Hello All,
I have been messing around with an old chinese cob light--9 orange looking full spectrum cobs-- After taking it apart it had a driver for each cob.
40-60v 1.2a. I took out all but four of the cob drivers and replaced cobs with some citizen 1212 3500 I found real cheap on ebay. I now have a four cob spread of 12" square. I thought this would be good for vegging a 3x3 area or flowering a 2x2 in my larger tent
I also had some old led lights that i converted to cobs. I used one driver for each cob. These are in my 4x2 tent. I measured the outputs on one of the drivers and showed .77mA 35v across cob. I dont understand why driver is 1.2a and only putting out .77mA?
My big question is this: I know I can put another cob on these drivers. Should I run four cobs instead of two on the little lights. I know there is a photon:heat ratio thing but from all my watching/reading I am really confused. It would seem to me one more cob in the 4x2 tent for a total of five would be more than enough for flowering. How much would it help to add two more cobs to each driver or how much would it hurt to pull a driver and just have one driver run two cobs for each light?
I am still pretty much a noob in the growing and lighting dept so any advice and input from you guys would give me would be greatly appreciated
