You can’t beat the prices, really. I think these are even better... $164 for lm301b with a 660nm red strip.
This is what I picked up, but with separate heat sinks.
Pictures of fake boards and drivers please?

Thanks for sharing your account man.
Looks like you just missed the decimal points on the diode sizes. The Samsung LM301B/H are 3.0mmx3.0mm. If your lights came with LM281B+ they are 2.8mmx3.5mm.

looks to me the offered light use epistar for the monos, thats not the best.
for UV they state epistar, for the red they dont state anything.
guess if they use cree or osram they would write it.
wont buy for that reason alone.

If you are looking to buy a light, authentic LM301B/H diodes are significantly more efficient than the older LM281B+ diodes.

I'm not looking to buy. Just learn. I just found it interesting that this seller sells most of their models with either 301's, 281's or Epi. Prices are great for someone looking to get into leds IMO
Thanks bro.Here is a non mobile link.

They would indeed. They offer Cree and Osram on some of their other boards with a slight price bump. The ones I purchased were Epistar for 660nm and were listed as such so if they don’t list the LED manufacturer then it’s probably nothing to write home about.
Just spoke to the seller for over half hour. He’s offering a 2 year warranty on boards and driver. Not that I’m sure that’s really worth anything?
He seemed very knowledgable and answered every question I had. Guaranteed that they would be LM301H LEDs.
Admitted they were from China but said he spent months researching suppliers.

I think he might have even mentioned Meijiu? He did tell me who his supplier was.
In the U.K. we get hit with import duty, then 20% vat on the cost of the items and shipping.
If his 2 year warranty is worth anything it’s probably worth the extra £70, and I avoid having them shipped to my address.
I was thinking the risk was decreased. He’s local and i have his number.
Seems like he’s looking to scale up. He said he has been talking to a company about producing his own boards and is very into micro greens.
To be fair he was knowledgeable and we had a good conversation. I was expecting the complete opposite. The kind of idiot who sells/buys iPhones, iPads etc on gumtree(our craigslist), thinks he’s a gangster, and knows nothing about what he is selling.
