The photograph shows the full effect of the first phase of the Lumisphere X24 festoon lighting system installed on the Brompton Road frontage of the famous Harrods building which highlight the exceptionally fine architectural features which being clad in naturally coloured terracotta is seen to softly glow in the backlight from the spheres.The Lumisphere festoon cable has been especially produced colour coded to match the terracotta making iit unnoticeable against the background both in daylight and at night.Similar effects are obtained on the sides and rear of the building which feature a total of approximately 12,500 Lumisphere X24 light units iincorporating 8.5w lamps and clear polycarbonate spheres that are fed from Lumisphere WP24 transformers discretely positioned on the building.

Previous to the Lumisphere installation the building was for many years illuminated by a mains festoon system using 25w mains voltage lamps with a total load of over 300kW which on the assumption of an average use of six hours per day would consume 680,000kWh per annum. The Lumisphere system working at 24V and each light consuming only 8.5W although giving a similar light effect as the old 25W mains lamps gives a loading of approximately 106W consuming approximately 230,000kWh per annum saving some 450.000kWh per annum. In addition to the remarkable energy savings the use of high quality long lasting materials in the construction of the Lumisphere components, together with the exceptionally long life expectancy of the xenon lamps, will give very long maintenance free periods between lamp changes compared with the old mains system. The Lumisphere system was installed by Harrods Engineering Department and was chosen as being able to meet all the requirements for the exterior lighting after extensive research and alternative product trials.
