Of course it's Supras fault again for talking all this high efficiency.
So I'm taking the plunge and doing a passive cooled high efficiency light.
It will be used over my usual double screen scrog in a 3x3 tent.
Parts are:
9-CXB3590 CD 36v 3500k's
9-800ma drivers
3-32" x 3.5" heatsinks
That's one COB per sq/ft and these are the numbers that Supra gave me that convinced me to do this build.
9 CXBs at .8A (26.5W) 62.3% efficient in a 3X3 = 14.9 PAR W/ft² or 740 PPFD averaged, 90W heat
