Retrofitting Street Lighting with Energy Efficient LED Lamps Reduces Costs

Now that the weather is warming up, it is the ideal time to upgrade to the latest energy-saving outdoor lighting technology. With the upcoming autumn season comes reduced sunlight. Because of this, street lights are on overtime throughout the fall and winter seasons.

Cities should start inspecting or optimizing their lighting before the fall hits. While maintaining and changing lamps, it’s the perfect time to assess new lighting system options. For instance, poles may need to be replaced as well as fixtures to more energy efficient LEDs.

Energy Efficient Lighting Reduces Carbon Footprint

Many local streetlights today have fixtures that are about 25 years old and may perhaps be in dire need of an upgrade that can save cities money through the installation of more energy efficient lighting systems. More and more people are moving into cities, continuing the ever-increasing growth of urban areas across the country. This population boom causes a city’s carbon footprint to rapidly grow along with it. Switching from High Pressure Sodium  or Metal Halide to LED lighting solutions can help mitigate the production of environmentally harmful carbon byproducts brought about by exponential population expansion.

As cities continue to develop they will be required to provide long-term livability solutions through infrastructural changes. LED lighting is the next evolutionary technology for cities to adopt moving into the future. Many cities, including Chicago, already have started plans on installing LED lighting systems.

Over 25 million streetlights in the US consume 40% of cities’ electricity use, equal to 2 million households each year with CO2 emissions equal to 2.6 million cars. Changing all US outdoor lighting to LEDs could prevent the emission of as much as 90 million metric tons of CO2.

Why LED Lighting Systems

Why is LED Lighting so attractive? LEDs have significantly decreased operating costs and simultaneously increased the lifespan and efficiency of the fixture. Making lighting more energy efficient is known as lighting retrofitting. Although switching to LED lighting alone can result in 50-70% energy savings, it is not sufficient enough to meet global targets for savings and sustainability.

Adaptive and inter-operable lighting is essential to bring cost and performance improvements to a next level of significance. Enabling LEDs to dynamically change lighting levels in response to local conditions can generate total system energy savings of up to 80%. These responsive or “Intelligent” sensor lighting systems allow for lighting to be activated only by motion, saving money and improving efficiency.
