Definition of Metal Halide

Origins

• Though the first metal-halide lamps came about in the early 1910s, they weren't sold commercially until the 1960s.
  
  

Benefits

• Metal-halide lighting is usually cost effective and can be an environmentally friendly alternative light source. Since they are so efficient, metal-halide lamps require less energy to run and they tend to last a long time.
  
  

In Aquariums

• Metal-halide bulbs make an ideal light source for aquariums with living coral, which needs a high-intensity light source in order to flourish.
  
  

In Projectors

• Many projectors come equipped with metal-halide bulbs because they produce a brighter image that lasts longer than other types of bulbs commonly used in projectors.
  
  

For Plants

• Metal-halide lamps are widely regarded as a great lighting source for indoor gardens. They produce light close enough to sunlight that indoor plants can grow without getting any actual sun.
