I need?

Installation is very easy and can be accomplished with basic tools. If you’ve changed a fluorescent bulb before, you can install our filters.

For Flat Panel Covers: You’ll need scissors or a utility knife, a ruler or straightedge, and clear packing tape. Installation takes 1-2 minutes per fixture. Simply measure your fixture, cut the filter to size, and tape it in place.

For Tube Covers: No tools needed. Just remove the bulb, slide the tube cover over it, attach the end caps, and twist the bulb back into the fixture.

See our detailed installation guide for step-by-step instructions.

Do these filters work with dimming systems or smart lights?

Yes! Our light filters work with existing lights and lighting systems, including dimmers and smart lights. There is no interference with any lighting controls or building automation systems.

Can I use these filters in damp environments like kitchens or bathrooms?

Our products are designed primarily for interior use in professional settings such as offices, classrooms, healthcare facilities, and retail spaces. While some homeowners have successfully used our light filters in their kitchens or living areas, our focus is on business-to-business (B2B) and business-to-government (B2G) applications.

What if my fixture has an unusual size or custom dimensions?

Our flat light covers are made of flexible, thin material that can be easily trimmed to size with scissors or a utility knife. The standard size is 23.25″ x 48″ x .015″, which can be cut to fit virtually any fixture smaller than this. For non-standard installations or questions about sizing, please contact us for guidance.

Do the filters need any special cleaning or maintenance?

No maintenance is required. Our flat light covers feature a matte finish on one side that naturally repels dust and dirt. Our tube filters are easily removable when you need to change light bulbs – simply remove the bulb with the filter still on it, then reinstall. The filters themselves never need to be cleaned or replaced under normal use.

Health & Medical Benefits

Are these safe for schools and healthcare facilities?

Yes. NaturaLux light filters have achieved a Class A fire rating from ASTM E84 testing, the highest fire safety rating for building materials. This makes them safe and compliant for use in schools, hospitals, government buildings, and other institutional settings where fire safety is critical.

View our Fire and Safety Data

Will these help with autism spectrum disorder (ASD) or ADHD?

Yes. Our light filters are widely used in sensory environments and specialized learning facilities. Research shows that up to 50% of individuals with autism have severe sensitivity to fluorescent lighting, and approximately 69% of people with ADHD report being oversensitive to light.

Harsh fluorescent lighting can increase repetitive behaviors, cause sensory overload, reduce focus, and contribute to meltdowns in individuals with autism or ADHD. NaturaLux filters address these issues by:

Eliminating the flicker that triggers sensory sensitivities
Reducing glare that causes visual overstimulation
Creating more natural light that’s easier to process
Providing consistent, comfortable lighting that reduces stress

Many schools and therapy centers report significant improvements in student engagement, attention, and behavioral regulation after installing NaturaLux filters.

How do these compare to wearing tinted glasses for light sensitivity?

NaturaLux filters provide a permanent, room-wide solution while tinted glasses only help the individual wearing them. Here are the key differences:

NaturaLux Filters:

Treat the entire environment, benefiting everyone in the space
Professional-grade solution that addresses the root cause
Never need to be worn or remembered
Create consistent lighting for all activities
Often eliminate the need for specialty glasses

Tinted Glasses:

Only help the person wearing them
Must be worn constantly and can be forgotten
May not be practical for all situations
Don’t address the underlying lighting problem

Many customers who previously relied on tinted glasses find they no longer need them after installing NaturaLux. However, the two solutions can work together if needed for severe sensitivities.

I get migraines and headaches from fluorescent lights. How quickly will I notice a difference?

Immediately. The results can be felt as soon as the whole area is covered with NaturaLux lighting. Most people report relief from eyestrain, headaches, and visual fatigue within the first day of installation.

For best results, ensure all lights within an 8-foot radius are filtered. Mixing filtered and unfiltered light will dilute the effects and may not provide complete relief.

Do these actually help with Seasonal Affective Disorder (SAD)?

