Product code Q428 iN90 Q428: Minimal initial moduleDown Office / Working UGR < 19L 2397 Technical description: Initial profile in extruded aluminium - Minimal (frameless) version for flush with ceiling mounting; micro-prismatic screen for controlled luminance emission UGR < 19 - 3000 cd/m2 (working lighting); screen set up for connecting several lengths by overlapping. Installation: Installation can be recessed, surface, ceiling and pendant-mounted using suitable accessories to be ordered separately. The initial modules can be used individually for various applications if completed with accessory caps and the required LED module. Colour: White (01)* | Aluminium (12)* Weight (Kg): 5.9 Mounting: ceiling recessed|wall surface|ceiling surface|ceiling pendant Wiring: Set up to house the LED modules required by the system. Notes: Take care with the system configuration. To make continuous lines of lighting, use the intermediate modules. To complete a continuous line correctly there must always be an initial module at the start or end of the composition.
