Warrington Borough Council is spending £25 million to replace most of their streetlights with LEDs.
The council will be replacing 18,000 street lights over three years. The switch is expected to reduce light pollution, energy consumption and carbon dioxide emissions.
A combination of fluorescent PL and Mini Luma LED lanterns from Philips will replace the existing SOX lamps. The new scheme will also come with a central management system from Philips, to allow the council to control the lighting.
Thousands of street lights have already been changed in a different scheme called Invest to Save.
The street lighting in Warrington currently costs the council £1.4 million a year in energy bills and is 17% of the authority's total carbon dioxide emissions. Over 60% of the current street lighting has been in place for 25 years or longer.
The council said: "White light has been shown to make objects appear clearer and faces more recognisable, even if lighting levels are lower. This is especially important for the elderly and those with poor eyesight."
In Liverpool. the city council is switching all of it's existing street lights to LED alternatives in an attempt to brighten it's streets and reduce carbon dioxide emissions and energy costs. The £7 million project will be completed in phases over the next two years. The first phase began this month, and will see 12,000 SOX lights swapped for LEDs. The maintenance costs are expected to be reduced by £2.7 million over five years. The council currently spend £2.6 million a year on energy from their 57,000 street lights and their illuminated signs and bollards.
Mayor Joe Anderson said: "We have decided to bring LED street lighting to Liverpool to improve the lighting across the city and make our streets safer. This will help to make our city greener and a better place to live by saving over 1,400 tonnes of carbon emissions each year."
