An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the emitter and cool ...
Website. www.sunbeam.com. Sunbeam Products is an American company founded in 1897 that has produced electric home appliances under the Sunbeam name since 1910. Its products have included the Mixmaster mixer, the Sunbeam CG waffle iron, Coffeemaster (1938–1964) [ 2 ] and the fully automatic T20 toaster. The company has endured a long history ...
Bed warmer. A bed warmer or warming pan was a common household item in countries with cold winters, especially in Europe. [citation needed] It consisted of a metal container, usually fitted with a handle and shaped somewhat like a modern frying pan, with a solid or finely perforated lid. The pan would be filled with embers and placed under the ...

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
Incandescent light bulb. A 230-volt incandescent light bulb with a medium-sized E27 (Edison 27 mm) male screw base. The filament is visible as the mostly horizontal line between the vertical supply wires. A scanning electron microscope image of the tungsten filament of an incandescent light bulb. Elaborate light in Denver, Colorado.
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 ...
