Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors. This is in contrast to directly routing electrical wiring to individual light positions. Tracks can either 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.

E-Top HK Track lighting is usually combined with directional lamps with reflectors, such as spotlights. These lamps can run under either mains voltage or a lower (often 12V) voltage.
It is common to see line-voltage tracks with low-voltage fixtures. For these, each fixture requires a small built-in transformer to operate it. Alternatively, more modern systems are available with low voltage (10, 12, or 24 volts) running through the 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.
For all low-voltage fixtures or systems a special dimmer (if used) is required, as standard dimmers cause flickering because of the interaction with the transformers' load characteristics: magnetic transformers are inductive, while electronic ones are capacitive. The dimmers control the mains input to the transformers.
