A fellow named H. from Moncton, N.B. has light bulbs that are constantly burning out in the garage. What to do?
The filaments in regular incandescent light bulbs is relatively delicate, especially as it gets very hot. A garage ceiling often has more than it's share of vibrations with the opening and closing of the garage door, so it is in fact the vibration against that hot filament that shortens the life span of these bulbs. Check carefully at the hardware store and you will find vibration resistant light bulbs, Sylvania even calls them "Garage Light Bulbs".
I have been asked if it makes a difference in the longevity of a light bulb if it is hung vertical up, vertical down or horizontal? The engineers at Sylvania tell me no, except for those candle like chandelier light bulbs. They come in either a vertical or a horizontal model.
