I've never let it go long enough for the light to come on. I let it run on the "fast" setting for 5 minutes, then switched it to "slow" for another 5 minutes, then just watched it until the bouncing back and forth was minimal and then I stop it. By minimal I mean just a few frequencies going up a notch or two, then down a notch or two.
I can't believe how much clearer the sound is. In my book this is a "must audition" piece.
