More than 141,000 street lights have now been switched to LED equivalents.
As LED lighting becomes the industry norm, the number of Councils and City departments trialling and installing LED street lights has increased significantly.
The market has shifted so quickly thanks to technology advances that the City of Los Angeles last year completed the world’s largest LED street light replacement project.
More than 141,000 street lights have now been substituted with their LED equivalent bulbs and fixtures. LA is certainly not the only one switching to LED street lighting, there are many other California cities, big and small, doing the same. March last year saw Las Vegas finish outfitting 42,000 LED street light fixturesl. City of Texas announced plans to install 35,000 and San Antonio another 20,000.
Los Angeles partners Clinton Climate Initiative and C40 Cities Climate Leadership Group have provided support to jump-start the market. Navigant Research recently predicted that shipments of the LED street lights will increase to more than 17 million in 2020.
The City of LA estimates that it will see over $7 million USD in electricity savings and over $2.5 million USD in maintenance costs savings annually with the switch to LEDs. The street lights can account for up to 40% of a city’s electricity bills according to Eric Woods from Navigant Research.
The LED street lights used in Los Angeles include CREE’s XSP series and LEDway series, Hadco RX Series (a Philips company) and Leoteks GC Series that consume around 60% less energy and last a significantly longer time than the high pressure sodium lights they replaced.
Driving innovation and lower prices are key components of the LED lighting industry, and as LEDs improve the energy savings are being realised and continue to increase. A city planner from LA estimated that the LED fixtures would yield just 40% saving over the HPS units, but in fact the actual delivered results are over 63 percent.
A LED fixture installed on a residential street light in Los Angeles, in 2009, cost an average of $432, illuminated at 42 lumens/watt, lasted 80,000 hours, and came with a 5-year warranty. By the end of 2012, that same fixture cost an average of $245, illuminated at 81 Lm/W, lasted at least 150,000 hours, and came with a 7-year warranty.
In the second phase of its LED replacement program, Los Angeles will retrofit 70,000 decorative street lamps. The city is testing and evaluating LED and induction fixtures for use in the 400 different styles of such lamps operating in Los Angeles. The city also announced, in April, that it would expand a pilot program with GE Lighting to measure the performance of GE’s LightGrid Outdoor Wireless Controller units. The technology enables remote monitoring and control of individual street lights.
