Also, I've noticed that during the transition, when people have a mix of incandescent and LED, they internalize the potential efficiency of the LED, and then use the incandescent bulbs in a similar way. So the incandescent light on the hall table that's more appealing gets left on for longer periods as if it were an LED. I'm guessing this is more common in households with legacy light fixtures and legacy nostalgias, though, and that's its own diminishing set.
