what do you mean by "line out" on one of the chips ? like is there a string of diodes within a certain cob that is not lighting up but most of the cob is?or are you talking about a wire going to one of the cobs ?
First part of what you said there is a line out close to the edge that is out but the rest of the cob is working
@CobKits do the citizens draw 36v @ 1400ma ? if these do like i think they do your over the limit on that driver and it goes into some type of safe mode limiting the output.your par numbers at 12 inches should be at least 600ppfd,i get 700 or more with softer driven cobs.my 35w cree (1050ma) are 600ppfd around 12 to 16 inches away.im sure those citi should be right there as well.maybe an older par meter is not reading the leds correctly.its not the same as reading a hps lamp,but the newer par meters are adjusted for leds as well as hid lights.
no bro,thank coberto,he's the one taught me all this crap about the shitizens lmao.also he prob has that driver for cheap,peace
if its mine and it has a string out pull it ill swap it. its hard to see that without a dedicated power supply, i cant look at a cob if its over 100 mA
both the gen6 and esp the 1216 are lower in voltage
