Ok so right now I have a 315 cmh in there but wanna put that back in my big flower room an build a cob big enough to do my whole tent, kinda on a budget gonna either use the citizen 1212 or the 1217 I think is the next one up I have a mars reflector 96 an a mars 700 I can use for parts, I DONT want to rebuild the mars lights I wanna build a new frame an use the drivers an heatsinks from the mars lights, an upgrade the drivers later on when I get more cash, the little reflector is hanging in the big room for side lighting still so haven't ripped it apart yet, the 700 has 7 drivers an I'm assuming the other one prolly has 3 or 4 , there's nothin written on the driver's not sure how much they will power.. will 1 driver power 2 citizen 1212's? I've read a ton of stuff I've been to the mars thread an watched the videos, still don't really get it how to wire it all together.. also should I use the fans that are in the mars or make it passive heatsinks? Should I buy diff heatsinks or add to what I got I'll pop the reflector open if I need to
