I'm not sure the light profile of LED streetlights are sufficiently different enough from Mercury Vapor lighting for anyone to really notice a difference - both have significant emissions in the blue spectrum, and we used MV lighting for 40 years.
- pilsetnieks 8y agoAre mercury vapor lamps actually widely used now, or for the past decades? I thought the most common lighting type before LEDs were sodium lamps which are most definitely not blue.
- Aloha 8y agoMercury Vapor was widely used from the early 50's to the mid-70's/early 80's
