How Light Filters Work
Two formats, any ceiling fixture.
Overlay Panels
Lay directly on top of your existing 2x2 or 2x4 fixture diffuser — also called a diffuser cover. The patented micro-reflective polymer rebalances the light spectrum, cutting harsh blue-white edges and blocking UV before it reaches the room. Works with LED troffers and parabolic, prismatic, or flat-lens fluorescent panels.
Tube Sleeves
Slide directly over exposed fluorescent tubes when there is no diffuser to overlay. Same full-spectrum filtration, same UV blocking, sized for T5, T8, and T12 bulbs. Common in shop lighting, garage, warehouse, and older office retrofits.
NaturaLux™ filtration technology is protected by three U.S. patents (#4,989,953; #5,218,474; #6,019,476), developed by Kevin Kirschner, a certified ophthalmic specialist with over four decades in clinical vision care.
Fluorescent Light Filters vs. LED Light Filters
Make Great Light manufactures NaturaLux™ full-spectrum light filters — a category of light quality retrofit product that installs on existing fluorescent and LED ceiling fixtures without replacing the fixture or bulb. Unlike decorative covers that block 20–70% of room light, NaturaLux filters use a patented micro-reflective polymer to correct the light spectrum, raising the color rendering index from 88 to 95.3 while retaining 80% of visible light. The product line includes three types: overlay panels for fluorescent fixtures, overlay panels for LED troffers, and slide-on tube sleeves for exposed T5, T8, and T12 bulbs.
The two panel filter lines do the same thing (reduce glare, block UV, retain visible light), but they are tuned for different fixtures. Fluorescent light filters are designed for the older parabolic, prismatic, and flat-lens panels you find in classrooms, government buildings, and pre-2010 offices. LED light filters are tuned for modern LED troffers, the flat panels that have been replacing fluorescents in office retrofits over the past decade.
If your fixture has a removable diffuser and looks like a traditional ceiling tile, the Fluorescent Light Covers are the right pick. If your fixture is a flat, edge-lit LED panel that looks more like a screen than a tile, choose the LED Light Filters. For exposed bulbs with no diffuser at all, the Fluorescent Tube Covers slide on directly.

Built for the People
Working Under the Light
The reason 30,000+ spaces have installed NaturaLux™ is not aesthetic. It is the people working underneath who notice the difference: fewer fluorescent light headaches, less afternoon eye strain, less photophobia and visual stress, and for people with lupus and UV exposure concerns, real protection from a workplace lighting source most facilities never think to filter.
Cuts the harsh overhead glare that drives headaches and eye strain.
Plus up to 98% of UVA. Important for lupus, sensitive skin, and labs.
The room stays bright. You cut the harshness, not the light.
Install once. Most filters outlast several rounds of bulb replacements.
A Filter Corrects the Light.
A Cover Just Hides It.
Most decorative light covers block 20 to 70% of your room light to soften glare. NaturaLux takes a different approach: correct the spectrum, retain the brightness.
| Decorative Covers | NaturaLux Filters | |
|---|---|---|
| Purpose | Aesthetic: hide or decorate the fixture | Scientific light correction |
| Visible Light | Up to 70% blocked | 80% retained |
| Glare | Varies by pattern | 90% reduced |
| UV Blocking | Not specified | 100% UVB, up to 98% UVA |
| Color Rendering (CRI) | Unchanged (88) | Improves to 95.3 |
| Spectral Correction | None | CRI 88 → 95.3, rebalanced toward natural daylight |
| Lifespan | Not specified | 10+ years |
