it would be more correct to say "seems like the HID and the blurple mass procuded Led and the Cree Cob guys are passionate about thier lights",,,, because there are far more debates about the merits of Cree Cobs and blurple china lights ,
Hid is proven and many DIY led guys would rather steer someone towards bulbs before low watt led chips panels, its still sad to me that they are being sold to people, do they work, sure, but if your going to spend 3 plus months investing in a plant, why not get the most for your time, the Cree cob guys are all pulling 1.30 to 2.0 grams per watt
