There are approximately 3,300 street lights lining our City roadways. These lights are a mixture of top-of-the-post mounts which you see in the downtown and Spring Lake area, and cobra heads style fixtures which are located in the majority of our residential neighborhoods; both of these fixtures utilize a type of lamp called high pressure sodium (HPS). These lamps emit a yellow/orange light and vary in their power consumption depending on the wattage of the lamp in use; typical wattages are 70, 100, 150, 200 and 250.
On July 5th City crews began replacing the HPS street light fixtures from CR 98 to West St. with energy efficient fixtures that utilizes light emitting diode (LED) technology; this effort is being done to help reduce the maintenance and utility costs associated with the lighting of our roadways. This project, which is being funded by an Energy Efficiency Conservation Block Grant (EECBG), will allow us to install approximately 1,400 of the LED fixtures in our City.
One of the more evident changes that you will notice between the two types of fixtures will be the color of light they produce. While the physical attributes of the fixture themselves will be very similar, the orange/yellow tint that is currently created by the HPS lamps will now be replaced with a more apparent white light. Furthermore, the utility cost to operate a new LED fixture is less than half of its HPS counterpart and can last up to 3 times longer. This project will produce a savings of approximately $40K a year in reduced utility charges alone. Other savings will include a onetime PG&E rebate of $50 to $150 for every LED fixture installed (this amount varies on the wattage used), and a reduction in maintenance costs associated with employing this type of technology.
In an effort to get community buy in, City crews installed 80 of the LED fixtures in various locations of the City last year; feedback we received from an informal survey was very positive. Of the 381 responses received, 91% approved of the new lights, 4% disapproved, while 5% had no comment.
