I am tempted to build my own. Alot to learn about lights!

The marineland doubles have 6000k white
LEDS and blue LEDs. The reef version has 10000K white LEDS and Blue LEDS. So I think the double would be best if I buy ready made.
The rams have such beautiful irridesent blues! They look good under 50/50 tubes.
thanks much for the info.
