This is not my experience. In The Netherlands green LED's are applied more and more often for streetlighting in rural areas and surveillance of building construction sites (light pole + camera).
First time encounter takes some getting used to, because we are so familiar with orange Sodium hue. But I find they make the night landscape more peaceful and serene looking.
Green spectrum is perfect for the human eye. You see more detail and sharper focus, seems to me (compared to orange). Apparently its also good for nature. Not only to insects, but also birds not getting distracted.
- jacobolus 7y agoOrange is a lot better if you want to keep your night vision and be able to see into the shadows (or e.g. look at the stars with your unassisted eyes).
- brandmeyer 7y agoContrary to popular belief, cyan is better for night vision. Your rods are most sensitive to cyan, so you can use much dimmer cyan light than you can use red/orange light. http://stlplaces.com/night_vision_red_myth/ http://stlplaces.com/night_vision_red_myth/
- jacobolus 7y agoThe question is not what you can see best with the least energy, but what kind of glare in your peripheral vision will cause bright-adaptation. Your page there seems to be based on its author looking at the sentitivity curves for rods and cones and then speculating, but not as far as I can tell based on experimental evidence about how well the eyes stay dark-adapted. Edit: Moreover, the type of lamps appropriate for medium-bright street lighting and the type of lamps appropriate for briefly turning on to dimly see your camera gear while you fiddle with it when you are out taking night-sky photographs are quite different. Disclaimer: I am not an expert on triggers for brightness adaptation. I should try to hunt up some research papers sometime.)

- JohnJamesRambo 7y agoI agree, I work in green light a lot and it actually gets kind of addicting. It’s nice, very soothing and you can concentrate on what you are doing.
