Question? Has anybody used any of those leds, they are real cheap on ebay I was just wondering if they really worked? And can that big 90 watt led really replace the power and lumms of a 400watt hps fixture??? I have had good results on ebay so far, but I know you gotta be carful I dont know who said it buts it really good to check feed back esp on items sold that your intrested in.
