A power tool includes a housing coupled to an electrical power source, a motor contained in the housing, and a motor control circuit that controls output speed of the motor. A light nut is coupled to the housing to illuminate a work surface. A light unit control circuit controls illumination of the light, unit. A switch unit is coupled to the housing and selectively operable to control the operation of the motor control circuit and the light unit control circuit. The light unit control circuit includes a timer configured to cause the light unit to illuminate a first brightness level when the switch unit is actuated, and to remain illuminated at the first brightness level for a predetermined time period after the trigger is actuated. The predetermined time period restarts if the switch unit is not deactivated before the end of the predetermined time period.
