Koster 1912CS Rust-Colored LED Outdoor Wall Sconce by NORLYS

NORLYS Koster 1912CS is an outdoor LED wall light with a straight projecting arm and a rounded hood that opens downwards. CS identifies the finish described by the manufacturer as corten steel. The body is actually powder-coated cast aluminium, not bare steel. Treat the rust-coloured designation as a finish choice when matching the light to architectural details.

Allow for the projecting arm

The fitting measures 24 cm high and projects 44 cm from the wall. Its hood is 24.5 cm in diameter, while the circular wall base measures 12 cm. Compare that projection with the opening path of doors, shutters and other moving elements before choosing the mounting position. This is not a flush-fitting wall light.

The round base, straight arm and broad hood give Koster a classic profile with an industrial reference. Its rust-coloured finish can be coordinated with brickwork or similarly coloured metal details. The finish name does not mean the body is made of weathering steel or that it develops a natural steel patina.

Warm light directed below the fitting

The integrated LED module uses 17.5 W and provides a warm-white colour temperature of 3000 K. The luminaire output is 1568 lm, distinct from the light source's 1950 lm rating. Its symmetrical distribution is directed downwards. When planning an entrance, terrace wall or area beside a garage, consider the surface below the fitting rather than expecting an upward beam.

This version is not dimmable. There is no E27 bulb to select: the LED module forms part of the fitting. The manufacturer allows replacement of the LED light source by professional service only, so maintenance is not the same as unscrewing a household bulb.

Installation and the light-source cover

Wall mounting uses three 7 mm fixing holes, spaced according to the supplied connection box. The electrical supply is 220–240 V, and Class I construction requires a protective earth connection. Follow the installation instructions for the cable entry and gasket to maintain the IP54 protection rating. The transparent, textured polycarbonate cover over the light source is UV-stabilised.
