Three-level luminaire concept for clean-rooms – The unique feature of the top-of-the-range model in the CLEAN product line is a continuous smooth safety glass diffuser. Cleaning a luminaire does not get any simpler than this. The 4 mm thick toughened safety glass does not need a frame nor is it interrupted by fasteners. The innovative magnetic fasteners combine safety with functionality. Continuous, non-ageing seals are resistant to chemicals and precision-formed to ensure a high degree of protection. Special anti-static coating resistant to cleaning agents and disinfectants eliminates the attraction of dirt and dust particles. The luminaire is surface-mounted on the ceiling by 4 point fixing as standard. A mounting frame (accessory) turns the surface-mounted luminaire into a recessed luminaire. The luminaires are flush with the ceiling.
