The M18 cordless LED (light emitting diode) work light has over 600 times the life of conventional incandescent bulbs and runs up to 4 times as long. With a sealed aluminum head to provide impact and weather-resistance, Milwaukee provides a limited lifetime LED warranty. An integrated hook allows hands-free use while a 135 deg (degree) rotating head allows the user to easily point the light beam at the desired work area. Battery and charger sold separately.
