Can you describe your tank please WxLxD, what corals do you keep and how long and under how many LED at 10W per LED since you are not using Crees, your LED's can be close to EVO product although there is no way of knowing obviously.

My tank is a 77 gallon Hagen, 4' long, 16" sides & 24" deep. I have a DIY LED build thread going that provides plenty of details regarding the components I'm using.

To summarize for those not wishing to slog thru the whole thread, the fixture consists of 27 LEDs, all 10 watters. They are arranged on three aluminum rails with approx 5 inch spacing between each 10 watt array.
-Two outer rails each have five 10000K White & four 452-455NM Royal Blue,
-Center rail has five 460-470NM Blue & four 6000-7000K White

So potentially I have 270 watts of LED power over my tank. I've been running the fixture for a month now at 8 inches above the water surface & haven't even come close to running it at full power. Cost for components to this point is just under $600 & I'm reasonably confident the fixture will blow either of the EVOs out of the water. By comparison the 32 LED EVO will give you around 100 watts & the quad 200 watts at full power. How that translates into lumens per watt is anyone's guess, but I'm quite pleased with my DIY effort. For coral I have mostly softies but also a hammer & several sps, but not sps heavy. Everything's doing very well following the transition from my 2x250 watt MH, T5HO combo.
