The Norlys London Big 4132BC is a triple garden lantern on a straight arm, measuring 43 × 30.5 × 65 cm, in a copper patina finish. Three lantern shades sit on a common head made for a pole — this is a system component, not a standalone fitting ready to screw to a wall.
Light aimed downward
The most interesting figure on this lantern is a ULOR of 0% and a BUG classification of B1-U1-G0. ULOR states what share of the flux escapes upward — here, none. For a lantern of classical form that is unusual: most such fittings emit all round and light mainly the sky. The manufacturer marks this model as dark-sky friendly, which counts in practice where local light-pollution rules apply — and simply towards the neighbours.
Three modules, one pole
Three LED modules of 9.5 W each give a combined 2271 lm from the fitting at 3000 K. The two quoted figures are worth separating: the sources themselves generate 3300 lm, but 2271 lm leaves the optics and shades — and it is that second number that describes the light actually reaching the ground. Luminaire efficacy is 79.7 lm/W. The light source is integrated and not replaceable.
Durability and installation
The body is painted cast aluminium — the material chosen for fittings that stand outdoors for years. IP54 protects against dust and splashing, and the IK07 impact rating covers blows of 2 J, which for a lantern beside a path or driveway is not theoretical. The operating range is −20 to +45 °C. The head fixes through 3 holes of ø10.5 mm spaced every 120° on a ø240 mm circle; the terminals accept conductors up to 4 × 2.5 mm² and allow loop-through wiring, so further lanterns are chained.
