I went to wikipedia to look up coal gas, which you mentioned in the video but didn't link to:
https://en.wikipedia.org/wiki/Coal_gasMy dad's house was built in the mid-1990's. It has custom fluorescent bulbs that are probably rated at 5000K. They're "okay", but only because the bulbs are entirely hidden on top of cabinets or high in the ceiling, and filtered through the tan paint on the walls. I found some 2200K COB LEDs that I intend to install on those light circuits, as the other lights in his kitchen are a case study in poor lighting practices.
His kitchen has canister lights. The stickers say "max 40w", but he had 75-watt equivalent 5000K CFLs in those canisters. They were terrible. I found a box of 2700K 60-watt equivalent LEDs in his laundry room, and switched them out while he was traveling. At the time he was like, NO I'M OLD I NEED SUPER-BRIGHT LIGHTS, but now he uses those lights instead of ignoring them. They're still too bright, but at least they're usable now. I recently found some 15w and 25w incandescent bulbs: the canister lights directly above the counters would be fine with 25w bulbs.
In your future videos, I'd be interested in comments on the dark-sky movement, efforts to prevent skyglow, how people commonly use too much light at night, and the abandonment of good lighting practices in the name of energy-efficiency: glare, "daylight" LEDs, broad-spectrum streetlights, etc.
OH, and I'd be especially interested in the difference between 5000K fluorescent and supposed-5000K LED bulbs. I'm sure the spectral power distribution of the supposed-5000K LEDs is totally different than 5000K fluorescents: lots of blue with just enough ROYG to trick people into thinking it's 'white' light (LED) vs. a relatively-flat power distribution (fluorescent)?
