Case Study: City of Centennial, Colorado Saves More than $50,000 a Year with Dialight LED Traffic Signals

Installation Snapshot
- Total # of red, green, yellow balls & arrows - 1,545
- Replaced - 150W incandescent with 8W LED
- Total # of pedestrian signals - 233
- Replaced - 50W incandescent with 6W LED
- 572,000kwh annual savings
- $56,000 energy & maintenance savings

As part of a city-wide sustainability initiative, officials in Centennial, Colorado recently completed a project to upgrade each of the city’s traffic and pedestrian countdown signals from traditional incandescent units to Dialight’s high-efficiency, low-maintenance ITE-compliant LED traffic signals. The project, funded by the U.S. Department of Energy’s Energy Efficiency and Conservation Block Grant Program (EECBG), not only improved visibility for drivers and pedestrians, but is expected to save the city $50,000-$60,000 a year in energy and maintenance costs.

Modern City, Progressive Planning

Appropriately named in honor of its citizens’ September 2000 vote to incorporate, the City of Centennial is not only one of the youngest cities in the State of Colorado, but also the safest. With a vibrant community that blends the convenience of city living with the beauty of semi-rural neighborhoods, Centennial has been named Colorado’s safest city for six years in a row. Home to nearly 110,000 residents, the city’s backdrop against the picture-perfect Rocky Mountain skyline makes it one of the most beautiful in the Great American West.

In a progressive move intended to improve driver and pedestrian safety and reduce energy consumption and expenses, the city has recently completed a full replacement of its out-dated incandescent traffic signal balls, arrows and pedestrian indications with Dialight’s ultra-energy efficient ITE-compliant traffic and pedestrian signals.

“Safety, reliability and overall brightness were significant concerns,” said Craig Faessler, P.E., City Traffic / Transportation Engineer with the City of Centennial. “But, so were the energy consumption and maintenance costs. An upgrade to all-LED addressed all of these issues.”

In addition to the fact that some of the faded lenses were at least 20 years old – as old as the signals themselves— the units consumed an exorbitant amount of energy and demanded nearly continuous maintenance with regular bulb changes to keep motorists and pedestrians safe. After a competitive bid process, Centennial chose Dialight units provided by Traffic Signal Controls, Inc., a Colorado-based Dialight distributor, for their efficiency and affordability.

New Dialight StreetSense™ Series LED Street Light Delivers High-Output with Precision Optics for Ultra-Low TCO and Maximum Energy Savings

Made in U.S.A. to Meet Buy American Act Featuring Dialight’s Exclusive Driver Technology for Optimum Performance and Long-Life Reliability

Farmingdale, NJ (January 25th, 2011)—Dialight (LSE: DIA.L), the innovative global leader in LED lighting technology, today unveiled its latest innovation in LED roadway and area lighting with the new Dialight StreetSense™ Series LED Street Light featuring Dialight’s exclusive optics technology for precision light placement along with maximum energy efficiency and reliability for ultra-low total cost of ownership over the lifetime of the fixture.

The new luminaire is designed for easy changeout from existing HID fixtures to help municipalities and commercial property owners meet sustainability and energy efficiency goals and reduce maintenance costs. Each unit is manufactured at Dialight’s Roxboro, NC production facility to meet the Buy American requirements for projects funded through the American Recovery and Reinvestment Act of 2009 (ARRA).

Delivering up to 75 lumens per watt and 70 percent lumen maintenance over 60,000 hours, the new StreetSense fixture leverages Dialight’s own proprietary integrated precision driver design to maximize performance and thermal management within a compact and lightweight housing. Driven at just 350mA for long-life LED performance, the high-output StreetSense streetlight utilizes the latest lighting-class Cree XLamp® XP-G LEDs and operates at 100-277V to provide a superior quality, cool white light with a CRI of 70 and 6000K CCT.

“This fixture incorporates a number of Dialight’s industry-leading innovations, including our exclusive precision optics and unique angled design for more precise light placement that minimizes light trespass, especially in residential areas,” said Roy Burton, group chief executive at Dialight. “And, our exclusive in-house driver design ensures maximum energy efficiency and thermal management backed by Dialight’s legendary reputation for innovative power supply optimization and reliability.”

The new StreetSense fixture is available with optional dimming capability and/or photocontroller for dusk-to-dawn operation. With instant-on and a power factor greater than 0.95, the StreetSense fixture provides flexible control options in a rugged, cast aluminum housing with UV and abrasion resistant polycarbonate lens (glass options available upon request). Available now with Type III optics; Type II, IV and V models will soon be available.

Dialight Unveils First-Ever 90mm LED Low-Beam to Meet SAE J1455 Ruggedized Spec

Dual-Voltage Unit Delivers Exceptionally Long Life and Energy Efficiency for Forward Lighting on Mass Transit Vehicles and Commercial Trucks;Baltimore Transit Authority first customer to install with 42 New LED-Equipped Busses on the Road; Manufactured in Roxboro, NC to Meet ‘Buy American Act’

Farmingdale, NJ (January 10, 2011) – Dialight (LSE: DIA.L), an innovative global leader in LED lighting technology, today announced the launch and immediate availability of its new LED 90mm Low-Beam Headlamp for mass transit vehicles and commercial truck applications. The Dialight Low-Beam meets FMVSS108 and is the only such product on the market designed to meet the stringent SAE J1455 specification for ruggedized applications, making it ideal to withstand the harsh operating conditions for municipal busses and commercial truck fleets.

“This Dialight exclusive is a real game-changer, not only for its rugged design, superb energy efficiency and long life, but also the advanced optical system that ensures a more uniform, directional beam for added safety and visibility,” said Roy Burton, Dialight’s Group Chief Executive. The product is the industry’s first LED reflector-based design that utilizes a reflective bowl to create a more uniform, consistent light beam that maximizes output and minimizes light loss to improve visibility and safety for oncoming traffic.

“Backed by our 7-year warranty, this product promises to deliver dramatic cuts in maintenance costs for municipalities and commercial operators,” Burton said.

Drawing less than 14 watts, compared to the typical 40-55 watts with traditional HID headlamps, the Dialight 90mm Low-Beam reduces energy consumption, relieves wear and tear on the vehicle alternator and dramatically reduces maintenance costs by eliminating frequent change-outs. With a 7 year warranty, the Dialight LED Headlamp also provides peace-of-mind that the lights will not require re-lamping until the first rehab, compared to the incumbent technology which would only last 500 hours.

The Baltimore (Md.) Transit Authority is the first customer to receive 42 new busses all equipped with the new LED units, which provide an exceptionally long life expectancy in excess of 10 years or 25,000 hours of output.

Designed for OEM integration or easy retrofit from halogen/HID units with no retooling, the Dialight LED unit leverages the brilliant white light and exceptional performance of the Lumiled LUXEON® Altilon LED. Engineered to withstand extreme temperatures and deliver superb thermal management, the Altilon is the solid-state technology of choice for high-performance automotive applications.

As an added bonus for transit authorities looking to leverage the energy- and maintenance-savings of the 90mm Low-Beam, the product is assembled in the U.S.A. at the Dialight manufacturing facility in Roxboro, NC and meets the requirements of the Buy American Act for federally funded projects.
