Very interested of these boards, especially how hard you can run them without heatsink.
The ease of the fotop boards has got me hooked
Also, what are the dimensions on these boards?
Unfortunately we never had time to do a like for like test, we had a lot to setup with little time. The lm301b boards were run at about 250w with a 3mm alu sheet backing and didnt run very hot. 3 over 2x1m with decent cover.Have you already tested your lm301b board?
So would I... But im not equipped with the skills or the time to build everything...15$ for that board
Thats realy für prices you paid
Awsome
I wolud take 10 for 150
Anyone buy from Kingbrite
They had quantum boards rn cant beat the price.

Jerry Meng is sound, lots of people have ordered from him.
Its this real Samsung lm561c ? Good light or not?
Jerry Kingbrite has been a trusted seller on alibaba for some years but i couldnt say anything about his qbs. Although, they arent that cheap, i think i paid 20us$ per board for 304 qbs in my last order from meijiu.Anyone buy from Kingbrite

Did you try them yet without heatsink? Or does 70w number come from the seller?The board can run at 70watt without heatsink, if with heatsink, it can be run at 150watt, if the heatsink is good enough, the boards can run at 240watt.
70watt, the input voltage is 42-48V@1600mA, with heatsink, then run at 150watt, the voltage is 42-50V@3200mA.
Dimensions are

at 70watt, HLG-80H no heatsink and with heatsink, HLG-185H, maybe HLG240.
512 diodes total
352 samsung lm561c
I'm sure only a lunatic would want to run these boards at 240 watts but hey, if it floats yer boat, why not?
70 - 100 watts per board will probably suit me better.
After all a QB and GG Board can throw out a powerful amount of photons at 70~ watts.
That's from the vendor.Did you try them yet without heatsink? Or does 70w number come from the seller?
Looks veeeery nice and likely to end up on the list of things to try out. Very interested in any info on this.
Rough calculations of surface area, 1 fotop almost = 4 R2T boards. 4x70=280w, and the fotop i wouldnt wouldnt run harder than 200 with no heatsink. So maybe a bit high. But still mighty nice lookingThat's from the vendor.
I think a bit of testing is required.
it was actually 1200 for the order, i spent around 1400 all together with the frames, wiring, hangers ect.What all did you get for that much?
What kind of temps are they running at? Trying to see if its worth running these bare with no heatsink.I've got a few of the same R2T boards that you have bought, Moflow. Running 4 of them @ 90W-ish each, together with 8 CXB3590's @ 28W each.
The heatsinks weren't ready when I ordered my boards, so I had to improvise. They are mounted on 5mm alu plates, with u-profile alu bars on the top for extra surface area. I'll grab a better pic next time I'm down there.
Depends on what space you want to cover and what much height you have. At 240 watts each i would at least use someone alusheet backing.Question.
How would you guys run 2 EA QB960 with LM301B's? They both max out at 480w.
Without heatsinks they shouldn't run more than half power, so total 480w. Not even sure where to find a heatsink for these that will allow to run higher or if I even should?
Should I use 2 x 480w driver's or 1 x 600w driver?
