Yeah and the same CFL uses 1/4 of that to give the same light. And lasts about 5 times longer.
Under near-ideal conditions.
In our old place, we were changing every bulb in the house every other month, regardless of what kind of bulb they were. When we first moved in and noticed that half the lights in the place were burnt out (they were all incandescent at the time), we went out and bought CFLs for $3 per bulb at Walmart (the GE energy smart line I think they were, sold in the plastic two packs with the green labels). Within the next month we had replaced the rest of the lights in the apartment, and 2 of the CFLs we had bought initially (one in the bathroom and one in the living room). Two weeks after that the bathroom light went out again (and again 3 weeks after that). After 4 months we had replaced every single bulb, and about half of those had been replaced twice or more. Most I switched back to incandescents because they worked out to be $0.25 a piece and the lighting part of our electric bill didn't remotely compare with the heating part (welcome to winter: Bozeman, MT in a house with poorly sealed single pane windows).
When our refrigerator blew we had a repairman come by and he informed us that the lighting in our house wasn't surge protected (along with about half of the outlets) because there was poor regulation in the area until about 10 years ago, so any houses built before then were built to very widely varying degrees of freedom and safety. I then watched him pull the refrigerator away from the wall and saw that the it was plugged into a 3-2 outlet changer (the ones you screw into the middle screw on the outlet, this one was screwed in) which then went into the wall outlet. He unscrewed it and plugged it into another (two prong) outlet in the kitchen and it turned back on, so he went and looked at what was wrong with the outlet (one of the wires was barely connected). I then watched as he replaced the two pronged outlet with a 3 pronged outlet. As there was only 2 wires in the socket, I asked him how it was grounded. He replied that it wasn't as he pulled out a sharpie and colored a circle around the ground prong, but he had a 3 pronged outlet with him and it was obviously no different than plugging the refrigerator into an adapter into a non-grounded two pronged outlet.
I'd say we spent at least $3 a month on lightbulbs while we lived there. Several of the bulbs we never replaced again when they died. When we looked for a new apartment to move into I brought along my surge protector which has a 3 pronged plug and a couple of lights on it to let me know that A: power is constant without significant spikes or drops and B: the outlet is grounded. The first 10 places we looked at failed both conditions. 4 didn't have any 3 pronged outlets. In 4 that did, the outlets weren't grounded at all. In the others, the first light wouldn't stay on for more than a few seconds. Every one of those places had at least one light bulb out and almost none of the bulbs anywhere were CFLs. On several of the 3 pronged outlets I noticed a black marking around the ground.
The 11th place we looked at passed my very simple test, and since we moved in (8 months ago now) I have replaced 2 bulbs with CFLs (GE smart line), 4 that are on a dimmer and 2 that are outside with new incandescents, bought 2 incandescents and 3 CFLs (GE reveal line) for lamps and have 2 bulbs out which I haven't replaced since moving in (one in a bathroom and one in a hallway). Both outdoor lights are out and one on the dimmer is out (all 3 were new incandescents), but overall I am replacing them at less than 1/4th the rate which I was at the old place (9 blocks away, same electric grid, underground cabling). I am quite happy with the CFLs overall so far and enjoy the color from the reveal line more than the others.
I don't quite understand why 13 bulbs have gone out in the past 8 months, but 10 of them could have been pretty old I guess (leaving only 3 to go out within 6 months of replacing them). Still that feels like a pretty high failure rate considering that my parents replace about one a year and they have more lights in their house than I do.
I will never look into renting an apartment again without my surge protector, even though I do not believe that it is sufficient to everything I need to know. It is certainly capable of weeding out the completely unsuitable places.
