Large-area high bay luminaires for fluorescent lamps are a particularly economic and optically highly efficient solution for the lighting of high halls. The specular louvres with their high level of vertical light components provide better illumination of vertical surfaces and very good all-round lighting conditions.

• Very economic operation with long maintenance intervals, low lamp costs and low energy use compared to high bay reflector luminaires
• Very long maintenance intervals and especially high level of economy with HFG-operated luminaires
• Very good all-round lighting conditions with high degree of vertical light components and an improved illumination of vertical surfaces
• Very low construction height
• IP50 and IP60 variations have an internal louvre, protected by a cover panel against soiling
  

Sheet steel housing, galvanised, inside and outside pure white (similar to RAL 9010) | mounting for wire or chain upon housing at four positions | louvres are mounted without tools and are held securely with catches. Louvres can be hinged downwards from both sides. Even when hinged downwards they remain earthed for protection. IP50 variations with aluminium frame, matt anodised with cover panel of PMMA, (IP60 variation with PC cover panel), panel with frame can be hinged downwards on one side.

Luminaires wired ready for connection; with 3-pole terminal block (HFG-dimmable: 3-pole + 2-pole for brightness control), max. 2.5mm² | as standard with HFG or HFG-dimmable (1 to 10V)

Luminaires according to variation either direct beam or direct/indirect beam distribution with c. 10% ceiling illumination | IP50 and IP60 variations with direct beam distribution • Parabolic louvre, highly specular anodised

• Extruded aluminium crossblade louvre, matt anodised
• White louvre
