I'm helping a friend with a DIY LED fixture for his reef project.
Since English is not our first language please bare with me with any spelling or grammar mistakes.
a bit of background of his project :
Soft corals and LPS tank
Tank dimensions : 60" x 24" x 24"
light fixture would be 6"-9" above the tank unless advised otherwise
he's getting all the hardware from Rapidled.com
will be getting 3 x Drilled/tapped 6" x 20" Black Anodized Aluminum Heat Sink
Basically he wants to know the best ratio between whites, blues and reds ( CREE unless advised otherwise )
if I'm not mistaken there are 108 LED spots.
I just want to mention that I'm using CREE XM-L U2 LEDs to light my Tropical Dart frog Vivariums and I'm very very pleased with them.
I know that lighting a reef has different variants to consider when putting together a light fixture. that's why I'm posting here to learn from all the experienced reef hobbyists.
We would appreciate your opinion of what LEDs would be he best bang for the buck and the rest of the hardware to fit the LEDs chosen as far as drivers, dimmer/controllers etc...
I'm using 120mm computer fans as active cooling over my fixtures and I guess that's what we will do for this project, well unless you guys advise otherwise .
Thanks in advance
