Name: Norlys KOSTER 1173AL Twin-Head Park Lantern LED 37W 3654lm 3000K, Aluminium RAL 9006, IP65 IK10
Brand: NORLYS

Two heads on one pole KOSTER 1173AL is a post-top luminaire with two heads: two arms run out to opposite sides from a central collar, each ending in a domed shade. The span is 82.5 cm, at 24.5 cm wide and 22.5 cm high. Thanks to that symmetry one pole lights both sides of a path or a drive rather than throwing light one way. Colour: aluminium RAL 9006 The finish is powder-coated cast aluminium alloy in aluminium (RAL 9006) — a pale, silvery-grey metallic, noticeably lighter than graphite. Norlys makes the same model as 1173GR in graphite, so the two-letter code suffix matters when ordering. The coating carries a 25-year anti-corrosion warranty — not a warranty on the fitting, but a statement about how long the paint lasts. 3654 lumens from the fitting, 5200 from the source The manufacturer publishes both figures separately and the gap is large here: the LED module emits 5200 lm, while 3654 lm leaves the fitting through the lenses and shades. Luminaire efficacy is 98.8 lm/W at 37 W input (the module itself draws 32 W — the driver takes the rest). Colour 3000 K, CRI 70 — the usual figure for road and park lighting, where visibility matters more than colour fidelity. Ledil VSM optics and BUG classification The fitting uses a Ledil VSM lens (IESNA type V) — a rotationally symmetric distribution, so light spreads evenly around the pole. The BUG rating B2-U2-G1 describes how much light misses its target: U2 means moderate uplight (relevant where light-pollution rules apply) and G1 low glare. Photobiological risk: RG0 or RG1 — no risk to negligible. DALI2 and NightDim control The fitting supports DALI2 and the NightDim function — an automatic reduction in output during the small hours without an external controller. On a footpath or a car park that is a real energy saving in the hours when full brightness is not needed. Inrush current is 30 A for 295 µs — a figure to allow for when sizing protection with a dozen fittings on one circuit. Power factor PF > 0.98. Pole mounting This is a post-top fitting: it slides onto a ø 50 mm spigot to a depth of 80 mm. Supplied with it is a 3.7 m H05VV-F 5G1 cable for connection inside the pole, in a suitably chosen installation box. Net weight 6.40 kg, gross 8.40 kg. Durability IP65 (dust-tight and jet-proof) and IK10 impact resistance — the top of the scale, equivalent to a 20 J blow. These are public-realm figures. The shade is clear, textured, UV-stabilised polycarbonate, so it does not yellow or go brittle the way ordinary plastic would. Electrical surge withstand: 6/10 kV. Operating range: −20…+45 °C. Declared life: 100,000 hours, about 91 years at 3 hours a day; the driver's life is also 100,000 h.
