And in a dark room a 7W nightlight bulb puts out a lot of light.  Around the holidays we often have a single 7W bulb in a couple of windows in a room - once your eyes adjust, it's surprisingly bright.  Imagine what someone from the 1800's would have thought of a 7W bulb!  My point being that we need to consider revising our expectations of power use - and we have the advantage of things like compact fluorescent bulbs.  For like 15W I get 60W equivalent of light.  

BTW - the 6 pack of these bulbs at Home Depot is quite a deal at under $10.  The color temp is pretty good too, and they start a little slow when cold, which is nice in the morning!  I've got at least 24 of them now, too bad they don't have any that fit in the small-base candle sockets of that brightness.

They have ones that will fit candle bulb sockets where I live. I got mine at IKEA. They're more expensive than the regular compact fluorescents though, and they don't look anything like candles.
