STREET lights in Gloucestershire are being replaced with greener technology to reduce energy costs.
As part of a new project, Gloucestershire County Council are replacing 1,000 street lights coming to the end of their life across Gloucester and Cheltenham.
The operation will allow engineers to introduce the latest light-emitting diode (LED) technology, rather than replacing the existing light.
It follows work already carried out to convert lighting in traffic signals and bollards. Some areas have also seen lights partially dimmed at night.
By the end of this year, it is hoped 3,000 of the council's 59,000 street lights will run using LED technology, saving 300 tonnes of carbon a year in energy emissions.
LEDs are more environmentally friendly and cheaper to run.
They use less energy and require routine maintenance every three years rather than the 'discharge' lamps which are maintained annually.
Councillor Vernon Smith, cabinet member for highways and flood, said: "We are making multiple savings here by installing new LED technology on aging street lights at the time when essential replacement is needed.
"LED street lights can use up to 70 per cent less energy than conventional sodium lights and cost less to maintain.
"They also reduce light pollution and give off a whiter light, making it easier to see, so people feel safer."
The new lights will be linked up to the council's Central Management System, which monitors new street lights.
It is also expected to make it easier to see CCTV images.
The council trialled 65 LED street lights in Dursley in 2011. It plans to extend the project, introducing LED technology to an extra 1,500 street lights in six areas of Cheltenham and Gloucester.
