From personal experience, I can tell you that I wasn't as anal about turning off lights in unoccupied rooms after switching to lower wattage bulbs. If someone left a light on in the basement, I'd figure it wasn't worth the extra trip down the stairs to turn it off -- especially if that light burning 24x7 only cost me a buck a month. Although as a counterpoint, after getting a hybrid car, I'm not really making extra trips, even though it is saving me about $150 a month in gas. But that is more due to time budget than anything else.
