Id just be careful with looking at led
fixtures such as this one mentioned. Its extremely easy to get suckered into paying for a junk piece of equipment. Even at 100-150 a piece, id hate to see someone spend theoney only to have the piece fail prematurely. If you find a fixture on ebay/amazon etc. try to find someone with that exact fixture. Ask them about it and get a feel for the product before committing, its way too easy for these overseas companies to ship you a product and disappear into the wind. This one here seems to be of decent quality. Only thing id question is 1) what brand are the leds and 2) what exact model of cree or bridgelux board arethey using.
