Hi guys, first post I've lurked for a while and decided it was time to join. I wanted to share my fixture and had a couple questions. The COBs are Vero 13s 12 of them 3500k. Not sure what they are running at the drivers says 500-550 mA so I guess somewhere around there. 4 drivers 3 Cobs per driver. No surprise Growmau's video was my inspiration. Only have this one pic for now.
As for my questions..how do I determine things like efficiency and par watts or any other the other technical stuff I see people talking about all the time? I'm mostly just curious how it rates.
I have 2 more power supplies same specs 55-100v. I was thinking about picking up 6 more Cobs and a couple heat sinks from heatsinkusa. 3 per heat sink. What size would I need for passive and active?
Last question, I'm planning on using this mostly for veg in a 36"x20" tent 30 watts per square foot. Is that enough? I heard 30 was about the minimum for all around growing figured it was a bit better if I'm just vegging.
Thanks in advance!
