Hertfordshire County Council will complete the switchover of its streetlights to LEDs over the next three years at a cost of £18.5m.
The council said it has already converted more than 40,000 of the county’s streetlights to LEDs and over the next three years the remaining 70,000 will be changed.

LEDs – Light Emitting Diodes – are cheaper to run and more reliable than conventional sodium lamps, offer improved visibility and have a longer life expectancy.
Hertfordshire said it will invest around £18.5m in the project, which will reduce operating costs by around £1.9m per year.
Terry Douris, cabinet member for highways, said: ‘Upgrading our existing lights to this modern technology forms part of Hertfordshire County Council's ongoing commitment to maintain and improve roads for the benefit of all Hertfordshire residents.'
The council has already converted its A roads with almost 13,000 new lights. The remainder are on B, C and unclassified roads and footpaths that are switched on all night and in outlying settlements and on remote footways which operate for part of the night only.
The county’s network of LED lights is connected to a central management system, which detects faulty lights and cuts inspection costs.
The brightness of the lights can be controlled, so changes to light levels can be made from a central point. This allows light levels on roads to be varied without switching streetlights off, for example if more light is needed in the event of an accident.
