@Siph I just think blue is a very bad color for power indicators on like power strips that might be plugged in in a bedroom where someone's trying to sleep

@Siph @Felthry those are just blue LEDs that pretend they're not :P except the ones with phosphorus I guess

@noiob @Siph what do you mean the ones with phosphorus? I don't think you can make a white LED using a phosphide semiconductor, their bandgap is too low
-F

@noiob @Siph and if you mean the ones that have a phosphor (unrelated to phosphorus) but those are the ones you say "are blue LEDs that pretend they're not"
-F

@noiob @Siph (the phosphor is cerium-doped YAG which contains no phosphorus as far as we know)

@Felthry @Siph oh lol it's the same word in German

@noiob @Siph oh! that's interesting.

Phosphorus the element is commonly used in other types of LEDs so i thought you might've meant that; InGaAlP, GaAlP, InGaP, all these weird III-V semiconductors are common in red, yellow, orange, and green LEDs but you have to move to InGaN, GaAlN, and other nitride semiconductors for blue, violet, and UV ones
-F

@noiob @Siph and of course any white LED has to contain blue light and you can't (efficiently, anyway) upconvert longer wavelengths to shorter, so you have to start with blue, violet, or UV in order to get white LEDs
