I choose to go the
LED route. This unit has the par compared to halides below and all whites, blues, red
uv, are on seperate controllable channels with a timer control matched to the unit. It will run independent of my RKL because of this. My RKL will run the wave pumps, heater, return, skimmer, pumps, and refugium light. The readings were done 15" above water level. Mine will be mounted 7-10 inches above.
Here is our Par readings compared to a metal halide. This was done on a 55g tank, with a 250w metal halide and our
LED lighting system.

This is alot of light that pics don't do justice to.
