I'm confused!

But 96 Cree leds on a 4' tank is way overkill, just get a controller and keep them dimmed to about 30% or so.

 

i didnt put it together yet waiting on replies so would 72 be overkill im trrying to cover the whole tank and i have 80 deg optics so how many crees will do. mix sps lps softy ext.

 

Mike recommended the ultra premium 48-56 LED's with 60 degree optics for me on a 90 tank with all SPS, fyi. My fixture will be about 10 inches above the water.

 

Have you read these threads?
