Definitely! That's where I want to take the series, to talk about the modern health, safety, quality of light, and light pollution concerns. So I appreciate that feedback.
Regarding 5000K fluorescent vs. LED, actually the fluorescent will be way more spiky, with multiple spikes. A typical daylight LED spectrum is a spike around 450 nm, then a drop, then the rest of the colors from green to red.
[0] compares some different spectra, although most modern 5000K LEDs will tend to be a bit higher in the red area. I would say the warm white LED, cool white LED, and daylight spectra are a bit exaggerated/too ideal in this comparison.
What emits most of the visible light in fluorescent vs. LED is actually almost the same thing: a phosphor that converts UV (fluorescent) or blue (LED) into white light. But the actual chemical makeup differs between LED and fluorescent.
There are some new LED technologies that flatten out the spectrum. These typically employ a violet pump (around 415 nm) or some combination of violet, blue, and cyan (around 490 nm). But it's the phosphor engineering that actually does most of the flattening. We're only just starting to see these become available in finished products, however.
