New legislation by the Province of Nova Scotia will require that all street lights be converted to LEDs within five years. Due in part to it’s smaller size, Nova Scotia will be the first province/state in North America to convert street lights to LED.
Current street lights use sodium vapour bulbs, which must be kept at a higher pressure, and a significant amount of energy is lost as heat. Light-emitting diode (LED) lights require far less energy to run, as they convert most of their energy into light.
Although initially expensive, an all LED system has been estimated it will save Nova Scotia Power ~$18 million a year in maintenance and energy consumption. The cost savings won’t be immediate though, as the Nova Scotia Government estimates the project would cost about $100 million for the materials and manpower to convert the roughly 120,000 street lights in the province.
Amherst-based LED Roadway Lighting looks poised to win the contract, but bidding for the contract is still open. A pilot program, supported by a grant from ecoNova Scotia in 2010, began converting street lights to LED in Halifax and six smaller Nova Scotia communities.
