The cathode ray tube in the ESL bulb does not emit X-rays. Unlike in a regular TV tube, the electron beam does not need to be focused. This allows the electron beam to have a lower voltage (about 5000 volts in this case), and so any X-rays produced are much "softer" and easily absorbed by the...

ESL technology supposedly emits light with a "softer" quality than LED or CFL, and this bears out if we look at the spectral graph. This does not have to do with CRI, by the way. I have tried the latest 95 CRI LED, and while it has good color rendering, there is also still something about the...
