Programs to evaluate the energy-saving benefits of LED outdoor lighting have, rightly, attracted lots of attention over the past 12 months. LED street lighting may represent the future but this application is still in its infancy, especially when compared with programs to replace conventional traffic signals with LED fixtures.
Many municipalities could already claim to be "LED cities" in the sense that they have fitted large numbers of LED traffic signal modules and are enjoying the benefits of reduced energy and maintenance costs.
Now, in the largest contract for traffic signals by any US city for over twelve months, more than 70,000 Dialight LED signals will be used to replace traditional incandescent traffic signals throughout the county.
Brian Todd, vice president at Dialight says; "LED traffic signals use 90% less energy and last ten times longer than traditional incandescent traffic signals so this contract will bring major environmental benefits to Miami-Dade County. The additional benefit of our modules is that they can be retrofitted easily into the existing enclosures of the current energy inefficient incandescent lamps."
Dialight, with its installation partner Republic ITS, has been selected as the sole supplier of LED traffic signals for the retrofit of all incandescent traffic signal lamps owned and operated by Miami-Dade County.
Dialight has supplied over two million LED traffic signals across the US over the last ten years. It is also the first company in the US to offer a comprehensive range of LED traffic signal modules that are fully compliant to the new ITE specifications. Dialight products include red, yellow and green modules using state-of-the-art high-flux LED technology.
