Do Incandescent Light Bulbs Need to Be Protected?
Incandescent light bulbs generate their light through heat. A filament normally made of tungsten metal is in the middle of the bulb and electrical current heats the filament to about 2500 degrees Celsius. The light emitted by the heated filament is amplified and projected by the glass dome of the bulb. Because incandescent bulbs need both electricity and heat to work effectively, they should be protected from harsh weather elements in a few simple ways. Weather Conditions Always read the instructions on a light bulb to see what its intended use is and what warnings exist for it. Since vibration and shock can frequently damage the filament, you need a bulb with a stronger filament for use in environments where vibrations exist. The garage door light is a good example since it is subjected to constant vibration of the garage door opening and closing–and needs a sturdier filament designed for that wear and tear. Outdoor lights should be angled down and have covers on them to protect them
