Only spare bead LEDs are available on Amazon. If you want bead LED strips, those are available on Adafruit.I just saw these very very little LEDs.
I always see the little LEDs on a wire with a Battery Pack called string LEDs.
These are like Bead LEDs can anybody tell me where I can Buy just the Bead LEDs?
mcd is the abbreviation for millicandela, µcd (or even ucd) is for mircocandela. This is a difference of three orders of magnitude, that is, 1000 times! While 2mcd is not very bright, it is a 1000 times brighter than 2µcd.2mcd (2 micro candelas) is very low light output, not very bright. max power rating is do not exceed 4mW and it is old technology.
Because he does not seem to get it that the current rating is a maximum, not a requirement, and that running a 20mA LED at lower current, like 2mA, is fine and will produce about 1/10 the rated output (mcd.)am not sure why @biferi is looking for LEDs when he has perfectly good ones already that just need appropriate current limiting resistor(s).
