for me, i am a long time user of cheap led 4x18650 bike lights, which have always been cool/blue/with purple fringe, at best, and CRI really doesn;t excite me
i;m happy enough just to have any bright cheap light that lasts 3-4 hours over 700 lumens
and lasts over 4 years, costs under $35
(compared to incandescent+nicad, anything modern is WAY better)
