I'm still having a hard time deciding with which COB I should go with...
Here are the options I've came up so far with the DIY Calculator :
1212 :
x 9 = 90euros + 100euros Heatsink = 190euros - PPFD = 813 @ 1.05A = 355w
1825 :
x 4 = 140euros for COB + 40euros Heatsink = 180euros - PPFD = 744 @ 1.4A = 304W
x 6 = 210euros for COB + 60euros Heatsink. = 270euros - PPFD = 848 @ 1.05A = 337W
1818 :
x6 = 115euros for COB + 60euros Heatsink = 175euros - PPFD = 796 @ 1.05A = 344W
Vero :
x 4 = 84 euros + 40euros Heatsink = 124euros =
x 6 = 126 euros + 60 Heatsink = 180euros - PPFD = 674 @ 1.4A = 333w
I guess my best options are either 1818 or 1212, but not sure which option would be the best regarding efficiency and weight I can pull from those setups.
Any opinions ?
