A lamp that produces very short, intense flashes of light by means of an electric discharge in a gas. The ability of strobe lights to freeze the motion of rapidly moving objects by making them visible for only a fraction of a second makes them very useful in photography and in measuring vibration and other types of high-speed motion.
