Street lighting in London’s Downing Street has been upgraded to LED to deliver improved quality and uniformity of lighting with energy savings of at least 45% and significantly reduced life-cycle costs.
The project involved upgrading the existing heritage DW Windsor ‘Windsor’ lanterns to LED and smart light, wirelessly controlled, drivers.
Supporting the City of Westminster’s long term strategy to optimise street lighting whilst reducing energy consumption and carbon footprint within the City, DW Windsor proposed a solution that involved replacing the existing HID gear trays with retrofit LED light engines.
The new 3000K LED light engines have replaced 70W (2800K) HID, effectively maintaining the light levels while using approximately half the energy, with the potential for an additional 20% energy savings from the use of an adaptive lighting approach, controlled through the CMS. Energy consumption is reduced from 7500KWH to 4900KWH and carbon emissions have been reduced substantially from 3934kg to 2570kg.
