Powered by the M18™ Red Lithium™ battery, the M18™ cordless LED work light has over 600X the life of conventional incandescent bulbs and runs up to 4X 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 degree rotating head allows the user to easily point the light beam at the desired work area.
