You can tell me about the quality etc, blah, blah, blah. Its still way over priced. I have nothing against paying a fair price for a quality product, but this is utterly ridiculous! I'd be willing to pay double the price I payed for my chinese units to get a higher quality. I wouldn't pay 3 times that amount for half the power! Come on, I know they have a good product but paying $480 for a 75 watt ( ooooh its 180 equivalent... ) is nuts. My generic unit cost me $129 shipped for a 185 watt ( 300 equivalent ). I'd willingly pay $300 for this light, if it had a bit higher quality ( nothing wrong with it at all, its well made actually ). I understand about " binning" too, I've looked at buying 1st bin LEDs to build my own lights. They cost about 25-30% more. Paying more for quality parts makes sense as your likely to get a longer life from your investment. Paying TOO much for the same thing makes no sense to me and sooner or later, their pricing is going to bite them on the ass!
