These apparently use bridgelux chips. any thoughts on this company? Also I have aluminum channel from a 2 pole telco rack. What if I attach salvaged PC heatsinks inside the channel right over where I mount chips. Will this be an effective heatsink? Planning on putting entire assembly inside 5" vinyl fence post and ductin air out with a 4" 100 cfm inline fan.

I'd stay away from anything on eBay.

Oh Gawd. It seems like once a month someone brings up these pieces of shit COB's. @FrankenGrow run away,... run very far away.
