I love my LEDs and would not go back. At my most insane, was running 3x250w DE & 6x150w DE, but these were each drawing a bit more so over 2000 watts of power and it was so hot in the summer from the lights that I had to run a 12000 btu AC and/or switch to reverse photoperiod.
This summer, probably the hottest and sunniest in Greater Vancouver since I've lived here (since the 70s), never once had heat issues or had to reverse my photoperiod or setup my AC.
My 165g main tank went from drawing roughly 600w in halide alone, to 280w max (12 x 10w Blues - 6@454nm & 6@445nm) (16 x 10w Whites - mix of 6500k; 10000k & 20000k)
My 2' cube went from 150w halide to 50w LED (3x10w blues and 2x10w whites) same mix as with the main tank lights.
The RSM 34g currently has an Eshine 60w Cree
