Track lighting Totally Explained

Everything about Track Lighting totally explained

Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors. This is as opposed to the routing of electrical wiring to individual light positions. Tracks can be mounted to ceilings or walls, lengthwise down beams, or crosswise across rafters or joists. They can also be hung with rods from especially high places like vaulted ceilings. Typical systems have line voltage (100 volts in Japan, 120 in North America, 240 elsewhere) running through a recessed track. The track may have a second "hot" conductor, so that two circuits may control lighting on the same track. This is selected by placing the tab of the connector on the fixture to one side or the other when attaching it to the track. There are three standard types of tracks used in North America, as well as elsewhere in the world. They are often termed "H", "J", and "L" track, after the names of the manufacturers that established the standards, Halo, Juno, and Lightolier. To identify a track fixture, you may use the following two rules: 1. if it has three contacts, it's probably "H" type 2. If the contact-tips are 1 inch apart, it's probably "J" type, if they're 7/8 inch apart, it's probably "L" type.
   More modern systems are available with low voltage (10, 12, or 24 volts respectively) running through track, which is in itself decorative. In this case, the fixture may clamp onto a track made of two metal strips separated with an insulating strip. Two-circuit configurations are rare in such systems.
   A variation on this is cable lighting, whereby the fixtures are simply hung or suspended from uninsulated cables which likewise 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.
   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 electrical cord and wall plug. Cultural References In Steel Magnolias in the beauty parlor Clairee makes the comment that her nephew says that all gay men have track lighting.
