The TRACE track system permits a sequence of spots and pendant lamps. Various track lengths can be individually combined with different luminaires and spots. The tracks are either mounted directly onto the ceiling or suspended from it. The ballasts are concealed inside the tracks, which can be joined to create the required length using a connector. Besides the NICE pendant lamp and STUDIO spot, other pendant lamps from the Tobias Grau collection are also available for use with this system and can be interchangeably mounted with the appropriate adapter.
