Most people who order off alibaba know they run a big chance of not getting lm561c diodes anyway so your tests would be useless.. paying 30-40$ a board that's 15% less efficient or so is worth it to more than enough people to keep them in business

Agreed.
It's just a shame that white leds are going the same way as blurples with people selling anything to make a profit

It's good to be looking into this new style Samsung. I'd like to know more about it.
The total cost as below:
1pcs grow board, with 200pcs Samsung SMD LED, 120w-----$29
1pcs meanwell HLG-120H-54A/B---$36.1
1pcs heat dissipation----$10
Total samples cost----$75.1
Above all parts shipping cost total: 39.3/pcs by DHL.
Total: $114.4
this is Shenzen Bava ...price is ok
But do I need something else to make it run or this is a kit version...

Their review can say anything they want that dowsnt make it true. I can show u the conversation if u want. And there isnt a huge difference. Maybe 10%

I dont know about bava but ive purchased 4 boards from meiju 3000k for veg and flower for my 4x4 running at 520-530w on 2 hlg-240-c2100b driver (without poti) im about 1 week from harvesting my White widow and so far looks like I should be able to pull easily 1g/w of quality bud probably more.. for about 400usd including shipping.. for a first grow with some newbie error here and there I think thatspretty good so either the lights are real lm561c s6 or not I couldnt care less they did grow very well and met my expectation so far.. ill report back once I have final dry weight - around in 2-3 weeks. I think quality for the price is really there.
On a side not the sales rep from meiju wrote to me yesterday and sent me their list of products with price. I see they have new boards with some epistar 660nm for added red spectrum but also received their compliance document for CE qnd ROHS for what its worth I dont care but maybe some care about that too

I expect you're correct about a lot of these boards having Epistar diodes, but this "black dot are lm561b nonsense" does have some background. I have Samsung Acuity strips with the black dot.

Any pics?
The Mejui Boards are working great for me too. Great coverage - about 12" x 36" per board. I might even consider another 2 later funds permitting.
I'm using 150 watts per 800 leds, probably not lm561c but that's half decent efficiency.

I'd bet my years crop on it.
What I'm saying is a lot of leds have a black dot, even the lm561c, just very faint. People are calling everything with a black dot lm561b withought any testing what's ever.
I bet the alibaba vendors are laughing as now they just say they are lm561b and people belive it.

I must say they look pretty good
Here is some recent pic of my grow (more in my journal)
They are looking very frosty and good size.. could have I achieve better with hlg boards? Maybe maybe not.. but all I know is the girls loved the light .. so at this point dont really care either they are legit lm561c s6 or not.. i could have twice as much boards for the price of one hlg550 for example.. so this is really a no brainer for me.. I encourage people to buy HLG when they can afford but people should not be scared to buy those boards from alibaba as Im getting good result so far.. but I understand different vendors may use different diodes and there is probably even a risk of getting different diodes from the same vendor on separate orders.. but all in all so far im very satisfied
I got the 304boards running each board at 130w (or 260w per heatsink) :
