If the tint is noticeably better probably not the same bin then. I know Simon had several for a while (prior to the D4V2) and maybe he is still using up those or got a better batch to more closely compete with the FW3X and MF01 Mini?
When I compare an original fw3a sst-20 4000k, an fw3a with known fd2 bin sst-20 and, original D4v2… this seems to fall between the awful D4v2 and the fd2 bin sst-20.
Slightly too cold tint, light quality is very dull and boring, compared to any higher CRI led from other manufacturers that take illumination quality more seriously. Ok for occasionally lighting up stuff in the dark, unbearable for EDC.
If you asked that question three years ago I really would have liked the led, but so much has happened in led quality the past years (but not at Cree) that it is not so anymore.
I went the same way. True, good old XP-L HI has low CRI, but as I was advised by TK, they sustein the highest output due to least heat production. Bingo for me since in this case I pay much attention to long-term output.
I’m more CRI demanding when it comes to headlights…
