I emailed Meijiu asking if the boards I ordered were genuine LM561C S6 diodes because there was some skepticism among us and this is the response I was given...

please don't worry,i can promise our pcb board is certainly real samsung lm561c s6 diodes,

please kindly check attached led diodes test report,

we sold it in such a lower price just because it's on promotional lately,

and we want to build a friendly relationship with our customers in first cooperation,nearly no profits,

please kindly understand,and our price will adjust in next days,but won't be so high as US,i'll let you know once it's finished,

so please trust me,we never think it's wise to deceive our customers if we want a long-term developing.

I have just finished a very bad experience with Meijiu Led. They send DIY kit without connectors, screws, malfunctioning external plastic dimmer - which was priced at 14$ without being asked, very poor communication and not willing to negotiate the reinbursment of their mistake. I managed to get the money back thru alibaba trade assurance, but the nerves, the delay spent wont compensate the cheap price you get there. As more people say and i wouldnt listen, i wouldnt buy again...maybe except pcb, or individual components, nothing assembled there in terms of tech is worth buying... So guys, beware of Meijiu, you might get 1 of 3 complete orders. Dont waste your time and value on cheap things, your brainjuice and health worth more...

Keep selling your cookie sheet light bro. I wont believe it till I see proof from your own 3rd party tester.

To each their own, I bought from Meijiu 2x260w kits and I had them in 3 days at less than half the price of the HLG, they even wrote back to check if the boards arrived and if I'm happy with them.

it happened to me once as well.... fast shipping, good feedback....but as for the long term, thats where the issue is...

Anyone have any idea how far from the seedling should I keep the QB 260W? My seedling just popped out of the rapid rooter and I have it at 60cm and 50% power.

in my experience, i used the same board 3500k at around 75-80 cm above 8 seedlings circled in 3l pots for the first 3 weeks. Added extra board and transplanted them super healty and happy. So, it worked for me i guess

Not my product. Looks like cheapo Mufue knockoffs. He calls them Quantum Boards FWIW. Better call the Ebay police.

Look at your original post. That's not the link you posted: https://www.ebay.com/itm/Quantum-board-24v-3500k-50w-Samsung-lm561c-led-96-diode-sun-strip-90cri/173347662878

Neither link is to genuine SolStrip products. Those products are currently only available at https://solstrip.com or https://solstrips.co.uk/. But haters gonna hate, disbelievers gonna disbelieve.

More third party testing, with a few SolStix racks ....

I said 3rd party TEST. not grows. Lets see some actual data proving they are real. Not images of your buddies grow room. And lets see the ones you paid for, not from the Alibaba dude.
I posted the wrong link, shoot me.
Ive contacted the guy on ebay selling the solstrip, and he said he bought them from you. It has your logo on it.

Maybe he did, its a free market. Anybody can buy a few SolStrips and resell them on Ebay if they want. I think that's what Ebay is for? Or, maybe he posted a picture of a SolStrip and is delivering the knockoffs you first linked to. That's what I mean, they are not authorized to sell genuine SolStrip products. Those are only available at Solstrip.com or our UK distributor, SolStrips.co.uk .

Those pictures aren't from friends. They are from customers. You can read their full grow threads here:

claiming they are S6 bin in the description when the label quite clearly says S3
Click to expand...
Samsung's 90 CRI LM561C chips are all S3 bin, their S6 bin chips are 80 CRI only. Genuine SolStrips use S6 bin, 80 CRI LM561C's exclusively.
