The NORLYS London 4020BS is a classic lantern with four clear sides and a hipped roof topped by a knob, set above a curved bracket arm. The body is cast aluminium, powder-coated in a black finish with a silver patina (listed by Norlys as BLACK/SILVER), and the panes are clear UV-stabilised polycarbonate.
What it mounts on and what is in the box
According to the manufacturer's data sheet this is a pole luminaire: the arm is fixed to terminal 3040, which sits on top of a pole. The box holds the lantern with its arm only — the terminal and the pole are ordered separately. Norlys builds its London 482 and London 483 sets from these three parts, with two or three of these lanterns on a telescopic pole 3010. Terminals take conductors up to 2 × 2.5 mm², and an EPDM gland seals the cable entry.
The lantern is 20.5 cm wide, and the arm holds it 30 cm out from the fixing point. Compare that reach with the distance between the pole and the edge of the path: with the pole right next to a walkway, the light already falls over its surface. The fitting weighs 1.85 kg net.
Which light source to choose
Inside is one E27 lampholder for an A55–A60 shaped LED lamp of up to 9 W. No bulb is supplied, so colour and brightness depend on the lamp you choose — an LED of about 800 lm gives as much light as an old 60 W bulb. The user replaces it.
The ULOR is 1 %: the solid roof stops light heading upwards, so the lantern lights the ground below and around it rather than the sky.
Durability, service and character
The IP54 rating protects against dust and splashing water, IK07 means the housing withstands an impact energy of 2 J, and the fitting works at temperatures from −20 to +45 °C. It is protection class II, so the installation needs no earth conductor. A cracked diffuser is replaced on its own with service kit 0904800051.
The hipped roof with its knob and the decorative bracket under the arm give it a classic English character, and the silver patina sets this version apart from the plain white and black finishes. It suits a garden by a house or the grounds of a hotel or restaurant.
