Outdoor Lighting: LED Roadway wins Edmonton project, Kingsun supplies Shenzhen (Updated)
LED Roadway Lighting will supply 2580 SSL street lights to Edmonton, Canada, Kingsun Optoelectronic completes LED highway lighting project in Shenzhen, China, and Las Vegas and UK SSL updates.
In a mix of new and retrofit applications, LED Roadway Lighting is supplying the city of Edmonton, Canada with 2580 Satellite series LED luminaires. Kingsun Optoelectronic has completed one of the first large-scale LED roadway lighting projects in China deploying solid-state lighting (SSL) along a 120-km highway. Las Vegas, Nevada has begun an LED retrofit project that could reach 50,000 street lights, and we have more details on the Bristol, UK project that utilizes Philips SpeedStar luminaires.

In Edmonton, the city projects that the SSL project will deliver $2.6 million in energy savings over the expected 20 year life of the luminaires. The projection is based on 51% savings over the high-pressure sodium (HPS) fixtures that are currently in use. The local electric utility Epcor Utilities worked with the city to specify the LED luminaires.
Over the 20 year period, the city projects a reduction of 12,880 tonnes of greenhouse gas emissions. Moreover the aggregate electricity savings total 16,000,000 kWh.
”This project represents one of our largest deployments in Canada, and reinforces our message that municipal and other users are interested in reliability and are serious about conducting a total life cycle cost evaluation,” said LED Roadway Lighting CEO Charles Cartmill. “We are very excited about the future, and for this current opportunity to supply our fixtures to the City of Edmonton.”
Kingsun supplies 10,000+ luminaires
In Shenzhen, China, Kingsun has supplied more than 10,000 SSL luminaires for a roadway lighting project along a total 120-km stretch of highways with three traffic lanes and an emergency lane in each direction. The project includes both pole-mounted roadway lights and tunnel lights installed on the Jihe highway number G15, the Nanguang highway number G9411, the Longda highway number S318, the Yanba highway, and the Dameisha tunnel.

The Shenzhen project was a new roadway lighting project rather than a retrofit. Kingsun supplied 270W and 300W RL2R Apollo LED luminaires for the roadway where it’s likely that 450W HPS lights would have been required for the project. Kingsun said the LEDs will deliver 60% energy savings.
The roadway lighting is deployed in a median belt that isolates the opposing traffic lanes. Each pole includes arm mounted luminaires on each side. Kingsun says the average illumination is more than 20 lx.
Las Vegas and Bristol
The city of Las Vegas, Nevada just announced that work had begun on a project to replace 6000 street lights with LED fixtures. The city expects the project to deliver $400,000 in energy savings annually – a reduction of 8,000,000 kWh.
The city’s public works project is managing the project that was funded by the combination of $2.9 million in federal energy conservation bonds, and a $400,000 grant from the state of Nevada. Crescent Electric Supply Company and Transcore are partnering on the installation work. The city plans to ultimately upgrade its entire inventory of 50,000 street lights.

In a recent outdoor lighting story, we mentioned an LED lighting installation in the Bristol, UK area where SSL has been deployed at the busy Hicks Gate roundabout in Kenysham between Bath and Bristol. Philips subsequently announced its participation in the project and supplied pictures of the uniformly-lit traffic circle.
Philips noted that the SpeedStar luminaires will reduce energy and maintenance costs for Bath and the regional North East Somerset Council. But it’s the quality of light that receives top billing. “SpeedStar was at the core of a Philips lighting scheme that improved the experience of road users at the Hicks Gate roundabout,” said Keith Showering, Team Leader Highway Electrical and ITS, Environmental Services, Bath & North East Somerset Council. “Philips’ specialist application of LED technology meant that Bath and North East Somerset Council were able to save energy and reduce maintenance costs without compromising on light quality or driver safety.”
