What is another word for incandescent lamp?
Pronunciation: [ˌɪnkɐndˈɛsənt lˈamp] (IPA) 
An incandescent lamp is commonly referred to as a light bulb or a filament bulb. The term bulb is the most popular synonym for incandescent lamps. Other synonyms for incandescent lamps include tungsten filament bulb, halogen bulb, and Edison bulb. These bulbs all use a wire filament that is heated to incandescence by an electric current to produce light. The halogen bulbs are the most efficient, while the Edison bulbs are likely the oldest and least energy-efficient type. In recent decades, incandescent bulbs have been phased out in many countries because of their energy inefficiency, and they have been replaced by more modern and energy-efficient alternatives such as LED bulbs.
