A natural lightbeam in the Majlis al-Jinn (lit.'Meeting place of the jinn') cave in OmanLight beams were used to symbolize the missing towers of the World Trade Center as part of the Tribute in Light.
A light beam or beam of light is a directional projection of light energy radiating from a light source. Sunlight forms a light beam (a sunbeam) when filtered through media such as clouds, foliage, or windows. To artificially produce a light beam, a lamp and a parabolic reflector is used in many lighting devices such as spotlights, car headlights, PAR Cans, and LED housings. Light from certain types of laser has the smallest possible beam divergence.
