So are you saying 4 of the ES165's will be the same penetrating power as a 1000?
[and just for compairison sake, will the blackstar 500w or pro grow 400, 4ea wont??]

Heat is negligible but there is quite a bit of fan noise.
I'm using a Blackstar 500w right now and it's going OK but I'm starting to think I would have been better served getting two 240w units and putting them side-by-side in my 2'x4' tent. I've got 3 Northern Lights growing and the one directly under the light is doing great but the ones to the sides are noticeably thinner. However, I see no signs of the lower leaves lacking in light so I'm thinking the penetration is good. I don't know how it really compares to using MH/HPS, though, as this is my first LED run. I had to raise the light to about 2 1/2" above the tops as any closer and the light starts to bleach the plants. Heat is negligible but there is quite a bit of fan noise. It is nice to not have to run cooling ducts, though. The real test of this unit will be when I switch to 12/12 in a week or two. I've been tempted to throw in a couple flouros to help even out the lighting but I think I'll just keep it straight LED for this grow to see how it works on it's own.
Just a quick-and-dirty review for you to mull over.
sounds like you have the light too close to the middle plant and there is no room for the light to spread. try raising it up to 6" or 12" or whatever the recommended distance is - then it should irradiate the whole canopy better.

WOW, just read entire thread in 2hrs.....great great info here. And thanks for all the leg work GP73LPC!
I saw these when looking around for EVO's after reading Mr. X's post. I've not done LED myself, but haven't seen these mentioned yet so wanted to toss it out there for the experts.
