The power draw from a single LED is nearly negligible. If it’s a heating appliance, for example, it’s several magnitudes more wasteful to turn it on, just to see if it heats properly. Even with other electronics the LED quickly tests functionality with almost zero power without having to power up the entire system which would use a ton of energy, since it assumes it is about to be used for its purpose.
