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

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?
