- The inconvenience of poorly lit jobsites and the hassles of extra-long extension cords are in the past with the 20V MAX* Bluetooth LED Large Area Light. Whether using it as a cordless light or charger, it helps to illuminate work areas with a maximum of 7,000 lumens. With AC/DC capability, the light runs off any DEWALT 20V MAX* battery and can also charge DEWALT slide pack batteries when plugged into AC power. Batteries are protected via a door lock option, providing security with versatility. The light features instant on/off with no warm-up, dimming as low as 500 lumens, right/left light head and is stackable with a wheel option for convenient storage
