1. The primaries are red, green, and blue
2. Fluorescent lamps can dim- usually better than LEDs
3. "avoid light at night" is a generalized statement and not true for everyone
Yes, light all night has been linked to breast cancer in shift workers, but people with a less-than-24 hour cycle need light at night to extent their circadian clock each day
4. Everyone's circadian clock is different, we all need to adjust daily to entrain with a 24 hour cycle
5. Moderate amounts of blue light is not hazardous for people
6. Bright light (and certain spectra) is what suppresses melatonin, when exposed at specific times of day
7. Saying "visible light" is redundant. The definition of light is the visible spectrum
8. UV is not light. IR is not light. These wavelengths fall outside the visible spectrum.
9. You can stop taking melatonin and get smart about your light exposure to allow your body to produce melatonin when needed.
10. Commercial spaces are leveraging the lighting grid to collect data, communicate in case of emergency, and adapt based on occupant's preference.
