DENVER – Denver International Airport (DIA) is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures.

The majority of the lights are being replaced with 51-watt LEDs. Combined with other lighting systems in the project, DIA expects a net energy savings of about 45 percent, resulting in energy cost savings of about $327,000 per year. Continue reading

Small Town, Big Savings with LED

The town of Richmond Heights, Ohio, has a little more than 10,000 residents and a whole lot of financial problems. Luckily, Richmond Heights also has the solution to their troubles with LED lights. A solution that will save money they don’t have and increase public safety at the same time.

In 2012, the city’s bill for street and traffic lighting was over $118,000, and they were forced to come up with creative ways to save money. They tasked Police Chief Gene Rowe with the duty of personally turning off every other traffic light in town in an attempt to achieve some of the savings they needed. The chief systematically shut down the lights in a pattern of one on, one off throughout the small town. A total of 54 of the 122 traffic signals were turned off in this move to save money, which is a traffic nuisance and public safety danger to say the least. The total savings of the move amounted to a mere $26,000, leaving lots of fat to cut in the budget still.

City Council of Richmond Heights, Ohio. The cash-strapped town voted to replace its traffic and street lights with LED as a cost-saving measure. A grant will cover part of the cost of the retrofit. Savings are expected to be from 60 to 80 percent.

A Medium-Sized Business Switches to LED Lighting and Reaps the Rewards

The traditional lightbulb had a great run, but times have changed. Today’s LED lightbulbs are far different from their storied counterpart. Traditional lightbulbs are actually extremely inefficient. Most of the energy that they use is wasted in the form of heat. For this reason, incandescent lightbulbs have been a major contributor to climate change and environmental damage over the last one hundred or more years. Thankfully, new technology has emerged to address the problems of this inefficiency in the form of LED lighting. LED lighting isn’t just a cost saver and good for the environment, as it is also very functional and pleasant to the eye!

131772821LED Saving Solutions is a company that helps businesses make the transition to LED. One company that they assisted was Braxton Animal Works located in Wayne, Pennsylvania. Braxton Animal Works has a facility of roughly 8,000 square feet. Since this is a large retail business, a great deal of lighting is necessary. Continue reading

LED Retrofit Saves Mall on Outdoor Lighting

The city of Batesville, Arkansas is a sleepy little town a little less than two hours from the thriving metropolis that is Little Rock. It is a warm and friendly place and a great place to raise kids. In fact, it has been voted one of the 100 Best Small Towns in America. It is also a town that is committed to the community and the environment. The county’s recycling program won the Arkansas community development award and Batesville was selected as the state’s Volunteer Community of the Year. Now the city has made another move towards being a better place to settle: one local shopping centre has replaced old parking lot lights with bright, shiny new LED lamps in a move that will save them over $42,000 a year in energy and maintenance costs, as well as greatly reduce the carbon footprint of both the centre and the town.

Before and after comparison of the Eagle Mountain Shopping Centre parking lot with original metal halide lights and new LED replacements. The LED lights give better light and are saving the centre 65 percent on their outdoor energy use.

When the Eagle Mountain Shopping Centre decided to replace their existing metal halide parking lot lights with LED lamps, the initial estimate of $84,000 may have seemed a bit over the top, but by the time it was finished, that number was the farthest thing from the minds of the building owners as they smiled all the way to the bank.

LED Lighting Doing Great Things For Schools

Recently school use of LED lighting has been the subject of conversation for school officials and policymakers who hope to cash in on the cost savings and other benefits of using LED. Even though this topic is popular now, educational institutions have slowly and quietly been moving to LED lighting for several years with a great reception from teachers, students and administrators.

Philips Lighting Claims R&D System Efficacy Achievement for LED Tube

By: Maury WrightLEDs Magazine

Philips Lighting has revealed laboratory work on an LED-based replacement for fluorescent tubes in which a so called TLED (Tube lighting LED) tube delivered 200 lm/W, including the driver, at a 3000K warm-white CCT. The company said it will bring such a solid-state lighting (SSL) product to market in 18 months to two years.

Philips chose to announce the lab project because of the magnitude of the opportunity for energy savings. Jy Bhardwaj, senior vice president or research and development, said 50% of global commercial lighting uses fluorescent tubes. The best such fluorescent lights operate in the 100-lm/W range so efficiency in that application could double in two years.

Philips_TLED_protoIn the US, fluorescent lights consume 200 terawatts annually according to Philips. The company said retrofit of all such lighting with 200-lm/W tubes would be the equivalent of 50 medium-sized power plants. Continue reading

Walmart Sees the Light for Parking Lots

As more and more businesses look to increase visibility, safety and energy efficiency in parking lots, we take a look at how Walmart started the trend….

By: Roland RisserProgram Manager, Building Technologies Program

I don’t think about parking lots often. Hot in the summer and jammed with frantic shoppers during holidays, I try to spend as little time in them as possible. But because my passion is energy efficiency, I have recently thought a lot about how much it costs to illuminate these spaces and how much energy could be saved with updated lighting systems.

Business owners have long recognized the potential of light-emitting diode (LED) technology to save energy, reduce maintenance costs and improve environmental sustainability. We wanted to take LEDs to the next level by validating the energy and cost-savings potential for LED lighting in retail parking lots and for wide-scale adoption. Continue reading
