LED traffic lights help Council to reduce their carbon footprint

Most of the world’s traffic signals currently use incandescent halogen bulbs, which are in the majority being used 24 hours a day, 7 days a week and 365 days a year. In aid of saving energy some councils are looking to change the current bulbs in the traffic lights to LED’s (light emitting diodes). By changing the bulbs councils are hoping to reduce their carbon emissions by up to 300 tonnes every year which will give an annual saving of around £60,000.

Why invest in these good ways to save money?

Councils are able to get an interest free loan to help improve energy efficiency; this is called the Salix Fund. Lincolnshire County Council has already started on this project.

Tim Clark, traffic signals manager said “We started replacing the lamps in March and hope to complete the work by September”

Advantages

As well as the long-term financial savings involved in this campaign there are other advantages to making the change to LED lights now.

  • Whilst halogen bulbs only last for a few months, LED bulbs last for years. There is a considerable saving to be made in regards to the up keeping of the lights as manpower, vehicles and also the cost of the bulb are all elements that need to be considered.
  • LED’s are brighter than halogen bulbs as they fill the entire space so have equal brightness across the whole surface area.
  • LED bulbs save lots of energy and are also open to the possibility of using solar panels instead of electrical lines to save more energy in remote areas.
