I'm looking for some replacement Power/Turbo/HDD LEDs, but trying to shop for one led me down a rabbit hole I didn't even know existed. These come in all sorts of angles from 20 degrees to 100 something degrees and strengths of 20mcd to 13000mcd. I don't want to blind myself when I use the computer and I don't want something I can't see in daylight either. What is the standard for these damn things?
