The XT-A line is a series of LED office luminaires that is outstanding due to a specialized development in LED lighting technology, OSA. OSA is a patented lighting grid which gives light a brilliant appearance and realises the full performance potential of the LEDs being used. The system is characterised by a high efficiency and an above average glare reduction at the lamp head. The laser panel LP consists of a plurality of special layers produced by laser technology. The highly efficient LED light that is fed in from the sides of the luminaire is emitted upwards and downwards in an optimally glare-free manner. This allows for a very slim XT-S luminaire head, which creates a very pleasant and even illumination.
