I think the seller mixed things up, cause I brought the two versions, the natural white 5000K and the cool white 5900-6500k, and the cool white showed a terrible green tint, but the 5000K showed a 6500K perfectly white light, with little green at lower current, and the green completely vanished at high current, so, based on this, i think that the seller got confused when making the product page on AliExpress.
That’s the test i made of the ‘cool white’
That’s the test i made of the ‘natural white’
User u/minkus1000 also noticed it. His post about this LED.
