Does anyone know what temperature the new LED street lights are? Or better yet the actual spectrum of them?
Blue light has much greater melatonin suppression than lower frequencies of light, which can interrupt your circadian rhythm and negatively impact sleep (which has a whole set of health risks).
Blue light also kills night vision, and the LED lights are more directed, so those two things probably contribute to the perception that you can't see as well between the lights when the actual light level might even be identical to what it was with the more amber coloured light.
