Almost 10,000 street lights in Bolton have been switched over to new LED lighting.
Work is currently underway across the borough and around 1,700 streets are now using the lower energy lighting.
Bolton Council’s executive cabinet member for environmental services, Cllr Nick Peel, said: “It’s a huge achievement to reach this milestone. We’re more than a third of the way through the programme and some areas such as Westhoughon and Halliwell are almost complete.
“Switching over to LEDs will save money as we will see reduced energy bills, maintenance costs and carbon taxes.”
Approximately 26,000 street lamps on residential streets and main roads are being replaced with lower carbon LED lanterns, with work due to finish in 2018.
The street lighting programme should save the council £14 million over 20 years, and reduce energy use by around 50%.
