I'm confused. The US also banned incandescent lamps? https://en.wikipedia.org/wiki/Phase-out_of_incandescent_light_bulbs https://en.wikipedia.org/wiki/Phase-out_of_incandescent_ligh... > A ban covering most general service incandescent lamps took effect in the United States in 2023 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.

I wasn't aware of that, interesting, thanks. 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.
