GE LED street lights deliver $146,000 annual savings in Stamford, CT
Following a comparison with induction lighting and LED street lights from several vendors, the city of Stamford, CT, installed over 1000 GE Cobrahead fixtures for an annual saving of $146,000.
However, as more mature LED street lights became available, the city’s evaluation showed that some LED products were able to deliver the high light quality, particularly the color temperature of 4300K, with much less glare and fixture quality needed for the project. “The new LED streetlights are making an important contribution to Stamford’s sustainability efforts, as well as curbing costs and allowing us to light our beautiful streets with a really aesthetically pleasing light source,” said Pippicelli.
The Stamford installation also received help from an Energy Efficiency and Conservation Block Grant (EECBG), on the order of $700,000, while also getting $100,000 from the city itself. Already, the savings in energy have amounted to a $357,000 rebate from Connecticut Light and Power, the electrical provider for the state of Connecticut. The city of Stamford plans to use those funds to install an additional 467 energy-efficient street lights using the GE LED Cobrahead technology next year.
The initial project involved the one-for-one replacement of 254 400W HPS lamps with 157W LED fixtures in the city’s main corridor, which reduced the energy use by over 50 percent. To date, over 1000 fixtures have been installed with zero fixture failures. Annual savings is on the order of $146,000. Since the LED fixtures have an estimated service life of more than 10 years (50,000-hour rated life), maintenance costs for the city also will decrease substantially.
