- vidarh 13y agoI bought a pack of 400 little round black stickers only for the purpose of covering blue leds... For most of the devices I have with blue leds it takes 2-3 stickers on top of each others to dim them enough for me to still see them but not feel blinded when the light in the room is dimmed..
- alexhawdon 13y agoThey certainly are bright, but the light is a terrible colour for us humans. An Optician friend explained to me that the shorter wavelength of blue light causes it to focus in front of the retina, which is why blue LEDs appear out of focus when you look at them.
