Um, no. Only the low power per LED filament ones are better.
I regularly examine this stuff, also being scientifically trained and having been a design engineer, broadcast engineer and photographer, I know how this stuff ACTUALLY works, I do not go by the adverts.
Also less UV makes the colour WORSE.
The point is to convert the UV to visible light with the phosphor. Decent CFL and LED do not actually radiate UV.
Obviously daylight fades artwork. Decent LED, CFL, Florescent and halogen lamps for art display have UV filters.
The colour rendition problem is worst with the COB and similar LEDs (the one to nine high power types) and highest efficiency CFLs as well as higher efficiency LEDs.
I do think the idea of mixed colour LEDs so as to be able to have a less blue front light (as per some Kobos) is a good one as the evidence suggests the excess blue (WORSE in LEDs with LESS UV) is bad for sleep and degrades the retina.
So I don't use the fixed "white" front lights on my PW3 or Kobo H2O if there is any alternative. I have good enough lights to read old books, so never need front light on at home.
