I get the impression the writer's opinions are extremely niche. In the case of blue pumped LEDs he's referring to bulbs that use a short wavelength LED in combination with phosphor that absorbs the light and reemits it at lower, and broader, wavelengths. So long as the desired CRI and color temp is being produced, I'm not seeing the issue with method to get there.

This was part of my suspicion, but I'm not familiar enough to know if that was correct. > I get the impression the writer's opinions are extremely niche. I'll be the first to say "citation needed" to what I'm about to say, but I feel like we went through a cycle of "the science is clear: blue light is bad for sleep!" to "actually a lot of that was not good science", so I'm unclear of where the consensus actually is (if I ignore this article).
- wrp 3y agoIf blue pumped LEDs rely on short wavelength emitters and phosphor excitation, how similar is the light spectrum to that of fluorescent lamps? As you may know, fluorescent lights are not used in museums because the UV light from them damages things. Incandescent lights were used for a long time, but I've been told that now LEDs are recommended because the emission spectrum is sufficiently safe. I'm wondering if blue pumped LEDs will cause a reversion.
