White LED lies: It's great, but Nobel physics prize-winning great?

Re: @ scatter

I have two LED lights as hall lights, and what makes the difference is that they have a motion sensor, so there's no groping for the light switch. They also take account of ambient light level. The usual pattern for electronics is a long life, with an initial risk of early failure.

I was already on fluorescents, and colour rendition isn't critical. But this sort of control seems to be quite new, and for a pretty obvious reason. Once you have the voltage for the LEDs, you have to power for the control electronics. The extra expense turns out to be quite small, compared to an ordinary LED. And the end result knocks down the time-domain element of total power consumption.
