I found this lights, to be in a class by themselves.

Very pure light with no noticeable flicker. Note that the 2400K version is quite a bit warmer than standard incandescents. It will bring out orange/red tones in brown wood.

I took measurements with a spectrometer and get these results:
CCT: 2342K
DUV: -0.0032
CRI (Ra): 96.0
R9: 81.9
Rf: 93
Rg: 102
Blue Peak: 0.23

Normally at this warm of a color temperature, everything looks yellowish. However, because of the negative DUV, which brings the tint below the black body locus towards pink/red it actually doesn't make things look yellowish. In comparison, I bought a 2200K 98+ CRI from Amazon and it had slightly better CRI and R values but because it had a DUV of +0.0028, everything looked nasty yellow. I couldn't use it anywhere.

My test results also shows this LED emits very little blue light, maybe just a tad bit more than an incandescent, which is real good for LED emitters. This means it will have minimal disruption to melatonin production and perfect for sleep.

This light is better than the Soraa series bulb because of the negative DUV. Soraa has a neutral DUV, which is not bad but not my preference. Also Soraa bulbs measure higher violet wavelength peak, which I'm not sure is healthy because violet is higher energy than blue.

This bulb is also better than the GE Relax bulbs because the GE Relax has a positive DUV making things look yellowish.

Waveform should make a brighter version of this bulb.

Colors look rich and natural in this light. Dims nicely without looking gray. Would like a frosted bulb option to be available as the LED “filaments” cast some patterns inside the fixture’s shade, but it is a minor issue for me. I am very satisfied with the quality of the light, having none of that greenish color that comes from most LEDs and CFLs.

Perfect for wherever gentle nighttime light is needed. Ideally for a bedroom but the reading corner is also good. Highly recommended. Nothing like it.
