Led Lighting choices. Strip or par 38 pendants?

[mike31154]

Aside from strip lighting & par38, there are also multi-chip LEDs that work very well for our application. They range from 10 watts each to well over 100 watts and are now available with multi colours on the same chip. Kessil uses a custom multi-chip in their light if not mistaken. I'm running a diy 10 watt multi-chip fixture over my 77 gal Hagen tank. It consists of 3 rows of 9 multi-chip LEDs per row with a mix of cool white, 10000K white, blue & royal blue. So theoretically I replaced 500 watts of MH + 130 watts of T5HO with 270 watts of LED. But I don't run the LEDs at 100%, so I'm not even consuming the full 270 watts. For me, switching to LEDs was one of the best moves I've made with respect to efficiency in keeping the tank running. Link to my build thread is below.
