Concerns about LED street lights

The city is proceeding with installing LED street lights, as came up here on the blog recently. The question what colour to use has been discussed – the Coderre administration, which started this, wanted 4000K, which is relatively cold and blue, but wavered over colours varying from 1800K to 3000K in some cases. The problem is that studies show that daylight at night confuses the hell out of our bodies and brains, and is also no good for plants and animals. Experts are contesting the decisions being made.
