Lamp assembly

A lamp assembly comprises a reflector body having a rear opening for receiving a replaceable light bulb. The reflector body is adjustably mounted on a support by an adjustment mechanism comprising a plurality of ball-and-socket joints. The socket of each joint is defined by a pair of arms having mutually co-operating socket parts. The arms of said pair are pivotally secured together for relative movement between a closed position in which the respective ball is held in the socket defined by the socket parts of the pair of arms, and an open position in which the respective ball of the joint can be engaged with/disengaged from the respective socket. A latch mechanism is provided for releasably retaining the pair of arms in said relatively closed position.
