COBs are LEDs just a bunch in a small chip. I am running 14 - Citizen 1212 3500K 90 cri COBS as my main lighting in a 4x6x8 space. I run them at about 40 - 45 watts. They have a good "white" spectrum. I run 2 - royal blue cobs in veg and I added the AgroMax this grow because COBs have no UV and the 10000K blue is good also in mid to late bloom so my average watts is about 680 with the AgroMax. Here is some calculations on the Citizen Cobs:
Um. Late 40s or early 50s on the ones in back.
Front two(theres a tiny one in that pot too) are only around a month old, maybe a little over. I'll have to hop into the journal and count the days on those ones.