Yes. Our products help balance the color spectrum to be closer to natural sunlight, which is beneficial for people with Seasonal Affective Disorder. Our company was originally founded in Alaska – a place known for limited sunlight – specifically to address these challenges.

NaturaLux filters don’t just reduce harshness; they actively improve light quality by:

Raising the Color Rendering Index (CRI) to 95.3 (compared to 88.4 for standard bulbs)
Balancing the color temperature closer to natural daylight
Providing full-spectrum light that supports mood regulation
Enabling serotonin and melatonin production

While they’re not a replacement for medical treatment, many users report improved mood and energy levels, especially during darker months.

Will these protect me from UV exposure if I have lupus or photosensitivity?

Yes. NaturaLux filters provide exceptional UV protection:

100% UVB radiation blocked (280-320nm)
98% UVA energy blocked (320-400nm)
Specifically: 100% UV up to 380nm, 99% up to 390nm, and 80% up to 400nm

Many individuals with lupus have reported they can now work under filtered lighting for an entire shift with no adverse effects from UV exposure. This makes NaturaLux an essential accommodation for employees with photosensitive conditions.

Product Performance & Comparison

How do these compare to just changing the bulb color temperature?

NaturaLux filters do much more than change color temperature:

NaturaLux Filters Provide:

Glare elimination – This is the primary cause of headaches and eyestrain, and cannot be achieved by changing bulbs alone
Color temperature enhancement – Raises the effective color temperature without needing expensive specialty bulbs
UV blocking – Standard bulbs still emit harmful UV radiation
Color correction – Improves Color Rendering Index (CRI) from 88.4 to 95.3
Long-term stability – Bulbs’ phosphors degrade over time; our filters maintain performance for 10+ years

Even if you use 5000K bulbs, you still need our filters to eliminate glare and block UV radiation – two benefits that bulbs alone cannot provide.

What’s the difference between your product and generic light diffusers from hardware stores?

NaturaLux was designed for visual ergonomics by a certified Ophthalmologist – not just to diffuse light, but to optimize it for human vision and health.

Generic Diffusers:

Simply scatter light to reduce brightness
No color correction
No UV blocking
May increase glare in some cases
Not engineered for health benefits

NaturaLux Professional Filters:

Spectrally engineered to enhance specific wavelengths
Eliminate glare through reflective coating technology
Block 100% UVB and 98% UVA radiation
Improve Color Rendering Index to 95.3
Clinically tested for visual ergonomics
Class A fire rating for institutional safety
10+ year lifespan with no degradation

Do the filters yellow or become cloudy over time?

No. The filters will never yellow or fade over time. Unlike generic plastics that degrade from UV exposure, NaturaLux filters use UV-absorbing materials specifically designed to prevent discoloration and maintain optical clarity for over 10 years.

Our overlay panels maintain performance for 10+ years, and our tube covers perform for 6-7 years of continuous use.

What’s your warranty policy? What if a filter doesn’t fit or gets damaged?

Please contact us directly for replacements or installation questions. We stand behind our products and will work with you to ensure you have a successful installation.

For returns, please read our return policy. If the product is in its original condition, returns are generally accepted.

Will these reduce my energy costs?

Yes. NaturaLux filters can help reduce energy costs through improved light quality. When lighting is color-balanced and color-corrected, the quality of light is noticeably improved – meaning you need less of it.

How it works:

Many facilities operate with 3-bulb or 4-bulb fixtures at full brightness
After installing NaturaLux, you can often reduce to 2 bulbs per fixture
The improved light quality means less quantity is needed
Quality lighting > quantity of lighting

Additional Cost Savings: Many businesses also see indirect savings through:

Reduced absenteeism from migraines and light-related illness
Increased productivity (less eyestrain = better focus)
Lower worker’s compensation claims
Improved employee retention and satisfaction

Download our Savings Calculator

Will my space be much darker with the filters installed?

NaturaLux filters only reduce light output by 18%, allowing 82% of the light through. For most spaces, this is ideal because:

The Problem: Most commercial spaces are over-lit, creating excessive glare. This glare causes headaches, eyestrain, visual fatigue, and blurred vision.

