J-Style white track fixtures constructed with 4 feet of track, die-cast aluminum, which provides superior strength and rigidity. The design is modern, with the softened edges adding to the contemporary aesthetic. The GEMINI two-head track pack features a double yoke that provides for secure lock on vertical angle position. The solid state electronic transformer provides 120V AC to 12V AC noise-free voltage reduction and operation. The porcelain socket is designed for 12V MR16 bulbs (50W max). The bulb housing is controlled with an adjustable yoke that would provide custom aiming of 330 degrees horizontal rotation and 90 degrees vertical rotation. This track fixture is dimmable when used with electronic low voltage rated dimming controls only.
