New streetlights in the Far North are expected to cut the council's annual lighting maintenance bill by as much as 40 per cent over the next two years.
The Far North District Council is replacing sodium and mercury vapour lighting systems with energy-efficient LED lamps and long-life bulbs.
Infrastructure and assets general manager David Penny said the energy-efficient lamps and long-life bulbs would reduce power and maintenance costs, with the savings more than making up for the cost of the upgrade.
As well as savings of more than $30,000 a year, the LED systems gave more intense white light.
The council had prioritised streetlights in outlying areas for new lamps and bulbs because they were more expensive to maintain, due to the long distances repair crews had to travel.
