What Optics?

[Jaws]

Where would you say the cheapest place to buy optics are? I'd need almost 200 of them. Too bad I bought 150 of the 40 degree angles originally.

Send me the specs on you Leds as I will get a quote for you or send you directly to my supplier..

40 degree are ok but you need to mount those quite higher than the tank surface

I don't use any secondary optics on a 24" deep tank with the LEDs 8" off the water. Plenty of light for SPS all the way to the bottom. Tried 80 deg optics for the first 2 months, but didn't like the effect, too much top down light and not enough light from the sides. Corals look much better without the optics, and no "hot spots" or disco.
