Very nice neutral colour. I don't have a spectrometer, so I can't tell how accurate it is, but looks like 5000 K to me. The colour rendering is also very good. I checked the spectrum with a diffraction grating, and it is nicely continuos. The led came in a big box, I was really surprised.
The light output is not as much as claimed, which is 1500-1800 lm on the packaging. I compared it to a BLF A6 with XP-L emitter @ 1A, which is cca. 1000 lm and it is only slightly stronger, so around 1100 lm.
