Good to know. I wasn’t even aware such a tape existed when I covered some powerful blue leds that were interfering with my sleep. Sometimes I wonder if the correct leds are used for status leds. The blue LEDs Im talking about were lighting up a whole wall at night and from somewhat useful they turned to a nuisance of sorts.

Blue leds are an obviously incorrect choice; they are only used because are novel and trendy (well, I guess they used to be novel and trendy, anyway). Human color vision is the least sensitive to blue light – but human low-light vision is the most sensitive to it!

As someone who is red/green colour blind, I disagree that they are an incorrect choice.

Annoying at night yes. But wherever they are used I can finally make out the difference between an ok/nok status.

Ah, I’m red/green blind too but most blue leds in electronics don’t seem to have a status function beyond "on/off", they’re there just to look futuristic.

Yeah my phone charger has a super bright blue led in it. It's kept in a draw at night as the entire room lights up. I keep meaning to cut out the led.

[adgjlsfhk1]

my best guess for blue lights is that it's one of the ones with higher energy efficiency and red/yellow would indicate problems.

One of my HP switches have setting for that, you can choose a time interval when the lights should be dimmed or turned off.

Thankfully the era of "slap blue led so the hardware looks modern" is over (back then blue leds were new thing and pretty expensive), but some devices still go too bright.

Status LEDs should be only bright enough to be obvious, they should be frosted/opaque, and should only be Red, Orange, Yellow, or Green.

Retina searing water-clear blue and violet LEDS have no business being used for any status light anywhere. Even in bright light, the better choice would be bright green due to the eye's sensitivity being maximum in the green.
