LED lights consume up to 60 percent less power than our existing lights and are expected to last 20 years. Power savings would be $200,000 per year and maintenance costs would be reduced by $25,000 annually.
The light from our existing fixtures, high pressure sodium lights, is not focused and screens are needed in some cases to prevent light intruding into adjacent dwellings. The lack of uniformity in light results in more street lights being required compared with LED lights.
Research suggests that the superior acuity of LED lights may lead to traffic safety benefits. It is also thought that LED lights produce less up-light into the night sky.
