Aerolux Light Corporation was a manufacturer of artful gas-discharge light bulbs from the 1930s through the 1970s. [1] Aerolux made these bulbs in a factory in New York City . US Patents dating back to the 1930s describe the design and construction of these bulbs.
The small size of halogen lamps permits their use in compact optical systems for projectors and illumination. The small glass envelope may be enclosed in a much larger outer glass bulb, which has a lower temperature, protects the inner bulb from contamination, and makes the bulb mechanically more similar to a conventional lamp.

Incandescent, halogen and HMI light sources use this design. Medium bi-post (G22) is used with film & stage lighting fixtures between 250 and 1000 watts. Mini bi-post (G4-G6) Common types: G4 – 4 mm (0.15748 in) pin spacing GU4 & GZ4 – same as G4 and only denote what lamp mount clip is needed to hold the actual light bulb in place
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting . Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
The pendant light at Fire Station #6 in which the bulb is installed. The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket ...
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...
They take the SX-70 film, a format with a ~3.1 × 3.1 in 2 (77 × 77 mm) square image area and a ~4.2 × 3.5 in 2 (108 × 88 mm 2) total area, [1] and a sensitivity around ISO 160. They come with a built-in 6-volt zinc chloride "PolaPulse" battery pack, [ 2 ] replaced with a lithium-ion pack in Polaroid B.V. remakes.
Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens ) to protect the light source and reflector, a battery ...
