Quick question for you
@BigSm0 . I have one of those lux meters that people use to measure the lumens output of their MH/HPS. I know that PAR is the important metric for grow lights, but lumens is also a handy rough guide for knowing how far to put your lights and how much "light" they are pumping out.
My question is, can you use one of these meters in the same way for COB lights, or is the type/spectrum of light different and not measurable for one of these meters?
