Hello. What do you think about these COBs? Efficiency seems good and they cost 1/3 of vero29 and less than 1/4 of cxb3590.
I don't know the spectral data of the light and do not know how they work in grow practice, They are produced by Philips ... why are they so cheap? Never would you mount them on a your (affordable) light instead of famous brands(cree, bridgelux, citizen)?
for example 3500K 80CRI has 145lm/w adrive at 1200mA...not so bad for only 10US cob, isn't it?
