This invention relates to a light fixture which is adapted to accommodate either tungsten filament and gas discharge light bulbs in an adjustable carriage to permit an operator to adjust the focus of the light and to switch bulbs to illuminate a scene, such as the scene of a motion picture film, with different lighting effects. The light fixture of this invention comprises a reflector to reflect light to illuminate a scene, a socket to receive and to hold either a tungsten filament bulb or a gas discharge bulb, a power source to provide electrical power to the socket to illuminate either a gas discharge or tungsten filament bulb, a carriage holding the socket in a position where a light bulb in a socket will extend forwardly of the reflector, with the carriage being mounted on tracks to slide linearly back and forth with respect to the reflector, a drive means under the control of an operator to move the carriage through a range of linear motion, and an adjustable connector linking the drive means to the carriage to permit an operator to adjust the position of the range of motion of the carriage to accommodate different types of bulbs.
