Linear lighting refers to a specific type of lighting where long and slender light fixtures or LED strips are traditionally used to create linear continuous lighting. Nowadays, these elongated light fixtures are often combined with a variety of spotlight options serving both general and accent lighting purposes. In fact, the terms linear lighting and profile lighting can be used interchangeably, as they essentially refer to the same thing. They are configurable made-to-measure lighting solutions that rely on a profile to ensure a precise fit for a particular space or application. 

When it comes to track lighting, we refer to a particular type of linear lighting that offers the freedom to adjust lighting fixtures even after installation. Unlike fixed linear lighting systems like profile systems, track lighting provides the flexibility to reposition modules easily on the track rail. This allows for convenient reconfiguration and adaptability within the original lighting setup.
