The square low-voltage QRB version of our NEW TRIA downlight series is available in either matt white or brushed aluminium colour version. The generously chosen rotation and tilt range guarantees the individual orientation of light, whether you choose standard halogen or LED retrofit lamps. To operate the NEW TRIA downlight a suitable low-voltage transformer providing 12V alternating current is required. This luminaire is compatible with bulbs of the energy classes: D - A+
