Ahhhh, Tritonium. This is the coating on ALL of our OceanLED lights lens. Check out this video about just how easy cleaning your lights can be.

I was present for another cleaning that was even worse and was amazed at the process. Barnacles - gone in a flash.
The light in this video is one of our sand-blasted (180-degree) lights, so the LED's will look a bit fuzzy. (That's on purpose with this special-application light.) Easy to install, use, and clean - that's our lights.
