The Small family suits a finer scale and a lower visual presence, while Large creates a stronger line with larger proportions. Compare them against the room size, ceiling height, required module types and the technical data available within each family.
Curve supports curved routes and a softer geometric expression; Belt offers a flexible line with a distinct character; Flexi is relevant where adaptable, non-linear form is central to the concept. They are not direct substitutes, so review the installation limits and available components before drawing the route.
When comparing magnetic track lighting prices, do not use the cost of one module as the project total. Track, power supplies, connectors, mounting components and the quantity and type of luminaires form the complete system price. Define the route and lighting scenes first, then prepare a coordinated component schedule.
