The Kosnic Isar T-bar Linkable Linear LED Luminaires are designed to fit standard suspended ceiling T-bars. The luminaires attach directly to the T-bars of the suspended ceiling forming a linkable lighting system. The luminaires are available in two different lengths and wattages, supplied by separate constant voltage LED drivers. The drivers are available as standard or dimmable and should be selected according to the combined wattage of the luminaires to be linked to each driver.
