Norlys Borg 6155AL Post-Top Luminaire Aluminium LED 53 W 4000 K DALI2

Borg 6155AL is a post-top luminaire shaped as a flat, round disc 51.2 cm in diameter. The body is cast aluminium, powder-coated in the aluminium shade RAL 9006 — a light, silvery grey. Underneath, the disc is closed by a clear PMMA lens seated on a silicone gasket.

Dimensions and pole mounting

Including its mounting sleeve the luminaire is 15.4 cm tall, while the disc itself is 7.5 cm. The sleeve slides onto a 60 mm diameter pole to a depth of 95 mm. The pole and other accessories are not included: the mounting adapter (154XX0010) and the reduction (3070XX0009) are sold separately by the manufacturer.

The luminaire comes with 6 m of H05RN-F 6G1 cable, to be connected in a junction box chosen to suit the installation. It is a protection class I fitting, so the protective earth conductor must be connected, and the Norlys manual calls for installation by a licensed electrician. The luminaire weighs 4.92 kg.

How much light it gives

The Philips Fortimo LED module is built in and ships with the luminaire, so there is no bulb to buy. Drawing 53 W, it delivers 7200 lm at 4000 K — a neutral white under which paving and planting keep their natural colours. The LED module and driver may only be replaced by a service technician or a similarly qualified person.

A Ledil VSM lens spreads the light symmetrically to IESNA type V, producing an even, circular pool of light around the pole. The upward light output ratio (ULOR) is 0%, so no light is emitted above the plane of the luminaire into the sky.

Control and operating conditions

The driver supports DALI2 and NightDim, so the luminaire can be dimmed from a lighting control system or follow a programmed night profile. It leaves the factory set to the maximum permitted current; other parameters are programmed by Norlys after agreement with its sales department.

IP65 means full protection against dust and water jets, and IK08 means an impact-resistant housing — relevant for a luminaire standing in public space. The manufacturer specifies an operating range of −20 to +45 °C. The plain, minimalist form without ornament is intended for streets, parks and squares, as well as the grounds of hotels and restaurants.
