Technical Specifications

Rectangular or square shaped, anodized aluminum body, IP20 LED ceiling luminaire, characterized by:

  • 1.

    TR95% PVD matt aluminum sight blocking light distribution and glare control angled cubic louver without underlay diffusing elements.

  • 2.

    suitability for recessing in T24 600 x 600 and 625 x 625 mm grid ceilings as well as plaster & clip-in system ceilings and pendant, surface and rail track mounting with accessories to be ordered separately.

  • 3.

    providing precise light distribution control over 40,6⁰ ensures excellent glare-free (UGR <9) visual comfort and photometric performance guaranteeing average 96.9%(TM5 utilization factors table average) of generated light to be conveyed directly to working plane.

  • 4.

    eco-friendly construction enabling easy disassembly & re-cycling of components and easy replacement of lamp unit as required by ecodesign.

  • 5.

    energy efficacy level ranging between 133 to 143 lm/w combined with high UF values enabling the driving of the luminaires at low current levels which in turn provides low LED junction temperature promising luminaire efficient service life / L80B10 (tq 25°C) >50.000h. and chromatic stability / color consistency over the entire luminaire life.

  • 6.

    10 µm natural anodized aluminum body. Further color anodized and RAL colors painted finishes on request.

  • 7.

    open-circuit proof control gear unit, protected against faulty connection, short circuit, overload and over-temperature.

  • 8.

    replaceable control gear and PCB lamp unit.

  • 9.

    control gear unit output ripple <5% - PSTLM ≤1 - SVM ≤0.4 for effective control of the LED system and for flicker-free light.

  • 10.

    complying with fundamental requirements of applicable EU regulations and product safety legislation and bears the CE symbol. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires with a harmonized appearance. Project-specific versions with varying luminaire characteristics are possible on request.
