Incorporating Reds Into 18 COB Set-Up?

I'm in the process of building the frame work for three 300W six COB DIY kits from Dan and Timber Grow. I don't think I "need" anything else but it would be remiss of me not to incorporate some Reds and Blues now instead of later.
I could use some imput on what to use that rates but won't break the bank and will still fill the void. I'm trying to envision how I would hardwire a few sockets of one sort or another on a frame that's adjustable for height. Would you just run 3 wire 12 gauge outdoor rated romex to work boxes built into the frame? I guess you don't raise or lower your hanging frame often enough to stress romex. TY

I used old computer cord with the female end that plug into the computer made a rectangle cut out of metal electric box drilled for the holes and use the same screws and nuts that the computer had wired that end to the drivers along with grounding the frame and everything else then just plug it in wall and done or at the box you can add a switch to turn it on or off some one on here I seen put a swtch/receptical witch I thought was a great idea I just used a toggle switch

I gotta think more like MacGyver bseeds..
So... you fished the female end into a work boxes and cut a hole to mount it to a blank face plate with the hardware from the computer? That comp cable sure would have more than enough flexibility.
TY bud. Sometimes I get stoned.

no I used one of the holes I think it was one of the 3/4 holes in the electrical metal work boxes cut it out rectangle to fit the computer female plug I hope you understand me what im thinking and what im finger pecking not always the same if you look at some of the new lights and computer they have those plugs this way if you ever want to move your light no problem

theres an led section on these forums , id suggest trying to start a thread there you might get more help.
