I used an old marineland 48" T5 fixture to make an actinic fixture for my 75 gallon.
I got a supply of LED and a power supply from afriend that orders from china. I gota great price and the total was $80 for the PS and 20 royal blue LEDs. he gave me 4 whites to bring the total to 4 rows of 6. the glue is $10 for enough to do 30.
on. it's insanely bright
you will notice that I blew a couple of LEDs and one group of 6 is not lit. I should have diagrammed out or thought more before i hooked up the parallel part. i had hooked up one too many wires.
Still just 15 blues and 3 whites. 54w, the power of just one of the T5HO
All my lights on, 2 white 54w 2 actinic 54w and then a 2x96 watt PC one white one actinic.
now all the lights with the blue
the picture does not do justice to the amount of POP. Tomorrow I will mess with optics to see if they help. I also bought some computer CPU heat sinks. they were bargain bin $1.99, so i got 7. they have fans too, I might put those on a separate wall wart. this thing gets hott.
