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...

thanks man I will look it to it

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.

thanks for your time first of all
I cheaked them out but its looks like its too good to be true ,pretty sure that's the 410.6(umol/m2/s) its total bs... but im not expert
is there any one that tested it ?

about the diods is there any way to confurm that its realy sumsung? and do u have any info about the bins?

mybe should i go with something more proven like the boards???


just small remainder thet the goal is about 40+ mol per day under 500$ if its posibal

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.
