How Light Filters Work
Available as overlay panels for ceiling fixtures and slide-on sleeves for exposed tubes.
Overlay Panels
Less glare, softer light, and UV protection without changing the fixture. Overlay panels lay directly on top of your existing 2x2 or 2x4 ceiling diffuser. A patented micro-reflective polymer reduces the harsh edge of the light and blocks UV before it reaches the room. Works with LED troffers and parabolic, prismatic, or flat-lens fluorescent panels.
Tube Sleeves
Same glare reduction and UV protection, sized for exposed fluorescent tubes. Tube sleeves slide directly over T5, T8, and T12 bulbs when there is no diffuser to overlay. Common in shop lighting, garages, warehouses, and utility spaces.
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
NaturaLux light filters install on your existing fluorescent and LED ceiling fixtures without replacing the fixture or bulb. All three products reduce glare, block UV, and improve color rendering (CRI 88 to 95.3) while retaining about 80% of visible light. The difference is which fixture they fit.
Choose Fluorescent Light Covers if your fixture has a removable diffuser, louver, or lens panel. These are the most common ceiling fixtures in schools, government buildings, and older offices.
Choose LED Light Filters if your fixture is a flat 2x2 or 2x4 LED panel. These have largely replaced fluorescents in modern office and healthcare retrofits.
Choose Fluorescent Tube Covers if the bulbs are fully exposed with no diffuser. Common in shops, garages, warehouses, and utility spaces.

Made for Spaces Where Lighting
Affects Comfort and Focus
Most customers come to us because the light is uncomfortable to work under. What people usually notice first is reduced glare and less strain over the course of the day. NaturaLux filters are installed in over 30,000 spaces, and the most common outcomes are fewer overhead lighting headaches, less afternoon eye fatigue, less light sensitivity discomfort, and for people with lupus or UV-sensitive conditions, real protection at the fixture.
The room still feels bright, but the light is less sharp and tiring by the end of the day.
Also blocks up to 98% of UVA. Matters in labs, healthcare, and for people with lupus or UV-sensitive skin.
The 20% reduction targets excess glare, not the usable light. Most people say the room feels brighter, not darker.
Install once. Most filters outlast several rounds of bulb replacements.
How NaturaLux Differs from
Decorative Light Covers
Decorative covers soften glare by blocking a large percentage of room light. NaturaLux improves light quality while keeping the space usable and bright.
| Decorative Covers | NaturaLux Filters | |
|---|---|---|
| Purpose | Aesthetic: hide or decorate the fixture | Light quality improvement |
| 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 |

Popular in Offices, Classrooms, and Healthcare
Office Lighting
Harsh overhead lighting is one of the most common workplace complaints. NaturaLux filters reduce glare and soften the light without replacing the fixture or calling an electrician.

Softer, more balanced overhead light can make classrooms feel calmer and easier to work in. Teachers and students both notice the difference.
