NORLYS Koster 1839GR graphite LED pole-top luminaire 17.1 W 4000 K DALI2

A graphite Koster luminaire for a pole

NORLYS Koster 1839GR is a single pole-top luminaire designed for a Ø50 mm pole. Its restrained, balanced silhouette gives paths and building surroundings a clear order without competing with planting or architecture. The graphite powder-coated aluminium casting is paired with a transparent structured polycarbonate diffuser that is UV stabilised.

Even light where it matters

The integrated 17.1 W LED module delivers 2002 lm of neutral 4000 K light. Its broad, symmetrical distribution supports an even result beside a driveway, along a pedestrian route, near an entrance or through a garden. DALI2 compatibility and NightDim make this outdoor pole luminaire a considered choice for a controlled lighting scheme rather than a simple decorative fitting.

Technical essentials

• mounts on a Ø50 mm pole with an 80 mm insertion depth,
• luminaire dimensions: 45 × 24.5 × 24.5 cm,
• integrated LED: 17.1 W, 2002 lm, 4000 K and CRI 70,
• IP65 ingress protection and IK10 impact resistance,
• powder-coated aluminium with a transparent polycarbonate diffuser.

For planned exterior routes

Koster works naturally beside walkways, garden routes and access areas where reliable orientation after dark is important. Match it with a compatible pole and the intended DALI2 control design before installation. The light source is integrated, so the luminaire is supplied as a complete lighting element rather than a fitting for a replaceable bulb.
