The project was undertaken at the request of The Royal Household, in an effort to reduce energy consumption and maintenance costs.
The centre room chandelier was nominated and all 32 25 watt tungsten lamps were removed, and a low voltage system controlling 2.8 watt light emitting diode lamps (Queens Chandelier STL610-48-XIW-024M) were installed, initiating an energy saving in excess of 80%. The next re-lamping will not be needed to be scheduled until 2020.
