Figured this would be fun, since we had a backlight thread.
Here is my setup, up firing lamp to left of display. I was running a 9 watt CFL (40 watt equivalent), but Ive changed to a 7 watt (equals 25 watts). Me like.
As you can see in the image, the only windows I have to deal with during the day is the one with blinds, and the glass back door. Not too bad.
