Virtually all projectors sold for professional or consumer applications use HID lamps as a light source. The most common lamps are ultra‐high pressure mercury lamps for most applications and xenon lamps for high‐end applications. New light sources including lasers, LEDs and microwave‐powered electrodeless lamps are challenging the dominance of HID lamps. This paper highlights the advantages and limitations of projection light sources, including example applications.
