so here's my preliminary thoughts about a lighting system in the 4 x 8 bloom tent:
each unit will be
6 - BXRC-35E10K0-D-73-SE COBs 3500k 80cri running on 1050ma constant current @27.00 each
6 - pin passive heatsinks @18.50 each
1 -
HLG-240H-C1050 @69.00
total lighting cost per unit ~342.00
so adding $58 for miscellaneous parts (wire, frame material, nuts and bolts, ...)
talking $400 per unit
from the bridgelux spec for those COBs:
1050 - typical constant current
35.4 - typical Vf at 25c
37.2 - typical power at 25c
6911 - typical flux in lm
6734 - typical DC flux lm
186 - efficiency lm/w
If I build 3 of these units to fill a 3 x 6 area, I'm thinking I can service the 6 plants per bloom cycle that I want for ~$1200
can anyone spot any flaws in this logic? am I missing anything?
I think 37w per cob power consumption won't really generate a ton of heat
I'm just spit ballin here, all comments are welcome
