Incandescent lamps use what to make light?

Incandescent light uses heat to make light1

Incandescent lighting uses heat (thermal radiation) to produce light. Sunlight and Candle light are generated in this way. Incandescent Light Bulbs also generate heat (thermal radiation) through a "filament". The filament heats up to produce light like a candle.

The great advantage is that this type of light quality and color is generally very consistent between most brands. Its color qualities are also very close what the Sun produces. The great disadvantage is that this type of bulb requires lots of energy which is wasted as dissipated heat (90%). Also, the intense heat causes faster degradation of the filament leading to a shorter lifespan of the bulb.

Tungsten is a hard metal that doesn't melt or degrade easily, and so it makes a good material for a filament.

Halogen lights are a type of Incandescent Light but contain Halogen gas inside the bulb to slow down degradation of the filament, allowing it to withstand more heat, and making it suitable for high intensity lights (e.g. car head lights).
