Laser lamp
A laser lamp is a light bulb that uses mirrors to direct a laser on to a phosphor that then emits a light. Laser lamps use half as much power as LED lamps. They were first developed by BMW for use as headlights in their cars.〔http://auto.howstuffworks.com/laser-powered-headlight3.htm〕 ==References==
