Lol… I had bought a few of those DOBs from a new supplier with a different design for $2 to play with. They are pretty neat but only 80 lumens per watt. I bought it because it claims to Target the 450-455 nm lspectrum range which I thought was pretty neat. That seems pretty targeted. It pulls a true 50 w from the wall which was a surprise from past dabblings with the ultra cheapo “grow” cobs from China. The supplier claims the diodes are bridgelux. Apparently, they started as a phosphors company and have some proprietary phosphor formulas…( May be crap). They do have some other products but have been trying to perfect “driverless” as their major product offering. They run hot as Hades tho. The chips we’re not sloppily made in any way. Thick aluminum mount plate. Clean seals around the cob. I won’t buy more but when I build out my cab I may put some of em I got in for wintertime side lighting. Won’t have to worry about the girls getting cold at all.
Anybody else played with any of em?
