I have been following along from the start and have been tinkering around with design layouts for an led light to cover a 72" x 30" x 24"h tank.
To everyone:
My big concern is how many 3W led per fixture(6 total, 30"l x 10.5"w).
I am not sure if my thinking is correct here, but with 25 degree led optics will I get a spread like my attached drawings?
The 2 drawings are not of the same fixture, I am just trying to figure out true light spread.
About 8" spread (each LED) from fixture(6" above tank) to about 18" depth(12" tank depth)...
Light about 6" above tank, LED light spread at bottom of tank about 13"...
I have pdf files of these which are much clearer but photobucket will not upload them.
Thanks

Your calculations are correct... I'm impressed someone remembers Trig. I would maybe space them closer together.
