Ok so I've been very interested in going led for some tome time now, I was stumbleing around through the endless websites looking for cheap and quality led's "cree,bridge lux,lenox,etc......" and then I looked on a website I found the link to in the group buy forum,right in front of my eyes lol I've been looking at that post for weeks lol. So I neadnerd around that site for awhile ,then I found the 50w 100w and 200w led's. The 50w comes in cool white and a 440-460nm blue . So I'm pretty much sold . And the kicker ITS 35 BUCKS!!!!!!!!!!!!
