Kings Cross Station switches to Ledvance to cut energy, maintenance and running costs
New High Bay DALI luminaires from Ledvance provide modern benefits in Grade-1-listed landmark.
L
edvance LED lighting solutions have been installed across platforms 1-8 at London’s historic Kings Cross Station to significantly reduce maintenance costs and energy consumption while future-proofing the building’s illumination systems. The retrofit saw numerous traditional 400W metal halide lamps replaced with Ledvance High Bay DALI 115W 4000k luminaires with IP65 protection, fitted with high quality aluminium reflectors. The Victorian building is a site of national significance and even small changes to its structure require planning authority approval. While looking the same as the old lights and providing the same amount of brightness – both essential requirements – the new Ledvance units use much less electricity and last far longer, providing a constant luminous flux across their five-year guaranteed lifespan. Thanks to their DALI-2 certification, they can also be used with any lighting-control system that may
be installed in the future at the station, another important consideration.
“The old lamps were failing frequently and changing them required specialist lift equipment which, for health and safety reasons, could only be used at certain times of the night when the concourse was empty,” said David Goddard, head of projects UK at Ledvance. “The station needed new luminaires that were far more reliable and energy efficient, but to keep in line with the original appearance of the building they had to look the same as the old lamps.”
Over 160 High Bay DALI 155W, 4000K LEDs and reflectors have been installed across eight platforms at Kings Cross, providing energy savings of up to 60% compared to conventional high bay luminaires. Ledvance High Bay solutions are an ideal replacement for luminaires with mercury vapour or metal halide lamps as they offer the flexibility of being dimmable and can switch on and off
instantly, allowing savings to be realised through daylight and occupancy-dependent operation. This is ideal for industrial applications as well as high ceiling environments. In addition to the much lower energy consumption, Ledvance High Bay LEDs need replacing less frequently leading to maintenance cost savings.

BRE, a global leader in commercial real estate services, has managed the refurbishment of the iconic Grade I Liver Building to create a ‘best in Class’ office and leisure destination. The eighth floor is home to The Bank of New York Mellon who now benefits from a significantly improved, energy efficient lit environment.
Tom Francis, Luceco project manager, said: “We worked alongside CorEnergy, part of the SureServe Group, based in Manchester, a renewables specialist in the sustainability and low-carbon sectors. Sigma was selected for this impressive office environment due to its advanced technical performance, a direct/indirect recessed luminaire for low glare applications designed to assist with LG7 compliant settings.”
Backlit LED technology and a central Tp(a) microprism optic ensured suitability for this office environment offering UGR 19 compliance and less than 3,000 cdm2 at 65°. Platinum Mini downlighters were also used to light circulation spaces alongside Sigma. A recessed luminaire offering an efficacy up to 117 Llm/cW, Platinum Mini features a unique swing tab design for quick and easy installation.
Sigma is engineered to be installed in the traditional lay in method or pulled up to the ceiling using specially designed swing tabs. The luminaire
