A

Valance lighting

23
Q

is an artificial light that works by incandescence, w/ an enclosed filament that when heated through the lamp base, it emits a visible light. It is the first modern electric lamp made during 19th century.

A

Incandescent lamp

24
Q

(halogen) is also called a quartz-iodine lamps, which uses a halogen gas cycle in preventing rapid depreciation of the lamp filament. It is made due to the short lifespan of a bulb, and it also emits a very high temperature.
