In outdoor areas, surface-mounted luminaires are used due to quite pragmatic considerations: the decision in favour of lighting concepts with surface-mounted LED luminaires considerably reduces the installation complexity, for example in the case of solid ceilings or on beams. Surface-mounted luminaires are ideal for use in railway stations, airports, passageways and atriums. ERCO surface-mounted luminaires for outdoor use feature the same quality of light as luminaires for indoor applications. Luminaires for outdoor areas are also characterised by corrosion-resistant aluminium housings and, with IP65 protection, are completely weatherproof.
