What is the name of the lamp that incorporates a parabolic reflector and is sealed inside a glass lens?

The lamp that incorporates a parabolic reflector and is sealed inside a glass lens is known as a sealed beam lamp. This design features a parabolic reflector that directs light, enhancing its output and efficiency. The sealed construction protects the internal components, making it durable and resistant to environmental factors. This type of lamp is commonly used in automotive applications for headlights, as it produces a focused beam of light that improves visibility on the road.

In contrast, halogen lamps, LED lamps, and incandescent lamps do not follow this design configuration. Halogen lamps use a different type of filament and bulb construction, LED lamps employ semiconductor technology, and incandescent lamps use a filament that is also not sealed in the same manner as a sealed beam lamp.
