Which says nothing. How long did they last? And did you compare to normal incandescents in the same appartment? Some places have increased mains voltage that just causes bulbs to burn out faster. BTW a problem that you can avoid with high-quality LEDs. > There were even dark marks on the ceiling from the heat. Well, possibly there was, but the solution to that is CFL or LEDs, not normal incandescents, because those produce even more heat. Halogen are more efficient because they run the filament hotter, but therefore the amount of heat they give off is lower (lower wattage for the same amount of light, plus higher proportion of that is converted to light instead of heat).
