I use mostly LED bulbs, but isn’t it true that LED bulbs all have a lot more blue in their spectrum than incandescent, even the warm ones?[1] I understand why people prefer incandescents but I really prefer my lights to be as white and bright as possible and so I’ve always bought LED bulbs.

It's pretty trivial to find a warm LED [1], just look for something with a temperature of 2700K or lower and you are set. In fact, I have a bulb with that color from about that time still operating today.

- fiddlerwoaroof 3y agoI couldn’t find the post, but there was a more recent post (I think it reached the hacker news front page) about how just about every LED bulb has significant blue emissions.
- cogman10 3y agoEvery "white" light has blue emissions (blue is, after all, part of white). Blue is visible, the LED blue emissions for a 2700K bulb are no more or less than the emissions from an incandescent.
