That shouldn't be revealed on a public forum but I'm from here and there, lived in Lexington for a while but now elsewhere. If you couldn't tell from my forum sig I'm a big fan of Pro-Grow LEDS. I've used their lights now for going on 3 years and have never had an issue. I suspect I'll be able to grow with these long after the 3 year warranty period. I haven't noticed any diminished quality thus far. If you're going to buy some contact Ben first and haggle a discount, he'll give you one if you buy more than one light. I currently have two ufo (90w), three PG 180s, and one PG 550 (I don't think they sell those anymore). It's a total of about 1000w of total output and consistently gives 2 oz autos in 60-80 days from seed, that is unless I wind up w/ shit genetics or travel too often with my better half in charge of watering and feeding the babies
Don't buy BS Chinese LED lights off E-bay! They are crap I've had several, none lasted more than a year and you have almost no recourse to claim a warranty against them.
