Britains traffic lights responsible for 57,000 tonnes of CO2 emissions
news | lighting | energy efficiency
Great Britain's 420,000 traffic and pedestrial signal light bulbs are currently responsible for almost 57,000 tonnes of
carbon dioxide emissions thanks to the 100 million kWh of electricity they use each year. Currently the vast majority of the lights are of the standard
incandescent type (pictured above), but are slowly being replaced with longer lasting and more energy efficient
LED bulbs (pictured below).
The standard
incandescent bulb used in traffic signals currently uses 50 Watts of power and lasts just 12-18 months.
LED light fittings however are easier to see in daylight and poor weather conditions, use just 17 Watts of power, and last well over 5 years.
The costs for a standard red-amber-green
head is currently around £150 compared to over £600 for an equivalent LED model however LED prices are falling rapidly. Therefore, although the initial up-front costs are more for LEDs, overall costs are lower thanks to a reduction in energy used and far lower maintenance costs.
