  2. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    Early dimmers were directly controlled through the manual manipulation of large dimmer panels. This required all power to come through the lighting control location, which could be inconvenient, inefficient and potentially dangerous for large or high-powered systems, such as those used for stage lighting.

  3. LED stage lighting - Wikipedia

    en.wikipedia.org/wiki/LED_stage_lighting

    A front view of a Stagebar LED striplight. LED stage lighting is a stage lighting technology that uses light-emitting diodes (LEDs) as a light source. LED instruments are an alternative to traditional stage lights which use halogen lamp or high-intensity discharge lamps. Like other LED instruments, they have high light output with lower power ...

    en.wikipedia.org/wiki/Stage_lighting_instrument

    LED instruments are an alternative to traditional stage lighting instruments which use halogen lamp or high-intensity discharge lamps. Like other LED instruments, they have high light output with lower power consumption. Most LED fixtures use three or more colors (usually red, green, and blue) which can be mixed to hypothetically create any color.

    Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, [10] and 303 lm/W in March 2014. [11] Practical general lighting needs high-power LEDs, of one watt or more.
