LED street light conversion
We’ve replaced most of the traditional high-pressure sodium (HPS) street lights with LEDs throughout the province. HPS street lights produce a yellow or orange light and only last up to 5 years. In comparison, LED street lights produce a more direct and visually appealing white light and can last up to 20 years. LED fixtures consume nearly 60% less energy than HPS technology.
- About 97% of all streetlights from Emerson to Churchill are now LED – that’s approximately 130,000 lights.
- Almost all the 75,000 street lights in Winnipeg have been converted to LED, except for a few specialty street lights in areas like Portage and Main, Waterfront Drive, Provencher Avenue, and Graham Avenue.
- Work also continues to convert the lighting at some provincial highway intersections.
- reduced energy use;
- last for up to 20 years;
- less maintenance;
- produces a more direct white light;
- better illuminates the street for pedestrians and vehicles;
- completely recyclable;
- reduced light spillage.
The switch to LED street lights is expected to save 35 GWh in electricity savings and 6 MW in winter peak demand savings. The power we will save by switching to LEDs can be exported to provinces and states that don’t use green power. These exported savings are about 27,000 tonnes of indirect greenhouse gas emissions, which is equivalent to the energy consumed by 2,200 average homes in Manitoba in one year.
Any type of light can strobe, but LEDs require so little power to turn on they strobe really quickly. They also over-perform in cold weather. The reason they blink is because there’s not quite enough power to turn them on fully, but enough power to turn them on briefly.
The cause of strobing is usually poor grounding, bad wiring or connections which cause voltage leaking, which we can fix. Other causes are faulty LED chips or drivers, which can be replaced.
