Bump. I just saw an advertisement about this at a local hydro store. 1500 watts and 206,000 lumens = 137.3 lumens/watt!!! Holy shit! Thought the efficiency would be tumbling that high, but that's incredible. I mean, what, 600 watt super HPS is 150 lumens/watt? Damn.
Any growers out there get their hands on one of these puppies yet?
