Launceston will be the first of six Northern Tasmanian councils to roll out LED streetlights across the region.
The City of Launceston has begun replacing more than 4800 streetlights with new LED technology that is estimated to save about 3848 tonnes of greenhouse gas emissions.
The lights will be replaced on streetlights across the city and are about 82 per cent more efficient than the current lights, that are nearing the end of their specified life.
"The move towards LED globes makes sense both economically and environmentally, and there will be clear benefits to the city's residents over the life of the new globes," Mayor van Zetten said.
"Launceston has a proud history as an innovative city, and this will continue with the largest roll out of LED street lamps by a single council anywhere in the state.”
Lights will also be replaced in Meander Valley, George Town, Break O’Day, West Tamar and the Northern Midlands regions. The other five councils will replace a further 4300 globes.
The City of Launceston project will cost $2 million and is funded by the council.
