Description
Fixed optic, two compartment recessed luminaire for high efficiency, warm white LED lamps. Passive heat dissipation system. Lamp body with die-cast aluminium radiant surface, version with perimeter surface frame. Metallised, thermoplastic, high definition optics, integrated in a rear position in the anti-glare screens. Glass covers for LED lamps. The structure of the optical system produces light emission with controlled luminance (UGR < 19). Supplied with DALI dimmable power supply unit connected to the luminaire.

Installation

Description

recessed with steel wire springs for false ceilings from 1 to 25 mm thick - preparation hole 75 x 145. Installation permitted in either a horizontal or vertical position.;
Mounting Wall recessed, Ceiling recessed
Wiring Quick-fit power supply connection to terminal block. Digital electronic cabling that allows dimming to be performed with DALI protocol or a pushbutton switch (DIM SWITCH).

Notes

The product with its white finish (01) includes optic rings for limiting luminance; a feature that renders a performance of UGR < 19 and determines slight variations in the opening of the optics (52°) and yield (0.74).
