Quoted from rad:Interesting info - thanks for sharing.
I wonder what the difference would have been if was just idle (not being played)? I would expect a much larger savings.
I measured this for my Bon Voyage (EM). At idle, with incandescents about 100W, with LEDs 25W.
A general rule of thumb that works pretty well for any lights is that an LED will consume about 20-25% of the power of an incandescent of similar output.
