LED street lights are very beneficial to the environment. The advantages are as follows:
1.They consume less energy than standard High Intensity Discharge (HID) lamps and last three times as long.
2.It also reduces greenhouse gas emissions and maintenance costs.
3.Generally speaking, LED lamps have little impact on light intrusion, because they emit direct lighting.
Due to its excellent quality, many cities have begun to turn from HID to LED street lamps.
However, some cities have not considered that although LED street lamps can emit light of different colors, not all colors should be used for public outdoor space. Bright blue and white light will bring some problems to residents, local wildlife and night sky visibility. For street lamps, the warmer the color/relevant color temperature (CCT), the better.
CCT will tell you the white tone and hue of a specific street lamp. It is measured in Kelvin (K), similar to Celsius. Different temperatures on the Kelvin scale represent different colors. For example, the light from 2000K-3500K looks more like orange/yellow, which is called super warm or warm white. With the increase of Kelvin temperature, the color will become more “paper white”, called natural or neutral white (3500K-5100K), and finally become blue white, called cold white (5100K-20000K). Due to the wider exposure range of blue light, cold white LED lights used outdoors at night will cause light pollution or brighten the sky. This will reduce the visibility of stars and may have a negative impact on astronomical research. If cold white LED lamps are used, they shall be shielded or aimed directly downward to prevent light pollution.
Our AST04 street lamp can be changed from 2700K to 6000K. You can choose a variety of color temperatures, and can only control urbanization. It has obvious advantages in your bidding for large government projects.
