Nova Scotia continues switching traffic lights to energy-saving LED

HALIFAX, NS-The Nova Scotia government and six municipalities are teaming up on a project to convert older traffic lights from incandescent to light-emitting diode (LED) bulbs. The project is expected to save the municipalities a combined total of up to $113,000 per year in energy costs and reduce greenhouse gas emissions by as much as 2,300 metric tonnes per year. About 4,700 incandescent lights at 118 intersections will be replaced this year with LEDs. These units reduce energy costs by 90% and can last as long as ten years, compared to only two years for incandescent bulbs. The Department of Energy's total investment of $173,658 will be divided among the six municipalities as follows: New Glasgow, $5,713; Digby, $1,255; Yarmouth, $4,178; Halifax Regional Municipality, $150,018; Annapolis Royal, $1,226, and; Bridgewater, $11,268. The traffic signal conversion project is part of the department's Smart Energy Choices program. A similar program last year switched nearly 2,600 lights to LED in six communities. Throughout Nova Scotia, traffic lights owned by the Department of Transportation and Public Works have already been converted.
