Information Sheet LED streetlights are durable, long-lasting and cost effective and can lead to enhanced public safety while delivering environmental advantages because they use less energy while delivering enhanced visible light. After completing pilot programs and a technical analysis of current products that meet our engineering requirements, we found mainstream LED streetlights to be of utility-grade quality and on par with the reliability standards we must maintain. Q. Will residents notice a difference compared to the existing lights? A. Yes. Old residential streetlight technology such as high pressure sodium has less efficient light pattern that causes glare and light trespass. New residential LED street lighting technology has a more efficient lighting pattern that reduces glare and focuses the light directly on the area to be lit (typically corners and mid-block locations). LEDs have better, broad spectrum lighting than traditional high pressure sodium cobra head-style streetlights which spill excessive yellowish-orange light away from the street and into neighboring yards and windows. Because existing poles are not being moved, any unlit areas between poles (corners and mid-block locations) are unchanged. However, due to the uniformity of the light from LEDs, the difference between lit and unlit areas is accentuated. All of our LED lighting is also “Dark Sky” compliant for backlight, uplight and glare. Dark sky is a designation given to outdoor lighting fixtures that meet the International Dark Sky Association’s requirements for reducing the waste of ambient light.
