I don’t have an incandescent to test but I tested a heat lamp with 100CRI and almost no blue light and 0.000 DUV at 2800K. I think incandescent is similar.
SW45K 219B 9080 has very high blue light intensity. I can’t find a 70CRI 4500K to compare with at the moment but it is definitely not a light to shine directly in your eyes.
I haven’t tried the SW35 yet. I haven’t tried Optisolis 6500K. I never go above 5000K unless it is for a pure thrower. I measured sunlight from 3000K to 5700K depending on time of day. Cloudy day can be 6000K+ but I prefer sunlight over cloudy day.
E21A, 2070K, 95.5 CRI, blue peak intensity of 0.07
E21A, 3061K, 96.2 CRI, blue peak intensity of 0.45
E21A 2x2000K and 2x4000K, 2828K, 94.5 CRI, peak intensity of 0.40
The SST-20, 2910K, 96.9CRI has a blue peak intensity of 0.38
The XP-L2 HD V4 7A, 3168K, 72.1 CRI, blue peak intensity of 0.76 and a DUV of –0.0029 (tint is real good btw).
XP-L HD, 2958K, 70.1 CRI, blue peak intensity of 0.39
XP-E HEW Q3 7A2, 3311K, CRI 89.8, blue peak intensity of 0.57
Nichia 219B 3000K 9080, 3391K, CRI 95.2, blue peak intensity of 0.57
Yuji, 3191K, CRI 96.6, blue peak intensity of 0.060
Optisolis 2700K, measures 2973K, CRI 97.5, blue peak intensity of 0.41
Oslon Square 92 CRI 6X tint, 2746K, CRI 91.3, blue peak intensity of 0.29
Oslon Square 96 CRI 6U tint, 2831K, CRI 95.9, blue peak intensity of 0.26
Oslon Square 92 CRI 5Q tint, 3346K, CRI 94.9, blue peak intensity of 0.61
It’s real hard to quantify blue light. The blue peak intensity above is relative to the rest of the spectrum for that emitter. The actual amount depends on the lumen output also. In order to get a good comparison of blue wavelength, you would have to overlay the graphs, which is too difficult and too much work to do. However, I think the blue peak intensity is a pretty good indicator of how much blue wavelengths is emitted by the emitter for these warm white CCTs.
