Lithonia Lighting 2 ft. White LED High Bay Light 11200 lumwnS @HD $199

Hey GrayD I just took a look at them and offhand I wouldn't trust anything Lithonia makes personally, but the lumens it supposedly puts out is probably because of the 4000K's heavier green content. No UL Code Rating. Probably puts out quite a bit of heat I bet. For that money you could buy 4 4ft LED tubes on Ebay. Get 90 degree beam angles and you don't really need a reflector. Low CRI and medium power Nichias make me say you might be able to veg with them, but forget flowering with any kind of weight.
