What is bulb material?
The bulb itself is made of glass and contains a mixture of gases, usually argon and nitrogen, which increase the life of the filament. Air is pumped out of the bulb and replaced with the gases. A standardized base holds the entire assembly in place.
What is an appliance bulb?
The difference between regular and appliance bulbs is that appliance bulbs are designed to withstand the extreme temperatures and conditions found in appliances. They have a stronger filament capable of withstanding vibrations and tend to be shatterproof too.

What metals are light bulbs made?
Tungsten metal is used to make the filament of an electric bulb.
Which material is best for light bulb design?
Tungsten is used in nearly all incandescent light bulbs because it is an ideal filament material.
How does a lightbulb work?
The incandescent light bulb turns electricity into light by sending the electric current through a thin wire called a filament. Electrical filaments are made up mostly of tungsten metal. The resistance of the filament heats the bulb. Eventually the filament gets so hot that it glows, producing light.
What company makes light bulbs?

Many of the products that we supply are made by GE: these include compact fluorescents, halogen reflector lamps, fluorescent tubes, discharge lamps and many other items.
What is the difference between an appliance bulb and a regular bulb?
The difference between a regular bulb and an appliance bulb is that the bulb is specially designed to withstand high and low temperatures. It also has a rugged filament that resists vibration, making it ideal for microwaves, refrigerators, and ovens.
What are A19 LED bulbs?
The A19 LED bulb delivers up to 1,600 lumens of 2700K, 3000K, 4000K and 5000K light while consuming up to 88% less energy than the incandescent bulbs they replace. The A19 is instant-on, compatible with most standard incandescent dimmers, and is ENERGY STAR® certified.
Is A21 a standard bulb?
A standard, household bulb is an A19 which is 2.375 inches in diameter, while A21 is 2.625 inches so it will depend on the space available in your light. Hope that helps!
