LUX EXCLUSIVE: THE largest hanging light in the world has been unveiled at a central London bank.
The 12m-wide circular pendant – acknowledged by the Guinness Book of Records as a world record – boasts 15,000 LEDs delivering 390,000 lumens for a total energy consumption of 2.7 kW. It weighs almost two metric tons and is finished in Analok 543 bronze to match the bank’s wall panels. A second, 5.8metre ring featuring 3,000 LEDs completes the statement lighting installation.
The light fittings were built by Spectral at its parent company Ridi’s factory in Jungingen, Germany. The concept is by architects Sheppard Robson and a detailed design was produced by Troup Bywaters + Anders.
As Overbury, the contractors, could only use a 4m hydraulic lift to access the space, the Spectral team constructed thirty 1.2m-long individual sections which were bolted together on site.
The mammoth fittings are suspended off the existing beams, each one diamond drilled to take a special heavy-duty fixing.
As the fittings were plugged together on a scaffolding tower 11 metres above the floor, the PCBs, LEDs and power supplies were all pre-installed with plugs and sockets.
The suspension system – comprising an eyelet with a special ‘shock bolt’ loaded with pink powder which would explode if the loading on one cleat was too great – was developed in partnership with German company ERS.
