Yeah, you'd want a constant voltage driver for parallel wiring. Your wire should be fine.

Get rid of the terminal blocks and wire the cobs in series.

I'd do an HLG-480H-C2100B for each group of 9 qb120 in series.

Yeah, I rather not risk it myself for a dozen boards. HLG can make a few dollars off me. I'm cool with that. Now, if I was looking for hundreds of boards, it'd be a different story.

Here's a 288 straight from HLG

I'm down! #teamvault

Awesome!

Yeah, the rotators will be pretty beefy. Using 1" stuff. Not going with my prototype slip ring commutator though. Gonna use prepackaged ones marketed for wind turbines and such.

I'm in the process of fabbing up a couple for my main room, using parts from my other one. The drive anyway... lol

I have two actually... Had em for over 25 years. Don't remember who I bought them from. I think it was a place called Hamilton Technologies. One of the companies that had ads in High Times way back when...

Sent an inquiry through the site about the 3M adhesive you guys recommend for the Ledil optics. Maybe you could just post the part number here for everyone. I used arctic alumina. It works, but kinda a PITA to do more than a few lenses at a time... Some 304s with 60 degree Along with a couple...

The driver's efficiency rating. How well it converts power. I'm not the authority on this stuff either. Just a good general grasp...

Not real efficient drivers, but if that's all you've got to work with, might as well roll with it...

lol Well, now I can like stuff

I don't post enough here to be able "like" yet, but yeah it'll fire up.

Yeah it will. I have several similar drivers. A single 1212 will run fine.

Was 18 when I ordered 2. 2 left after, which you got. Craziness...

3000k 304s sold out in a flash! Glad I got mine!

Just grabbed 8 :cool: Waiting for them 304s now... And slate 2s

Long time smoker ... first time poster (just found this place). Looks cool here. Imma chill out and lurk for a bit. Might and some stupidity now and then. -Ken
