Light colour warm white, correlated colour temperature (CCT) 3000 K, general colour rendering index (CRI) Ra > 80. Mean rated service life L80(tq 25 °C) = 100,000 h, mean rated service life L90(tq 25 °C) = 50,000 h. The light source is replaceable according to the ecodesign requirements (VO (EU) 2019/2020).
Luminaire body of sheet steel, powder-coated white (RAL 9016). Screening cubes silver-grey, with fine surface structure (RAL 7001). The screening cubes can be realised in further RAL colours on request. The colour of the screening cubes has no significant impact on the luminaire’s photometric properties. Safety class (EN 61140): II, protection rating (DIN EN 60529): IP20, impact resistance level in accordance with IEC 62262: IK03, testing temperature of wire glow test in accordance with IEC 60695-2-11: 650 °C. Weight: 4,5 kg.
Polarity-protected rapid connection with mains through-wiring up to Ø 2.5 mm². Connection of the ballast unit to the luminaire (Plug ‘N Play). The luminaire’s packaging concept facilitates separate removal of the control gear unit for pre-assembly, leaving the remaining luminaire components protected until final assembly.
With external operating device, switchable. The control gear unit is replaceable in accordance with the ecodesign requirements (VO (EU) 2019/2020). Control gear unit is open-circuit proof and protected against faulty connection, short circuit, overload and overtemperature. Output ripple of the control gear unit ≤ 4 % for effective control of the LED system and for flicker-free light. The luminaire complies with the 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 harmonised appearance. Project-specific versions with varying luminaire characteristics are possible on request.
