Track lighting is a method of task lighting wherein metal cylinder light fixtures are set in a single track of varying length containing a series of electrical conductors that provide power to any light affixed to the track. This method allows for users to move or switch light fixtures at their choosing, for optimal lighting. These tracks can be hung on lengthwise down support columns or from ceilings and walls.
One of the major advantages of track lighting is that each light is independent of the other, allowing you to spotlight various areas of the room without having to deal with the wiring that comes with conventional lighting. Many of these lights are built with dimmers so you can provide as much or little light as is appropriate. Track lighting isn’t limited to single, rigid bars, either. Newer designs feature flexible tracks that can loop around like a railroad track to light an entire room or provide lighting to specific sections if the track is bent accordingly.
