New Hampshire install non-glare LED street lights

Located in Concord, New Hampshire, United States plans to install LED street lights, pedestrian protection eyes. The city choose warm LED street lights, namely 3000K warm white 4000K LED instead of cold.

The city aims to reduce the impact of light pollution, so that astronomers can observe the night sky objects, such as stars and planets in the Milky Way.

LED street lights favored because it is more energy efficient, longer life, but when the color temperature of 4000K, it will largely affect our night vision.

Although the bright lights illuminate the road, but it will interfere with the night sky. Warm LED unlikely to affect the night sky.
