If I understand the math correct 60 degree lenses would give me a 34" diameter 20" from the bottom and almost a 14" diameter 8" down. So If the light is 2" above the water there is still great coverage for my size of tank. From what I have read it sounds like 60 degree optics should match 150w mh.
So given the size of my tank, without optics the colours I add for full spectrum should be ok if I put one of each in the centre of the light. I'm thinking one of each without optics: red, green, violet, and neutral white. Then cool white and blue/royal blue with 60 degree optics running down the length of the light. Does that sound good? Do you think the 1.8" x 12" heatsink from modular led would be wide enough?
