It gets costly building a Cob unit real numbers 120 cobs shipped to door 8000.00 you still need drivers, heat sinks , holders , lens , or reflectors etcBuild yourself ones rite? What does a completed kit cost to run.....say... 4x4 or 4x8 tables??
so all said n done your looking at 400 unit 41 bucks per cob x 8 heat sinks, drivers, misc , wire, and your time which i did not add i would safely say 500 - 550 for all parts not including metal or what your putting them into the box and that is 400 watts nd what people are 1.5 gpw on average @ 52 percent efficiency so no matter what 48 percent is still heat
with my set up 6000 watts i will in fact Dim them ... under drive them which will lower power and increase efficiency for instance this is what 1600 watts covering in 7 x 4 and change area 28 Sq feet ?? 57 watts per Sq foot
PPFD At about 4.65 umol/J, 1600 x .56 / 28 x 10.7 x 4.65 = 1592
