2*2in1 QB288 with LM301B and 8pcs Cree XPE660nm
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?

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.

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.
