What really bugs me is the many indoor lights in our world that are not (or cannot be) dimmed in the evening/nighttime. Especially at this time of year when much of the US is dark at 5pm, it gets pretty unbearable being in an office, or on public transport, at 7pm which is still lit as if it were noon.

What I would love is to see more intelligent lightning systems that use the current time and location (easy, given most lightning is fixed) to automatically dim a certain amount depending on the time of day, much like the F.lux app [1].

And don't forget redshift[0]! It needs some more open source love :)

DOE says 14% of homes have dimmers in the US, and the dimmer was invented more than 50 years ago.

Another issue is not all CFL and LED bulbs are dimmable. So if you had a dimmable incandescent bulb and replaced it with early CFLs or LEDs they were not always dimmable (and I think cost more?) andin some cases you have to buy a CFL/LED compatible dimmer.
