Yet another factor to consider with incandescent lights. In colder climates, the waste product of incandescent lights is actually useful for a greater portion of the year, depending on how installed and used. Heating an attic with ceiling can lights might not be so useful. Heating a room with a table lamp can be, when cold outside, especially when other forms of heat are more expensive and/or have greater impact. So what will the countries like Iceland, Norway, Sweden, Finland, Estonia, Latvia, and Lithuania, be doing with incandescent lights?
It was also pointed out to me just a few minutes ago that someone found that his generator used more fuel with CFLs compared to the equivalent light level of incandescent. He attributed it to poor power factor of cheap CFLs. Maybe those "better quality" ones would not have this issue.
