Maytag Microwave Hood Light Bulb - Typically, they're made of a tungsten filament encased in a slim and frosted-glass. In this glass encasement is not a vacuum but a gas that is either nitrogen or argon. As electrical current runs through the thin filament, it heats up the thin wire. The temperature gets extremely high, about 2, 500ºC and the thin wire glows white hot.

Incandescent bulbs aren't very effective, releasing a great deal of heat and lasting approximately a thousand hours before getting busted. These lamps release also much heat for the light they generate and this means that much of the electrical power is being converted to heat, that is a waste power, instead of light. Thermal power is worthless because the major objective of the lamp is to generate light.


In very high temperatures, a few of the tungsten atoms depart the filament and become deposited on the internal walls of the glass bulb and trigger darkening, more lowering the efficiency of the lamp, as emission is reduced by the glass bulb. The tungsten filament does not vaporize uniformly. Instead, evaporation happens on weak spots, where vaporization of tungsten happens quicker. A split happens in this region as well as the lamp gets busted.

The difference between an incandescent one and a halogen lamp is the former is better in several aspects. Both have different characteristics, although both have the same key factor, the tungsten filament. Halogen light bulbs are smaller to concentrate heat in an inferior space. Because it is infused, the glass encasing is different.
