Many operating room lights used halogen lamps [1] [2] or xenon lamps, [3] some with backup lamps that operated in case of lamp failure [4] until the advent of Light-emitting diodes as light sources since 2007 [5] which remove the problem of heat radiation and reduce energy requirements. [6]
A closeup of a 175- W mercury vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. [ 1] The arc discharge is generally confined to a small fused quartz ...
A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm . Two varieties of such lamps exist: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor ...
A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides [ 1][ 2] (compounds of metals with bromine or iodine ). It is a type of high-intensity discharge (HID) gas discharge lamp. [ 1] Developed in the 1960s, they are similar to mercury vapor lamps, [ 1 ...
In contrast to the Mustang, the Cougar was initially released solely as a two-door hardtop. Priced $284 more than the equivalent Ford Mustang, the base price of the Cougar was $2,854 ($26,801 in 2023 dollars [4]); a fully-optioned Cougar XR-7 was $4,500 ($42,258 in 2023 dollars [4]), essentially matching the base price of the Ford Thunderbird. [2]
Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors. [ 1][ 2] This is in contrast to directly routing electrical wiring to individual light positions. Tracks can either be mounted to ceilings or walls, lengthwise down beams, or across rafters or joists.
