Im really happy with the outcome of my QB / cob build, I feel inclined to put up a few pictures of the light in action. About 15sq ft. of space. The 4 cobs ( citizen ambers) are being driven at 50%, and the QB 288’s at 75-80% I don’t have any output readings, but the ladies don’t seem to be...

So I ended up going with a mix. 4 QB 288’s v2, driven by two hlg-240h-2100b’s, and 4 amber citizens. The driver recommended to me for the citizens wont even turn them on. A friend of a friend recommended i run them with hlg-120h-36a. I shouldve done my own math on that... they wont even turn on.

Thanks again for the input. Heres a pic pre wiring. I ended up adding in 4 amber citizens.

SCJedi, Thanks for the tip. I've tried to find info on their upcoming release, but Ive not found a word of it. Anymore Info?

Thanks for the response. When you say other newer cobs, are you talking vero, Bridgelux?

You are absolutely right. Thanks

Hey All, I'm new to the forum, and new to the DIY LED Scene. My apologies if this is out of place. I started out looking at building a cob setup, and have started leaning towards QB's. I have no first hand experience with either one. The space I'm flowering in is 2.5' Deep x 6' Wide x 7' tall...
