The park that surrounds the City Hall building in Los Angeles, California has been under renovation for the past eight months. The historic park underwent several “green” changes, including retrofitting the lampposts with efficient LED light bulbs. The light bulbs that previously illuminated the park were 130 watt, high-pressure sodium post-top bulbs. The environmentally unfriendly, inefficient bulbs were replaced with 27 watt LED post-top bulbs. The replacement of LED bulbs provides the park with many benefits consisting of:
-Energy savings of 103 watts per unit
-Reduced replacement and maintenance costs, due to the long lifespan of LED light bulbs
-Improved visibility and enhanced night vision which aids in crime prevention
-Reduced light pollution due to the direct beam of light that LED lights emit
-Instant illumination when the lights are switched on
-Fewer insects because the LED bulbs do not emit an ultraviolet light in which insects are attracted to
In addition, although the entire project of renovating the park cost the city a large amount of money, the park will now begin to save money on electric bills due to the amount of energy conserved by the LED light bulbs.
