LED Blue Light Issues

Do blue LEDs on home electronics bother anyone else at night time as much as it does me? They appear so much brighter to me than other colors

The 'red' cones alone can't tell the difference between orange and brick red. The idea is to stimulate all 3 types of cones and the rods in the same proportion as daylight does. RGB LEDs should have the cones covered; I wonder if the problem are the rods? Do we need 4-component LEDs?

it's totally possible to make leds with similar properties, but it's generally but done because narrow spectrum lighting messes with color perception

Don't LEDs have a similar (or worse) spectral profile?

You’re making assumptions based on a lack of content this article did not set out to provide.There is more to it than color temperature, the frequencies emitted by LEDs can be vastly different even if the light appears the same color. Here’s an article from last year specifically about blue light and retinal damage: <a href="https://www.forbes.com/sites/fionamcmillan/2018/08/11/how-blue-light-damages-cells-in-your-eyes/#387c57c2384b" rel="nofollow"

Absolutely! Thanks for pointing this out — it’s in fact one issue with light sources that are not full-spectrum, like fluorescents and (even “white”) LEDs. They can make objects appear to be different colors!

Keep in mind: all LEDs leak blue light even the warm ones (color is achieved by average so you can have high red and high blue and it looks balanced visually). These bright blue leaking LEDs are great during the day — especially those with high CRI and R9 values. But not at night when you’re trying to go to bed! Switch to incandescent only in the evenings until they figure out blue-less dimmable LEDs

"White" light sources are generally not really white. For example compared to sunlight ordinary light bulbs are a bit orange and fluorescent tubes have a green hue. Our brain mostly ignores these differences, but a camera sensor does not. The author might have turned up the saturation on these images though, I don't know how strong the difference is supposed to look.

The color temperature is not the issue in how fluorescents look. The color issue is that there are a only a few phosphors in the bulb, and so all of the light coming out is at just a few discrete wavelengths. An incandescent produces a smooth combination of all wavelengths in the visible range. The light from a fluorescent looks like the right color on a white surface, but many dyes reflect specific wavelengths of light. This means that colors under even good fluorescent lights look differen

Same here but maybe it's simply a case the filtering out blue reduces the total light intensity enough to be easier on the eyes. Wonder if similar results could be accomplished by filtering red instead or simply turning down the brightness on our devices and using lower lumen bulbs around the house.
