Which type of lighting involves adjustable spotlights on a track?

Track lighting is designed with adjustable spotlights mounted on a continuous track, allowing for flexibility in directing light exactly where it is needed. This lighting system is particularly beneficial in residential and commercial spaces as it provides the ability to highlight specific areas or objects, such as artwork or architectural features, by simply adjusting the spotlights along the track.

The versatility of track lighting makes it popular for showcasing items and providing ambient lighting in various environments. Unlike flood lighting, which typically provides wide-reaching illumination without the ability to focus light, track lighting allows for targeted application of light. Troffer lighting is generally used in modular ceilings and provides consistent illumination over larger areas, and indirect lighting directs light to surfaces, which then reflects it into the space, rather than focusing light on specific points.

Therefore, track lighting stands out as the option that directly involves adjustable spotlights on a track, making it the correct choice for this question.
