04/19/2007 ~ Light Emitting Diode (LED) traffic signals, which were originally installed on 17 traffic lights along US Highway One and now cover almost all of Keys Energy Services (KEYS) Service Area, are conserving over 140,000 Kilowatt-Hours* (kwh) of energy per month when compared to their incandescent counterparts.

KEYS, in conjunction with the Florida Department of Transportation (DOT) and the City of Key West Engineering Department, oversaw a multi-year project to install battery back-up systems on 17 traffic signals along US Highway One to provide a minimum of eight hours of continuous, uninterrupted service in the event of a power interruption. The LED traffic signals were installed in conjunction with this project to further conserve the life of the battery since regular incandescent traffic signals would have consumed too much energy and reduced the overall life of the battery.

Given the success of the US Highway One traffic signal project, KEYS has replaced nearly all of the remaining 60 traffic signals it maintains from Key West to Big Pine Key with LED technology to further build upon its contributions to reducing energy consumption.**

Electrical load requirements of LED lights are 10-percent less than that of incandescent lights. Additionally, LED lights produce a more even, easy-to-see light, and have a longer life.

Prior to the LED traffic signal project, the 78 traffic signals that KEYS maintains within its service area consumed over 160,000 kwh of energy per month. Those same traffic signals now consume just over 27,000 kwh per month.

* A Kilowatt-Hour (kwh) is a common unit of electric energy consumption, and the basic unit of electric energy. 1,000 watts consumed for one hour equals a single kilowatt-hour.

** Only the 17 traffic signals along US Highway One have battery back-up capabilities, the remaining 60 traffic signals are solely utilizing the LED technology with no battery back-up capabilities.
