Water Cooled Lamp Update and Maybe a New One
Gotta finish up the center section of the lamp! Between political bun fights here, life, individual teaching practice, etc, I'm time short.
Got the COBs on and pigtails soldered, just gotta wire up the COBs, flip it over and redo the AC side of things and that has been stripped out already. Wiring job won't be first rate cause I'm thinking, Gen 2 cooling bars, if I wanna grow when it's legal. Might have a much better cooling system etc too.
A new water cooled rig would use enclosed 70 watt drivers to run parallel pairs of Citizen COBs, or individual 50 watt enclosed drivers to run them alone (preferred for water cooling). I'd use ideal COB holders too and quality pads or paste. A three bar Gen 2, 6' long should do the job, 18 COBs running at 50 watts each + driver (10%) = 990 watts, or around a 1 KW with a COB spacing of 12" length wise and maybe ten inches width wise. I'll alternate the COB spacing on the inside bar for better coverage. Hang it high and run the COBs at 50 watts with holders and reflectors. What I got now would work fine, but I might want a project before the next legal grow. Not against the law to build water cooled grow lights! I can build the lamp rig outta 2 x 20' aluminum extrusions (standard lengths) and some 1" aluminum angle, to hold it together. I got some thermal cut off switches and thermal fuses too, Some WAGO connectors would make a neat job. Two zone switching would be nice too to shut down one end of the lamp for single plants. Might give the small 24 x24" water cooled rig away, as is, an awesome tent or single plant grow light light. I'll keep the 6 citizen COBs I was gonna put on it and just make a couple of minor repairs and changes. Might increase the number of COBs on the big Gen2 rig by 3 COBs, one per bar for a total of 21 over 3 bars. Might be a bit hot though and overkill for the grow table. Might try to stick with 1 KW though...
