Jan 20, 2017: The city of Montreal, after weeks of debate and dilemma, has finally decided to cancel the plan to install high-intensity LED lighting, replacing 132,000 streetlights citywide, over fears that the blue-white LED light can cause health problems and add to light pollution.
Mayor Denis Coderre announced that the city will install the less intense 3,000-Kelvin LED bulbs in residential areas, instead of the brighter 4,000-Kelvin bulbs that it was initially planning to.
He also pointed out that new technologies will allow the city to dim the lighting in certain areas, based on need and feedback of the residents.
However, in places where security is a top priority, like parking lots, underpasses, commercial and industrial zones, and large thoroughfares, 4,000-Kelvin LED bulbs will be installed and evaluated as part of a pilot project.
Montreal has already installed 1,909 4,000-Kelvin LED lights. But in residential areas, these will be replaced with 3,000-Kelvin LED lights.
It will cost the government $400 for the new light and $600 in manpower to replace each streetlight. The city intends to replace all its lights with LED lights in the next five years.
