These light stabilized unbreakable clear poly-carbonate U. V. filtering sleeves are designed to provide protection in case of fluorescent lamp failure. In addition to containing broken glass particles and lamp chemicals, which protect personnel from injury, the Fluorescent Dimming Sleeve allows you to regulate the light output or reduce lamp glare by simply turning the sleeve with your fingertips to your desired comfort level. End caps are included. For use with F28-T5, F32-T8 & F40-T12 lamps. These sleeves are neither recommended nor guaranteed for use with high output T5 lamps.
The unit does exactly what I needed. Quality construction.
I was on thier site, Fixture too high for measurement. Snapped a pic, sent it to them asking what size and model should order so the bugs don't collect on the solid lens. Received a quick email with correct product. Installed over the weekend, perfect! Dont complain about shipping costs, increadible packaging!
Was happy with the lens cover, it was the exact one that I needed, worked out well, 1 time buyer
It fit perfectly. I loved the idea of the samples to see which one fits. Great idea
