What is really nifty, is taking a room that normally has six 40 watt incandescent bulbs.
Then replacing those with 32watt dimmable flourescents. Which means a nice light level at minimum power, and the equivalent of a thousand watts incandescent when you crank it up.

Here comes the sun!

Even though its only perhaps 1/50th the brightness of a summer day, its plenty enough to get you the antidepressant effect.
