    Neon lamps or light-emitting diodes are commonly used for low-intensity strobe applications. Neon lamps were more common before the development of solid-state electronics, but are being replaced by LEDs in most low-intensity strobe applications. Xenon flash lamps are used for medium- and high-intensity strobe applications. Sufficiently rapid or ...
