I became interested in the LED strip cobs as a replacement for the 8' T12 fluorescents in my tattoo shop, but the more I looked into them I wondered if they could be used for growing. I ordered eight of the 4' 5000k 80 CRI lights and a Meanwell driver to experiment with. If it works I have an alternative to my 16 COB Cree 3590 system. If it doesn't pan out the shop has new lights so I really can't go wrong.
8 x SI-B8R221B2HUS
1 x Meanwell HLG185H-C1050B
Using 22.5Vf the system will have a total forward voltage of 180V at 960mA. That should be a good match to the Meanwell driver and return an efficacy of 192 lm/W for a total of 33,248 lumens if my math is right. (Cap't Morgan may have been involved) That's similar to a four cob CXB3590 36V system running at 1.5A, but the cost is less at the same level of light. Once I get everything in and assembled I'll run my PAR meter under it and report back.
Anybody else using these Samsung lights?
