John, if I recall that previous discussion, the point was made that although the fan almost immediately stopped when a power failure occurred, so did the bulb. No additional heat would be added to increase the temperature, and although the bulb would take longer to cool down by convection, it wouldn't get hotter and there'd be relatively little additional wear because of the extended cool down period. There was of course no question that while the bulb was operating the fan also had to run.
