Regarding FFL351A: There is no significant tint lottery, thankfully. BUT there are three different batches.

• First “3700K” was quite rosy,
• Second “3750K” was neutral
• Third “4000K” was very rosy

One more important quote and a question for @14500. I assume “very rosy” is more rosy than “quite rosy”? Sorry my OCD self just have to ask.

Independent of CCT, the tint (of course) has huge effect on a LED’s color rendition, and if you have that second group above with “neutral tint,” I would guess it might be on the green side in comparison. Mine is the third group, listed on the web site as “FFL351A 4000K (Rosy Tint)”.

There is an excellent review of the LED by our own BLF’er @koef3 HERE, and AFAIK (anyone please correct me as needed) this LED belongs to the first group. Koef’s test reported truly top notch CRI numbers, Ra 96, R9 97, CCT 3955, and best of all for tint, Duv -0.0064. There is also a very thorough review of the flashlight by another BLF’er @Sirstinky on 1lumen HERE. I don’t know which group this LED belongs to, but it could also be group 1.
