I have the 5000K V2 in a few S2+'s and a M1. the S2’s have pebbled TIR’s in them. I don’t notice a bunch of nasty tint shift in them. No, the CRI isn’t there but they are lights just sitting around the house for the wife and kids. Looking in dark closets and whatnot.
I also have them in a first gen FF E07. I wish I new what the output was with the original meters and had a way to measure the output now but, it looks to be a bit brighter. That could be my eyes playing tricks on me.
Someone who just wants a light and not worried about all the numbers it’s okay at best. It’s been a few years since I looked at the spec sheet on it. I think I remember it being pretty efficient in lower light levels. Less than 500lm.
