Hello

i have bought some generic IR LED for illumination, i  forgot to ask of the exact code to check theri datasheet,
and wondering whats the general max power they work.
i found datasheet from 50 - to hundreds of mA, and i am confused !

i.e. LED are 20-25mA in general

Without a part number or datasheet there's no way of knowing.

Generally infra red LEDs have a higher current rating than visible LEDs because their forward voltage is lower (1.1V to 2.5V, as opposed to 1.8V to 4.5V) and the maximum rated power dissipation is similar.
