It's actually nice. It's a lot warmer than the CSP 4000K, but not as yellowish as an LH351D 2700K (on a Sofrin HS10). Sorry I don't have any measuring equipment, haha.
"but you can always “reset” and get it back to shiny if you want. (I usually just take a little ketchup and a cloth and wipe it and it will look almost like new)"
I got mine from a local woodworker. Maybe try to check if there's one near you? The advantage is you can pick what type of hardwood you want for the wrist rest.
