London 4121WH is a classic LED lantern for pole mounting, cast in aluminium and powder-coated white (RAL 9003). The LED module is built in, so no lamp is needed, and it gives a neutral white light of 4000 K. With the appropriate accessories it can also be fitted to the corner of a building as a wall light.
Mounting and wiring
The lantern is fixed to the 3040 terminal with a single M5 screw, so the pole or bracket has to be fitted with that terminal; the remaining parts are chosen to suit the installation site. The luminaire weighs 3.55 kg, or 4.15 kg packed. Its H03VV-F 2 × 0.5 lead is connected in terminals that take conductors up to 2 × 2.5 mm², and the cable entry suits round sheathed cable of ø7–10.5 mm.
The luminaire is protection class II, so it needs no protective earth. The Philips Fortimo DLM ES module runs directly on 220–240 V mains, without a separate driver. The inrush current is 3.01 A for 32.66 µs – the figure an electrician uses when sizing the circuit breaker for several lanterns on one circuit.
How much light it gives
The luminaire draws 9.5 W and delivers 757 lm (79.7 lm/W) – roughly what an old 60 W bulb gave, so it is light for a path, an entrance or part of a garden rather than a large square. 4000 K is a neutral white, and CRI 80 means plants, façades and paving keep natural colours. ULOR 0% means no light escapes into the sky; it all goes downwards, with a BUG rating of B1-U1-G0. The lantern is not dimmable.
Durability and service
IP54 protection lets the lantern stand in the rain without any cover, and IK07 impact resistance means it withstands an impact of 2 J. It operates from −20 to +45 °C, and after more than 50,000 h the LED module still gives at least 70% of its flux (L70). The source can be replaced, but only with an LED module and only by a professional service. The classic English shape, with other RAL colours available to order, lets the lantern match a garden, a park or hotel grounds.
