Track Lighting - Cable Lighting

Cable lighting is a variation where the fixtures are hung from uninsulated cables which carry low voltage. These fixtures range from the very simple, such as two hinged rods from which a halogen lamp hangs, to the very artful, such as a human silhouette whose feet touch the wires and hands hold the bulb or its socket. Two sets of cables (such as in the corner of a room where two walls meet) can be connected together with short wires that have clips (such as alligator clips or screw clamps) at either end.

Another variation is called flex track or monorail track lighting in which the fixtures are hung from a single line monorail track attached to the ceiling using stems. There are several different types of track. Some are very flexible and can be curved in any shape or form and some are more rigid and can be curved very slightly. Some patterns that can be made are "S curves" or "spirals".

It is also common to see line-voltage tracks with low-voltage fixtures. For these, each fixture requires a small transformer to operate it. For all low-voltage fixtures or systems a special dimmer (if used) is required, as standard dimmers are cheaply made and will cause flickering because of the interaction with the inductive electrical load.

Various adapters are available for combining features of track and other lighting. If the track is properly anchored, a hanging fixture may be suspended from it. The track itself can also be suspended. Rather than being hard-wired to a junction box (which requires a feeder device to be snapped into the track, either in the middle or at one end), it can also be end-fed from a standard wall outlet. Outlets can also be snapped into line-voltage track. There are "L" and "T" adapters for rigid track, as well as flexible ones for unusual angles, or to change the vertical angle where a ceiling changes slope. Adapter plates allow single fixtures to be attached directly to a junction box, by providing an extremely small section of track embedded into the plate. There are also arms which have the same feature, allowing fixtures to be mounted onto the same wall they shine onto, and having an attached power cord and wall plug.
