Energy and maintenance cost savings anticipated during the testing phase have been realized in a 50 to 60 percent energy reduction from the Cree LEDway street light upgrade, equating to a $30,000 cost savings annually. TxDOT records indicate average relamping costs of HPS fixtures along interstate roadways to be between $130 and $150 per fixture with costs to municipalities considerably higher when labor costs are factored in. Approximately 50 percent of HPS fixtures burn out within two years, resulting in the need for frequent replacement that further compounds high maintenance costs. Patti Jett, Public Affairs Coordinator of the City of Baytown states: “The cost savings have directly offset other important budgetary items, while reduced maintenance needs allow staff to work on other projects city-wide. The lighting upgrade has certainly impacted taxpayer dollars in a very positive way.”
Additionally, work crews often must close lanes while relamping traditional street light technologies like HPS, resulting in traffic slowdowns and dangerous conditions. Cree LEDway street lights are tested to provide up to 20 years of use while maintaining the same quality of illumination — a tremendous benefit to municipalities and residents.
