10.Paybacks can be relatively short with LED Street-Lights
But it's dependent on the "1+1+1 rule"
LED payback = Hours of Use + Reduced Use of Electricity + Rebates
Rebates may be the least important of the three. High hours of use and high cost of electricity will dwarf the benefits of a rebate.
Everyone likes a rebate. We have created many proposals where payback was under 1 year even without rebates. Contact us and we can help walk you through the math.
11.Reduced Light Pollution
Traditional street lights may illuminate streets and sidewalks at night, however, they are notorious for light pollution. Light pollution is misdirected and excessive outdoor lighting. As countries and cities become more developed, the constant demand for street lighting increases the threat of light pollution.
Light pollution occurs in different ways including light trespass (light spill), sky glow, glare, and light clutter. It affects the environment as carbon dioxide is released into the atmosphere. The International Dark-Sky Association states that each year, about 12 million tons of carbon dioxide are released by invasive night time lighting. The association also estimates that 30% of all street light is wasted.
Light pollution also affects the lifestyle of mammals, birds, amphibians, and insects by causing disorientation and affecting their migration, sleeping, mating, and feeding cycles. LED technology has addressed the light pollution problem by developing light fixtures that focus light only where it is required.
