Various types of glow starter. A glow switch starter or glowbottle starter is a type of preheat starter used with a fluorescent lamp. It is commonly filled with neon gas or argon gas and typically contains a bimetallic strip and a stationary electrode. The operating principle is simple, when current is applied, the gas inside ionizes and heats ...
1875 Henry Woodward patents an electric light bulb. 1876 Pavel Yablochkov invents the Yablochkov candle , the first practical carbon arc lamp, for public street lighting in Paris. 1879 (About Christmas time) Col. R. E. Crompton illuminated his home in Porchester Gardens , using a primary battery of Grove Cells, then a generator which was better.
An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on.
A space heater sold on Amazon is being recalled due to the potential to cause an "electric shock," resulting in a fire hazard, the U.S. Consumer Product Safety Commission (CPSC) announced Thursday ...
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
The GU24 fitting is intended to maintain the energy efficiency of the light by preventing an occupant from using an incandescent bulb instead of a CFL. Adapters to use incandescent bulbs in a GU24 fitting are illegal in the State of California as they would be a fire hazard in fixtures designed for the lower heat output of a CFL bulb. [2]
To reduce unintentional ultraviolet (UV) exposure, and to contain hot bulb fragments in the event of explosive bulb failure, general-purpose lamps usually have a UV-absorbing glass filter over or around the bulb. Alternatively, lamp bulbs may be doped or coated to filter out the UV radiation. With adequate filtering, a halogen lamp exposes ...
A petroleum-based fire starter for grills, camp fires, stoves or ovens A variety of firelighters on sale in a German supermarket. A firelighter is a small solid fuel tablet for fire making. Firelighters marketed as consumer products may be used to start a wood or coal fire in a fireplace, wood-burning stove, or solid-fuel portable stove. [1]
