Xenon | ˈzɛnɒn, ˈziːɛnɒn | noun [mass noun]
The chemical element of atomic number 54, a member of the noble gas series. It is obtained by distillation of liquid air, and is used in some specialised electric lamps. (Symbol: Xe)
Late 19th century: from Greek, neuter of xenos ‘strange’.

A xenon arc lamp is a highly specialised type of gas discharge lamp, an electric light that produces light by passing electricity through ionised xenon gas at high pressure. It produces a bright white light that closely mimics natural sunlight, with applications in movie projectors in theatres, in searchlights, and for specialised uses in industry and research to simulate sunlight, often for product testing. Xenon headlamps in automobiles are actually metal-halide lamps, where a xenon arc is only used during start-up to correct the colour temperature.

  1. I'm thinking that light would be unpleasant in a home or office.

  2. The notion of a noble gas always fascinated me. Too polite to throw around its electrons like those other, COMMON elements. Those hussies!

  3. hmmm I am not a fan of that kind of light ,
