Modern lighting trial proves a success for pedestrians,
motorists and residents in St Helens.
Brighter,whiter LED lighting on show in Coronation Drive, St Helens Energy efficient LED lanterns have been trialled on Merseyside by manufacturer Philips in association with St Helens Council to help shape a European street lighting strategy. The study formed part of the BLISS project (Better Lighting in Sustainable Streets) which features trials in the UK, Netherlands, Belgium and Germany.
St Helens Council’s assistant director for engineering Rory Lingham says the project aimed to consider the social and economic impacts of changes to lighting in terms of public perception, crime, accidents and regeneration. Two sites were chosen for the Merseyside trials.The first made use of roads around Coronation Drive in Haydock to assess and compare different options for residential street lighting.The second site onTithebarn Road in Billinge helped to investigate the effectiveness of LED lighting on a heavily trafficked route. Around Coronation Drive, one street used low pressure sodium (SOX) light sources, another used high pressure sodium (SON) and a third used Philips CosmoPolis ceramic discharge metal halide lamps.
In addition, Philips SpeedStar street lanterns were installed in three streets, each with different colour temperatures. “The new lighting is of a much higher standard,” Mr Lingham says. “It enables people to recognise colours and see objects much more clearly than the previous lighting.” Site two was a 1km stretch ofTithebarn Road, linking two areas of St Helens.The road was originally lit by 23 columns, each 8m high, using a mixture of low and high pressure sodium light sources.These were replaced with 20 columns of 10m height, featuring Philips SpeedStar LED lanterns.
Greater light output of the new lanterns enabled fewer, taller columns to maintain the required light levels and distribution. In addition, controls were introduced to dim the lighting to 50% between midnight and 6am.
As a result of these changes, energy consumption for this stretch of road has reduced by 21%.The Council should also benefit from reduced maintenance costs due to use of longer life LED light sources.
