PRODUCT REVIEW
Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb
★★★★★
Very good photometric results and lovely tint
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."
