Powered by the M12 Red Lithium battery, the Milwaukee 2632 - 20 M12 cordless LED 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.
