More than 1,300 streets in Bolton have been switched over to new LED lighting.
Work is underway to replace lighting in the town centre, Westhoughton, Tonge, Heaton, and teams have just moved into Smithills.
Rollout started in April and will continue around the borough once these areas are complete.
Around 5,750 street lights are now using the lower energy lighting and approximately 26,000 street lamps on residential streets and main roads are being replaced with lower carbon LED lanterns over the next three years.
The street lighting programme should save the council £14m over 20 years, and reduce energy use by around 50 per cent.
The lights use less energy and last for longer. An LED lighting unit can last for up to 100,000 hours compared to a standard street light which lasts for around 15,000 hours.
The council spends £2.1m on energy bills every year, and carbon dioxide emissions cost the council £100k annually.
Bolton Council’s Executive Cabinet Member for Environmental Services, Cllr Nick Peel, said: “We’re making good progress with our LED programme and we’re on target to finish in 2018.
“We have almost completed the switch over in a few of the areas we’re working in. Heaton’s almost finished and we’ve just moved into the Halliwell area in the town centre. The plan is to also start Blackrod and Horwich early next year.
“Switching over to LEDs will save money as we will see reduced energy bills, maintenance costs and carbon taxes.”
The new LEDs are also brighter and keep the streets well lit and safe for pedestrians, cyclists and drivers, reducing the chance of accidents and crime. They also improve the quality of images captured at night on CCTV.
The LED lighting is controlled by a wireless Central Management System allowing the lights to be monitored from a central point, which reduces inspection costs and make it easier to repair faults. This system also enables lighting levels to be varied accordingly.
Bolton Council also recently won an award in the Lux Awards - a flagship lighting industry competition - for the recycling programme it has put in place for switching over street lights to lower carbon LED bulbs.
The council was praised for the work it is doing with Lumicom, a not-for-profit recycling company, to recycle the existing old style sodium street lanterns. In total, around three quarters of these lanterns will be recycled back into the environment.
