The extremely robust and powerful Multi Battery LED work light with 40 W output is compatible with 38 different 18V batteries (various Ah classes) from five power tool manufacturers: Bosch Professional, Makita, Dewalt, Milwaukee, and Metabo CAS, thanks to the brennenstuhl Multi Battery 18V system. No matter which battery system is already in use, the interface technology allows for maximum flexibility and provides the option to switch to the battery system of your choice. With just one hand movement, the appropriate adapter (all included) can be inserted into the interface. The impact-resistant work light, featuring impressive brightness thanks to the built-in COB LEDs, also includes a battery status indicator for the remaining energy of the installed battery (the batteries need to be charged externally) and a protection system for power tool batteries.
