I have two AI Sol Blues over a 60" 100G mixed reef set 12" above the waterline and turned parallel to the tank width and couldn't be happier. I get great coverage compared to their 6" legs and more light than my old 2x250w MH and 2x140w VHO's provided. Best of all I went from 880 measured watts to a maximum of 148 watts plus have the ability to ramp up and down at any color. Not only was I able to ditch the old lights, I also sold a 1/4 HP chiller than no longer ran, my house AC does not work as hard, my canopy fans and sump fan never run anymore and my evaporation was cut in hald so RO/DI life went up too. I am probably saving $50 to $75 a month on that alone, not to mention more efficient pumps and powerheads and combining or manifolding pumping functions like reactors and such on one pump. I also switched my 16G nano from a 96w powerquad PC to 2x Excotic Panorama LEDs so cut power there too.