The Solution: By reducing the over-abundance of light by approximately 20%, the glare is completely eliminated while maintaining more than adequate illumination.

For extremely bright environments, you may choose to use two filters per fixture for additional light reduction, or you can remove one bulb per fixture for optimal lighting levels.

How do I know if I have glare in my office or workspace?

Here’s a simple test: Place your open hand above your eyebrows as if you’re saluting. If it becomes much easier on your eyes when you do this, you most likely are dealing with glare.

Other signs of glare include:

Squinting under overhead lights
Headaches that start or worsen at work
Eyes feeling tired by mid-afternoon
Difficulty focusing on computer screens
Feeling relief when you step outside or go home

Technical Specifications & Compatibility

What color temperature bulbs should I use with NaturaLux filters?

For optimal color balance, we recommend using either 4100K or 5000K bulbs.

Our testing shows that:

3500K bulbs are too orange and don’t provide adequate color rendering
6500K bulbs are too bluish-green and create visual discomfort
4100K to 5000K provides the best balance when combined with NaturaLux filters

The filters will work with any bulb, but you’ll achieve the best results with bulbs in this recommended range.

What’s the difference between using NaturaLux filters and “full spectrum” bulbs?

Full Spectrum Bulbs:

Use a mixture of red, green, and blue phosphors for better initial color rendering
Red phosphors decay at an accelerated rate
Lose their “full spectrum” properties over time
Still emit UV radiation
Still create glare
Performance degrades significantly before end of bulb life

NaturaLux Filters:

Use engineered colored pigments embedded in plastic material
Achieve natural, color-accurate, and color-balanced light
UV-absorbing material prevents fading or discoloration
Maintain consistent performance for 10+ years
Eliminate glare regardless of bulb type
Work with standard, less expensive bulbs

The key advantage is long-term consistency. Our filters maintain their optical properties for a decade, while full spectrum bulbs begin degrading within months.

Purchasing & Ordering

Can I test the filters before committing to a large order?

We do not offer free samples, but we have specific recommendations for testing:

For Individual Testing: Cover all lights in an 8-foot radius around the person who will benefit most. This ensures you get the full effect without diluted results from mixed lighting.

For Facility Evaluation: We recommend starting with a small enclosed room or office where you can filter all the lights. Testing in an open area where unfiltered light mixes with filtered light will dilute the effects and prevent you from experiencing the full benefit of the product.

This approach allows you to properly evaluate the product before scaling to a larger installation.

Product Selection & Use Cases

I’m looking to tone down the brightness of our LED lights. Will this work?

Yes. Our LED light covers will effectively tone down brightness. NaturaLux reduces light output by approximately 18% while eliminating glare and color-correcting the spectrum.

For Super Bright LEDs: Some LED fixtures are extremely bright. Many customers have successfully used two filters on each light fixture for additional light reduction. This provides:

Approximately 36% light reduction (when doubled)
Complete glare elimination
Softer, more comfortable lighting
Improved color spectrum

The glare will be removed and the light will be color-corrected, which softens the overall effect significantly.

What color are the filters? Will they look strange in my space?

The light covers have a purple-ish blue hue that is specifically engineered to enhance the color spectrum. They do not come in any other colors – and that’s a good thing, because any other color would not be effective at providing the visual ergonomic benefits.

Important to know:

Once installed, you likely won’t notice the color of the filter very much
They blend in and provide a professional appearance
The purple-blue tint is necessary for proper color correction
The light that comes through appears natural and balanced, not purple

Think of them like polarized sunglasses – the lens has a color, but what you see through them is clear and enhanced.

Do the filters come in different colors for decorative purposes?

No. NaturaLux filters are precision-engineered optical devices, not decorative products. The specific purple-blue color is scientifically formulated to:

Correct color temperature
Enhance the full light spectrum
Block specific harmful wavelengths
Improve Color Rendering Index

Changing the color would compromise these essential functions and eliminate the health and performance benefits.
