Optics are an essential part of an LED lighting system. Without them, the best LEDs on the market will not grow your corals properly. The reason for this is that Optics (or lens) are designed to focus the light on your corals rather than your living room floor. To help you choose the right optics, please check out our optic right up for more information: Need help choosing the right optic?
**NOTE Optics will "slide on" but will not hold. DO NOT USE SUPER GLUE TO ATTACH THE OPTICS - The fumes from the glue can damage the lens. Use a tiny amount high temp silicon adhesive: Silicon lens / optic adhesive (high temperature) 45g

Ordered the 80 degree optics and they are wider than the LED stars. If you have the led's clustered close together the optics won't fit because they will touch. If optics weren't so wide, they'd be perfect...

This product works great with my aquarium lighting LEDs. This product efficiently redirects light so I know my corals are getting the light they need. At the great bargain, I was able to set up my entire full range system with these. My corals are looking happy and healthy, so I know this product is working!
