The Chinese Quantum Board Knock Off Builds

As the title suggest, can people post their builds, current grows, with results and not bullshit. Please don't start shit between HLG and Chinese made boards, every one has their own ideas and budgets and that's fine. This could be just as educational as any other custom builds, lets see how...

Your answers are all here.. Good luck

R2T STRIPS are 3ft or 900mm As you want to cover a 4 x 4 they are the better option.
R2T are one of the better companies on Alibaba
You'd need a MW 480H 54A Driver and 6 + strips for a 4ft x 4ft tent.
The 3pcs Sunbar-3ft in parallelled can be driven by Meanwell HLG-240H-54.

The strips look fairly new so I don't know if anyone has tried and tested them yet.

I call them Disco Boards
I've had these boards below from R2T since October 2018 and have been using them nearly a year and a half now and they preform very well, no diodes out.
I tested them with a multimeter and an apogee par meter.

.
I run them at around 70 watts per board, so very softly and super efficient.



It's just a gamble buying from Alibaba as you can't really tell what binning you are getting.
The newer sun like strips are lm301b diodes. Maybe not Top bin but they'll still grow plants.
