Who Uses Make Great Light?​

These are great! They make such a difference in my office. Fluorescent lighting can sometimes trigger migraines for me and these have significantly cut down on light sensitivity issues at work. They were so easy to install too. Highly recommend!

Questions about Our Tube Filters

A: The fluorescent light tube covers come in 4 foot lengths and 3 widths: T5 T8 T12. The T8 size is the most common size and about the diameter of a US quarter.

A: One of the most common reasons customers purchase our NaturaLux fluorescent light filters is because their existing lighting is too bright. Overly bright lighting causes glare, and glare causes headaches, eyestrain, visual fatigue and blurred vision. NaturaLux filters only reduce light output by 20%, allowing 80% of the light through. By reducing the over-abundance (20%) of light, the glare is eliminated.

A: The tube filters would work if the LED is a standard 4′ in T5, T8 or T12 thickness. If it looks like an old, long fluorescent lamp then it’s probably standard size.

A: Our fluorescent light filters eliminate 100% of UV up to 380nm, up to 99% up to 390nm, and up to 80% up to 400nm. Many customers with UV sensitivity have told us that they can easily work under the filtered light for an entire shift with no effects from the UV rays.

A. Our tube filters are very versatile and can be used on fixtures that are flush to the ceiling or suspended. 


All NaturaLux fluorescent tube covers are made from a tough, heat-resistant polycarbonate.
