Tobias Grau’s XT-A series pioneers fresh, minimalist form with the most sophisticated LED lighting. The series’ patented OSA technology features gridded LEDs in an open system, providing advanced efficiency and superior glare-free lighting. Light is neutral white, shadow-free and with superb colour rendering (3500 Kelvin, CRI > 80). The ceiling fixture XT-A DIRECT is available in a variety of ceiling models. Some XT-A DIRECT models are equipped with both a light and motion sensor to automatically regulate light to ambient brightness and area occupation. XT-A DIRECT is compatible with Tobias Grau CONNECT technology, enabling group programming of multiple lights.
