Hello all on RIU!!
I figured I would start my build thread tonight since I made most of the orders today. It's going to be a 4 cob light using vero 29 gen 7's. 3000k 80cri FV of 52v. They will be driven @ 1050mah with a meanwell HLG-240H-1050B. Heat sinks are going to be 4 Arcitc Alpine 64+ CPU coolers. I will include some links to the places I bought/buying the components to try and make things a little easier. I'm also building a flower initiator , It will have one 350mah driver and 3 cree xpe far red led's :)

I would recommend the C or D version over the B version. Better performance according to data sheets. I built my light with Bs thouh

119 l/watt @ 2.1 amps, I'm driving it at half that, I'm assuming it's going to be around 145 ish l/watt @1050. I'd have to drive the 36 v one harder and the 69v one would not fit on my driver , The 320 is another 40-50 bucks.

as i understand, you may want to stay away from the far red led's.

Red (620-660nm): It's your main photosynthesis driver, duh. PSI and PSII photosynthesis pathways require two photons, one 680nm and one 700nm. Red LEDs typically come in a nanometer peak around 620-630, which means you don't have to waste much photon energy as heat in order to get usable photosynthesis energy.

Far Red (740nm) Don't waste your time. Like I mentioned twice before, photosynthesis needs one 680nm and one 700nm photon. Plants cannot convert a photon upwards in energy. To do so would violate the law of conservation of energy.
