"I've spent years in a classroom watching students lose focus as the day went on. Harsh overhead lighting is one of the biggest problems nobody talks about."
Audrey Hinds
High School English Teacher & Co-owner, Make Great Light
Why Classroom Lights Work Against Learning
Most classroom fluorescent and LED fixtures were selected for energy efficiency, not visual comfort. They create three distinct problems: glare that bounces off whiteboards and worksheets, UV radiation that triggers headaches and eye strain, and a color spectrum skewed toward yellow-green (fluorescent) or harsh blue-white (LED) that overstimulates the nervous system. Students with sensory processing needs feel the color imbalance most acutely. Students prone to migraines react to the UV. Everyone in the room squints under the glare. Teachers spend 6-8 hours a day under these same fixtures and carry the headaches home with them.
Student Focus
Harsh overhead light overloads developing visual systems. Balanced, full-spectrum light creates a calmer environment where students can concentrate on learning instead of coping with discomfort.
Sensory Overload
Harsh glare and unbalanced color spectrum are common sensory triggers for students with autism, ADHD, and processing differences. Calmer light may help reduce meltdowns and increase time spent learning.
Teacher Fatigue
Teachers spend 6-8 hours under the same harsh fixtures every day. Eye strain, headaches, and afternoon fatigue are not personal failures. They are predictable responses to bad light.
UV Protection
Fluorescent tubes and LEDs emit UV radiation that affects skin and eyes. NaturaLux blocks 100% of UVB and up to 98% of UVA radiation while rebalancing the color spectrum to something closer to natural daylight.
Lighting quality affects every student and teacher in the room. For children with sensory processing differences or migraines, harsh classroom lighting can make school genuinely difficult to attend.
Same Fixtures. Full-Spectrum Light.
NaturaLux filters use a micro-reflective polymer coating that physically rebalances the light your fixtures already produce. The coating redirects excess glare back into the fixture, shifts the color spectrum toward natural daylight, and blocks 100% of UVB and up to 98% of UVA radiation. This is not dimming: 80% of your original light output stays in the room, just corrected from harsh to balanced. Why not replace the bulbs? Because new bulbs still sit in the same fixtures, still produce glare, and still require an electrician and a purchase order for every room.
NaturaLux panels are lightweight, flexible, and trim to fit with scissors. Teachers can install them without tools or maintenance staff, and the whole process happens without pulling students out of the room. For districts, that means no electrician bids, no procurement delays, and no disruption to the school day. One purchase order can cover every classroom in a building.
Works with LED troffers, fluorescent fixtures, and exposed tube lights.

Learn more →The science behind classroom lighting and student behavior is well-established. Research consistently shows that full-spectrum, balanced lighting reduces off-task behavior, supports academic progress for students with IEPs, and creates a calmer learning environment for everyone in the room.
Make Great Light co-authored a research whitepaper on the impact of natural light in specialized and general education classrooms. The data draws from peer-reviewed studies including Ball State University's 2018 research on full-spectrum lighting and Barrett et al.'s 2015 findings on the relationship between classroom design and learning outcomes.

Classroom Light Covers and Filters for Every Fixture Type
NaturaLux filters work with both LED troffers and fluorescent fixtures. No replacement, no electrician, no disruption. Choose the type that matches your ceiling.
Not sure which type? Most newer schools use LED troffers. Older buildings typically have fluorescent fixtures. Gyms and workshops often have exposed tubes.

Sensory-Friendly Classroom Lighting for IEP and 504 Plans
For students with autism, ADHD, or sensory processing differences, harsh overhead lighting isn't background noise. It is a continuous, unavoidable trigger. Glare and cold color temperature can drive agitation and make it genuinely harder to stay in a seat and learn. Teachers in these rooms feel the same effects, hour after hour.
NaturaLux filters address the root cause: they reduce glare by 90%, block 100% of UVB radiation, and may help reduce the harsh color imbalance that triggers sensory responses. The same filters help students and teachers with photophobia, migraines, and sensory processing challenges. Read the research behind classroom lighting accommodations.
IEP & 504 Accommodation
NaturaLux filters support sensory-friendly lighting accommodations because they:
- Modify the existing fixture, not a personal device
- Benefit every student and teacher in the room, not just one
- Cost under $40 per fixture
- Meet Class A fire safety requirements for schools
