I understood he was referring to incandescent light bulbs, which have been largely regulated out of the market. So you now need to get an "Edison light bulb" which circumvenes regulation but costs significantly more.

So you can't even buy them in the US anymore, either. And cheap LEDs are available everywhere, with many color temperatures to choose from.

Light temperature is one thing, but the spectrum is very different (which is essentially how it saves energy, almost all radiation emitted is a narrow band of visible light whereas an incandescent lamp produces a blackbody spectrum with a lot of radiation emitted in the infrared).

Also I notice a lot of color banding (not sure if that's the right term) with many cheap LEDs. I observe the same or at least a very similar phenomenon when watching DLP cinema projections.

The problem here is that they tell you: - We're building renewables which deliver super clean and cheap energy - CO2 is the root of all evil

Then, they force you to use an LED which uses less energy (which is clean and cheap, no?) but contains a lot more chemicals and rare earths, so in a number of ways seems less "environmentally friendly". This seems contradictory and half-assed.
