That's a curious take. I'm not sure I'd trust myself to actually wake up, though I guess I could keep the sound-based alarm as a backup until I was sure. I've also got young kids and occasionally have a *really* short night of sleep, which again makes me think I might sleep though light on bad days.
It's certainly not quite as efficient on the power side of the spectrum, but I'd guess not bad if it's just a few minutes. How do you tell the alarm "okay, turn off now, I'm up"? Just set the timer for x minutes and assume it'll be enough?
