ABSTRACT:
A light leveling device includes a stationary light instrument received in a housing, and a rotatable light instrument rotatably attached to the housing, to allow the rotatable light instrument to be rotated and adjusted relative to the housing and the stationary light instrument. A carrier is rotatably secured to the housing to support the rotatable light instrument, and a motor may be coupled to the carrier to rotate and adjust the carrier and the rotatable light instrument relative to the housing automatically. A remote control device may further be used to remotely control the motor.
