Incandescent Bulbs

[Chuck]

The rough service bulbs are much more rugged. The longest lasting  
bulb in history is a rough service bulb with a heavy filament in a  
fire station in Livermore CA. It has been burning for over 1006 years.

To get that way they have a thicker filament.

This means more energy with more heat and less light. from what I  
understand. Plus they are clear and make for some real ugly lighting.

My guess is that it is more of a coincidence than anything else.

I agree with you that they dimming up to lower wattage (80%) makes  
them last longer. I have a lot that have been around for a long time.

Have you looked at halide bulbs. I just got a few that seem to be  
really bright and can dim. They are more efficient also. I don't know  
about how rugged they are.
