Laser level

Abstract

A laser level system including a laser level, the laser level projecting at least one laser line. The system also includes a bracket on which the laser level is mounted and a battery pack. The bracket includes a battery pack receptacle into which the battery pack is removably coupled. The battery pack powers the laser level. The battery pack has a maximum initial battery pack voltage (measured without a workload) of at least 18 volts. The system also includes at least one electrical conductor which delivers power from the battery pack in the battery pack receptacle to the laser level.
