LED track light

◆ Excellent thermal management, Ultra-High-Power LED with safe junction temperature
◆ Constant current driver mode for steady power supply.
◆ Energy saving, more efficient than Incandescent and Halogen lamps.
◆ Ideal for shops and showrooms

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 is probably "H" type 2. If the contact-tips are 1 inch apart, it is probably "J" type, if they are 7/8 inch apart, it is 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. The track is powered by a transformer which converts the high voltage into low voltage. There are magnetic and electronic transformers.
