2. LED stage lighting - Wikipedia

   en.wikipedia.org/wiki/LED_stage_lighting

   As there is no Parabolic Aluminised Reflector in an LED 'PAR', they would be more accurately referred to as 'LED flood lights'. Many LED fixtures are now made using a small number of high-output diodes that allow the beam to be focused on a "hard edge", allowing full use of gobo/beam effects. LED lighting instruments used on Radiohead's 2008 tour

   High-intensity discharge lamps are a type of arc lamp. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by ...
