I run 4 on a hlg240h-c2100 in parallel, thats 525 mA per board, about 55w per board. Or maybe aabit more as hlg usually have a bit more amps than what they are rated for with no dimmer attached. Cover about a 2x4.

given the "genuine top bin" claim,the price, and the fact they are on alibaba......... I'm willing to bet they are NOT Samsung chips. The problem is, the only way to prove it is to buy one and run tests on it. Spend the money and buy REAL quantum Boards,
And as far as I know, Samsung doesn't do binning. There have been a number of these so called "Samsung" chpped boards running Epistar chips, you know, that same garbage that powers all the chinese burple lights............ but hey, its your money...

@pop22 . That would be too much. Remember qbs in flower need 32 watts per square foot. A 5x5 would be 750-800 watts. When I first got qbs I was shocked by how few watts the plants want from such a perfect spectrum. I have the power to run 1000 watts in a 5x5 but never could get above 700 without light stress. Its just too much

I don't really thing this is any type of hard and fast rule, I am running more than that in a 5x5 right now with zero issues.
I'm flowering with 6 v.2 QB288s at 3000k, 4 v.2 elite 96s, and 4 v.2 mou5 pucks. I can't tell you exact watts, but total capacity is around 1460 watts and they are certainly turned up more than half power.
I think I can get away with more light due to more spread out coverage and fuller spectrum.

@70 watts per board I'd be drawing about 420 watts with 6 boards, but its not about watts, its about PAR. I'n eventually going to run 8 QB 304 @50 watts each to do a vertical scrog, or maybe stick a QB 324 in the middle and do 9 boards.

Actually, you can... Epistar, Samsung, nichia, Osram etc all have different characteristics although they are all 3030 (3mm*3mm) or 3056 diodes. Lm561c are 3056 diodes. You would have to be half retarded to think they were epistars... Think before you talk...
Does epistar even manufacture smd3056 chips? Or even 3030's? I just checked... This is what a Epistar 3030 looks like:
Here's a Samsung 3030:
You can't tell the difference? Really?

Well since im at roughly 83.25 per board, im going to give this driver one more go in the new room before i opt for another 320, I've got a Bubba Kush about 2 weeks into flower. Its under 2 of the 304s.
Its an odd shaped/designed room, but trust me when i say i got the max floorspace i could get with what i had to work with. This is THE final room ill ever have so long as i live here, unless i move out to my shed.
Still have some cleanup and wiring to do and going to make reflective partitions i can set to enclose areas, and also to hang on the edge of my scrog. (Just a temp one there now)
Also have a second area that will be 2x3, but its just a place to set crap right now. Need another light, and have to relocate some electrical. I think I'm just going to order one of the 185w meanwells and Run 3 Quantum board 120s or 132s in it.

I recently ordered 4 of the 3000k v2 qb132 from HLG. They havnt shipped last time I looked but wanted to ask if these would be too much for a 32" x 32" tent for flowering. Currently have hlg100 running for veg looking great so far. Also if has experience with these boards I would love some feedback. Thanks.

Epistar makes a 5730 ..... Osram , Seoul Semi, LG Innotek, Cree, Samsung, Lumileds, Everlight, Edison, and several more make 5630 LEDs. Samsung makes 4 versions of 5630 alone not counting binning. You could literally get 25-50 different LEDs that are 5630 on a board. LG looks very similar to Samsung.... That's as far as it goes.... Looks similar. I would only pay with PayPal if buying overseas and then I would find a way to check the output vs known products. At least if they pull the ol switch-a-roo you can get your money back......

It will be full of light...... Maybe dim the HLG -240H-C1750 down to 225 actual watts and you'll be banking in that space.

Thanks boss appreciate it. The hlg100 is amazing so far. Cant wait to get the new 132s

Can you post a photo of a lm301b top bin vs your 301b's?

As far as real lm301bs they all look the same. You can't really tell a difference as far as bin goes. I can post a pic of our lm301b on the boards produced for us by Samsung. I can also post a 6500k on the new horticulture strip made by Samsung.

I can see different kelvin tick boxes on the strip. Does this mean they will be produced with different base colours? They are pretty much useless with 6500k.

I ordered the HLG-240H-C1750A. Is this going to work just fine? From what I understand the type A drivers have a screw to reduce power to the boards on the driver and the type B allows you to install one? I hope the type A will work as I want to do as little wiring as I can on this first one Haha also wire in series correct?

I run mine @ 142w/QB304+. (4) in a 4'x4'. (2) 320h 2800a drivers, QBs wired in parallel. Have to keep lights 16-20" away but spread is pretty good at that height.
Only 1 driver pictured...
*I have fans that I gorilla glued ontop of the heatsinks to keep temps under 115°F. The 12v PS running my fans powers the meter. Duct tape plugs are QBs, white plugs are fans.
They were bright enough to the point that the E27 lights were more or less just in the way, next time it'll be only QBs...
EDIT: if you buy from Alibaba know that you are trading some ambiguity in chip quality for a price cut. You won't get your money back from them without paying out of pocket for an independent lab test, and the time given to provide results of such a test is too short to even send them out. I didn't even hear back from a lab until a week or so after I reached out. The lights work, but are they s6 as they garuntee??? Don't go into the purchase thinking that you can buy comparison chips from other trusted suppliers to validate chip model, no matter how zoomed in, or striking the similarity or difference, trade assurance will not honor such comparisons as proof.

They use a cheaper, thinner pcb also. Run one next to a real QB without a heatsink @ say 60 watts and measure the temperature.
You get what you pay for when you deal with cheapass imitations.
@Stephenj37826 , thank you for the info on the leds. People seem to forget these are the same "merchants" that sell "1800"watt Double Chip!... burple lights that draw an actual 180 watts and have wires ducttaped instead of soldered......
