halogen
A gas used in bulbs to produce a very crisp white light unlike tungsten, which is soft and rosy Halogen bulbs are good for areas that require concentrated pools of light and are often used in track lighting and spotlights for shops They are smaller - and more expensive - than the average sized bulb You often need a transformer, which is either integral or attached to the fitting Check whether you can use a dimmer with the model you choose - some low energy bulbs are not compatible
halogen
Incandescent light source that uses metal halides in compact, highly efficient bulbs, tubes or reflectors; special fixtures are required for their use
halogen
Any of a group of five chemically-related, nonmetallic elements that includes bromine, fluorine, chlorine, iodine, and astatine Can combine with metals to form salts or substitute for hydrogen in many organic compounds The resultant halogenated compound is generally less flammable but more toxic
halogen
{i} any of a number of electronegative elements which form a salt when united with metals (Chemistry)
halogen

halogen
Halogen lights have a very yellow light not appropriate for aquarium use Do not confuse these with metal halide lights
halogen
A type of incandescent lamp with higher energy-efficiency that standard ones
halogen
Any of five nonmetallic elements fluorine, chlorine, bromine, iodine, and astatine with similar chemical properties. They occur in the second rightmost column of the periodic table as usually arranged. All are highly reactive oxidizing agents (see oxidation-reduction) with valence 1 (for fluorine, the only valence). They combine readily with most metals and nonmetals to form a variety of compounds and never occur uncombined in nature. A radioactive element, astatine occurs naturally in minute amounts as an intermediate decay product; it has no stable nonradioactive isotopes. Halogen salts formed with metal atoms (halides) are very stable; sodium chloride is the most familiar. The halogen lamp takes its name from the halogens included in the gas within its tungsten-filament bulb, added to prolong filament life and increase brightness

halogen
