Norlys Kisa 5187GR Graphite RAL 7016 LED Bollard Light 27 W 4000 K DALI2 85 cm

Kisa 5187GR is a bollard light shaped as a cylinder 12 cm in diameter and 85 cm tall, in cast aluminium powder-coated graphite (RAL 7016). Two opposite sides carry tall oval windows of satin PMMA, through which the light leaves in both directions.

How much light, and what kind

Six Philips Fortimo LED modules draw 27 W together. The modules produce 4126 lm and 2637 lm leave the fitting, which is a lot for a bollard and enough for a wider path, an entrance drive or a forecourt by a building. The light is diffused and spreads sideways: half of the flux goes above the level of the fitting (ULOR 50%), so the bollard also lights the shrubs and walls around it, not just the ground. 4000 K is neutral white, and CRI 80 keeps colours natural.

Control and service

The fitting has a DALI outdoor driver with DALI2 control and a NightDim function; it leaves the factory programmed to maximum current, i.e. full output. Dimming needs DALI2 control or a NightDim schedule, which Norlys programmes to order. The LED modules and driver are replaced by a professional service, and the maker gives L80B20 over 72,000 h and L90B10 over 64,000 h, and 100,000 h for the driver. Surge resistance of 6/10 kV matters on long supply runs across a garden.

Mounting and connection

The bollard is fixed with three bolts through ø9 mm holes spaced at 120° on a ø65 mm circle. The fixing parts are ordered separately: a concrete-in anchor (205), a ground anchor (206), a concrete foundation adapter (206S) or mounting adapters (3080, 3086). The terminals take conductors up to 5 × 4 mm², looping on to the next fitting at up to 5 × 2.5 mm², with round cable of 8–12.5 mm diameter; five cores carry the supply together with the DALI control line. It is protection class I and needs an earth conductor. It weighs 5.9 kg.

Build

IP55 lets the bollard stand in open ground in rain and dust, and impact resistance IK08 protects it beside paths and car parks. The smooth graphite cylinder without ornament is a modern form; the maker intends it for gardens, private grounds and public areas, including hotels and restaurants.
