Hi-trac track and lighting structure is a heavy-duty infrastructure for suspending spotlights, downlights, wallwashers and pendant luminaires. The Hi-trac profiles with their wide spans of up to 4m are particularly recommended in rooms with just a few available suspension points. Two variants of the Hi-trac profile are available: Either with empty upper profile for further cable routing or with indirect distribution luminaires to illuminate the ceilings. On the lower side of the Hi-trac profile, the integrated track provides a flexible and sustainable infrastructure. Spotlights, downlights, wallwashers and even pendant luminaires can be fitted there and can also be moved or replaced with ease. Luminaires from other manufacturers can also be used in Hi-trac. We provide suitable adapters as OEM components. Wire suspensions and pendant tubes offer an elegant solution for suspending Hi-trac and light structures. The extensive range of accessories allows a variety of arrangements and makes the track a universal infrastructure. In addition to 3-circuit and DALI mode, the track is also suitable as a power supply for wireless controls such as Casambi Bluetooth and Zigbee. This makes Hi-trac track and light structures a very versatile infrastructure for lighting in museums, shops and offices.
