Hi, could you please help me to understand which is the best MW driver for 200-250W DIY cob led?
I will use an arctic64 active heatsink(alpine 11 seems to be small) so 25°C may be not utopy.
VERO29D need
37.2V at 1.4A
36.5V at 1050mA
and 38.7V at 2.1A
I' ve a 70x70CM grow box (2.3 ft) so i think 200-250W should be enought, isn't it?
Ley's see the driver oprions:
X5 COBs driving from HLG-185H-C1050 but it would give me only 191W but a very good efficiency, low heat, maybe a poor photons penetration but i'm not sure about that.
X4 COBs HLG-185H-C1400 would not give me enought volt MAX190V, 35.75V instead of 37.2V wiring in serie ..is it not a problem?
X4 COBs HLG-240H-C1750, same problem of the previous and may be the cheaper way to have some extra power in the future...someone say tgat VEROS are good to works harder than cree..
maybe I could I put 5 - 6 COBs on a HLG-120H-C1400? Why not?
i ve a lot of confusion about driver VOLTS...from meanwell datasheet what does it mean for example 95V ~ 190V (1050mA driver) or 71V ~ 143V(1400mA driver)? how could i choose the Voltage output, i know that with internal(A version) or external(Bversion) mean well drivers i can only choose AMPERE output and not Voltage...Am I wrong?
I really hope for a your suggestion also for alternative COB alternative like CITIZEN OR CREE CXB3590 if you think are better(vero29D seems the best choice right now!)
many thanx!
regards
