We make the led boards with 288pcs Samsung 301B and 8pcs Cree XPE 660nm. the input voltage is 48-56V/2100mA, but seems when we put the 3500Kevin SK top bin, the spectrum graph just a little different than pure 3500kevin, Is this correct?

Your CCT is over 4000, so it would seem you're not using 3500K diodes, which then creates doubts you're even using 301B's. The board has 4000K checked, so why would you mention 3500K?

oh, yeah, you catch me, we tested 4000kevin and 3500kevin, here are the 3500kevin

There is a lot of interest towards these types of products in forums. The biggest problem seems to be that people often don't get what they ordered. It's quite a pity. Certainly there are opportunities for any supplier who would want to earn a reliable position.

Naturally the first step is getting the product right, but after that communication plays a very important role. Because many people feel cheated, even small mistakes or problems can drive customers away. If you work for R2T I am sure you could get a lot of good advise from people here. In this forum people are much more polite then other places.

The problem is proving your diodes original since a lot of people buying QBs from China got scammed...

Stable supply of products claimed would create a reputation, that would last until abused.

I have not seen the shop involved, but I imagine I am not the only one who would appreciate clear product placement and pricing on the site too. Tax issues are marginal compared to basic trust. All the product pages end up trying to cover the companies range of products and prices, so finally you cannot learn anything without taking contact. It's quite confusing - which really does not help any honest party involved.

I’d like to test these against my QB288 v2s to see how they stack up.

That would be really useful

Hi Guys, you know for growing the Cannabis is not allowed, so, we are waiting for ours client's feed back. hope everything is good for the boards.
by the way, we will have a new big product samples finish, really a 1000watt with LM301B, still with Cree XPE as a option. hope you will like it!
any question, please email me: [email protected]
