Quick LED optics suggestion?

[JonnyIce]

Looking to put together an LED canopy for my 26" wide, approx 8" deep little frag tank...I am getting 12blue 12white 6red Cree LEDs and curious as to suggestion for optics? The fixture is a canopy so it will be like 5" or so from water line. I like the idea of optics, but with the three colors I don't know if so close to the water it will just look like the late 90s at Webster Hall lol. Any ideas? The optics I would be getting narrow down to about 32degrees and about 78% efficiency. Thanks!:iamwithst

32 is like a super tight flash light. At that hihht and depth no need for optics

+1 no optics required

Thanks I'll worry about it later aka when a commercial one with optics will be cheaper anyway haha
