I’ve been looking for some good lighting for my editing environment, and came across these bulbs:
Has anyone tried any of their bulbs, and if so what was your experience? Thanks!

Haven’t tried them, but likely to…
Someone had to pay attention to the dearth of full-spectrum illumination.

This guy covered them, and it seems like there are few cases where you’d actually want to bother spending that much extra - https://www.youtube.com/watch?v=XeR2uPPCA2k

I have tested them and have a spectrum graf as well as their CRI/TLCI-values plotted somewhere… My memory says that they are not bad at all, even if I do not call a CRI/TLCI of 95 especially “high” 
(It is actually 93.3.) The red R9 value is bad.
Result is XYZ: 855.285989 786.161339 304.346840, D50 Lab: 214.654474 40.825019 88.637625
Ambient = 786.2 Lux, CCT = 2956K (Duv -0.0004)
Suggested EV @ ISO100 for 786.2 Lux incident light = 8.3
Closest Planckian temperature = 2967K (DE2K -0.8)
Closest Daylight temperature = 2951K (DE2K -2.3)
Color Rendering Index (Ra) = 93.3 [ R9 = 63.2 ]
R1 = 93.3 R2 = 96.9 R3 = 98.9 R4 = 92.6 R5 = 93.2 R6 = 96.2 R7 = 92.3
R8 = 83.2 R9 = 63.2 R10 = 92.2 R11 = 92.9 R12 = 86.1 R13 = 94.2 R14 = 99.3
Television Lighting Consistency Index 2012 (Qa) = 93.5
IES TM-30-15 Rf = 92.01 Rg = 98.44 CCT = 2956 Duv = -0.000367
And here is the spectrum plot:
Have fun!

The use case I worry most is my single-image spectroscope camera profiling. I bought a tunsten-halogen spotlight to do it, and then couldn’t find it for sale anywhere six months later.
Having something that puts out at least some energy across 400-700 nm is essential to my process. And, a corresponding SPD dataset to use in biasing the data.
That guy made a strong case for the Phillips UltraDefinition bulbs being very near in quality for a small fraction of the price. A little poking around (outside of Philips’s useless web site) suggests that they are available in 2700K, 3000K and 5000K variants.
