Efficiency of LED Lighting vs Incandescent, etc.

Efficiency Benefits Up to 82% in Energy Savings!

According to Flex Your Power, documented studies have proven the energy savings potential of LEDs:

  • Replacing a red incandescent traffic signal head with a red LED unit cuts energy use by an estimated 82 to 93%. The use of LED traffic signals in cities can save 1 million kilowatt-hours (kWh) of energy and nearly $70,000 a year for every 100 signaled intersections replaced. The payback period is approximately two-and-a-half to three years through energy savings alone.

  • There are 100 million exit signs in the United States containing incandescent lamps that consume a total of 20 billion kWh of electricity per year. LED lighting could save approximately three-quarters of this energy. By purchasing 1,000 exit signs for an initial investment of $30,000, a state government could save a net $455,562 over the products’ lifetime. The new signs would pay for themselves in six months.

  • LEDs can replace neon, offering an 80% electricity efficiency improvement.


The benefits of LED lighting technology go far beyond reducing electricity consumption.

Even with a higher initial investment, dollar savings and quality improvements significantly outweigh costs.

LED technology's numerous benefits also include:

  • Long life and reduced maintenance cost
  • High quality light output
  • Increased safety as a result of LED's lower voltage
  • Smaller, flexible light fixtures
  • Increased durability (no filament to break)
  • Lower lighting infrastructure load and cost for expansion

The California Department of Transportation has been involved with the development of LED traffic signal modules for more than a decade. The recent energy crisis played a key role in speeding up the statewide conversion from incandescent lights to LEDs.

The Institute of Transportation Engineer's Future Directions Advisory Committee (FDAC) was appointed to identify and consider the trends and issues facing the Institute and the transportation profession. The FDAC gathered and reviewed information on transportation issues and identified trends:

  • continuing increase in demand for transportation;
    • Population increases and urbanization increase traffic flows
  • traffic congestion;
    • Progarmmable controllers and LED lights can improve communications and monitor/measure and adapt to traffic congestion
  • transportation programs to help meet air quality and energy goals;
    • Think saving energy, reducing greenhouse gases and reducing wasted mileage on the streets
  • greater mix of revenue sources for transportation;
    • Think BLUE LEDs on traffic signals to identify traffic violations!
  • federal government setting the direction for transportation programs;
    • Think funding...and ubiquitious traffic communications for tourism and travelers
  • operations and demand management taking precedence over increasing capacity;
    • Less is better...especially vehicles on the road.  Less oil consumption, less congestion, less accidents, less infrastructure costs...
  • intelligent vehicle highway systems
    • Programmable systems adapt to changing conditions and can even be predictive and take immediate steps to reroute traffic, etc.

Auxiliary Lighting on Motorcycles

Auxiliary lighting on motorcycles

The "Night-time Awareness - Auxiliary Lighting" bill unanimously passed through the Maryland Senate  and the House in April 2008. This Motorcycle lighting legislation enables the front, rear, and sides of bikes to be illuminated using non-outwardly projecting lights. The bill was publicized to raise awareness for the National Highway Traffic Safety Association's motorcycle awareness week.

"Most motorcycle accidents involving another vehicle, they are almost always the fault of the other vehicle, and usually the comment of the other vehicle is, we just didn't see him."

Police Sgt. Dave Ennis adds that "Anything that adds to the visibility of the rider, I think is a move in the right direction."

According to the Federal Highway Administration, in 2000 there were 106,000 crashes from running RED LIGHTS, with 89,000 injuries and 1,036 deaths.

Blue lights above traffic signals  are called "tattletale lights" or "red light confirmation lights." Whenever the traffic signal is red, the blue light is on.

Police previously had to testify that a vehicle was in an intersection when it ran a red light.

Now, officers only have to see the blue light to know the vehicle ran the red signal.

Florida Department of Transportation officials are paying for the lights at intersections on state roads in nine Central Florida counties, reported a representative from the Florida Department of Transportation.

Originally, the DOT put up small white lights at a cost of about $100 each. The DOT is switching to less-expensive blue lights, which are LED (light emitting diodes) that run cooler and need less maintenance.

Running a red light in Florida can bring a fine of $188.50.

Violators also face adding three or four points to their driving record, unless they complete a state-approved driver-safety course.

D.Light, a startup officially announced its products in June 2008.

The company is in the process of moving its offices to Shenzhen, China, from Mountain View, Calif., to manufacture three LED and solar-based lighting products that cost just $10 to $30 and are meant to replace kerosene lanterns.

The Nova will sell for approximately $12 to $25 and one hour of solar charge can provide one hour of LED light on the medium setting.
 
In many regions of India and Africa that are not connected to the electric power grid, kerosene lanterns provide much of the lighting. But kerosene lanterns can be unsafe and cause respiratory problems; they’re also generally pretty dim and are a contributor to greenhouse gas emissions.

D.Light President Ned Tozun tells us that, while no one would argue replacing kerosene lanterns is a bad idea, technologies such as LEDs and solar panels have just started to become cost-effective replacements.

D.Light was founded by Tozun and his business partners at Stanford with  backing from Draper Fisher Jurvetson, Garage Technology Ventures, Mahindra & Mahindra, Nexus India Capital, Acumen Fund, Gray Matters Capital and Michael Marks (the Chairman of Flextronics). D.Light is working with Seoul Semiconductor for its LEDs and plans to produce in “the millions of units” and strongly focused on getting its goods to the developing world first.

In 2007 Cree and Raleigh, North Carolina, Launch Nation’s First “LED City” with Cost-Saving Municipal Lighting

Raleigh Recognizes Greater than 40 Percent Energy Savings as Municipal Garage Switches to LED Lighting.

Cree, Inc., a U.S.-based leader in LED solid-state lighting components, and the City of Raleigh, North Carolina, the anchor city in a rapidly growing metro area, developed a joint, city-wide initiative to test, deploy and promote LED technology focused on a variety of general lighting applications.

The “LED City” initiative will create a “living laboratory” to deliver the economic, environmental and usage benefits of LED lighting to the urban residents.

The first project is focused on validating both the cost savings and technology capabilities of LEDs through an installation of LED lighting in the City’s Municipal Building parking deck.

Both Cree and Raleigh public officials expect the initiative to serve as a model for other cities that are considering implementing energy-efficient infrastructures.

As part of the commitment to creating an “LED City,” Raleigh plans to deploy LED lighting, through its living-laboratory initiative, to serve a number of lighting applications over the next 18 months including:
  • garage and parking lot lights
  • street lights
  • architectural and accent lighting
  • portable lighting
  • pedestrian and walkway lighting

Cree, the City of Raleigh and Lighting Science Group Corporation (OTCBB: LSGP) of Dallas, TX, also announced initial results of the first installation of the LED City initiative. LED-based lighting fixtures, provided by Lighting Science Group, were installed by Amtech Lighting Services in the Raleigh Municipal Building parking deck in December 2006. Progress Energy, Raleigh’s primary electric utility provider, says the floor equipped with LED lights uses over 40 percent less energy than the standard lighting system. Plus, according to Progress Energy’s research, the quality of light in the garage is greatly improved.

“The economic benefits for municipalities to invest in LEDs are clear – they

  • save energy
  • reduce environmental impact
  • improve the quality of light
As leaders in one of America’s fastest growing cities, it’s our civic responsibility to invest in the future and ensure the highest possible quality of life and safety for our citizens in generations to come,” stated Charles Meeker, Raleigh mayor. “We believe that the cost savings and benefits of LED lighting are real and achievable today.”

“Today’s announcement represents a milestone toward large-scale adoption of clean, energy-efficient technologies,” commented Kateri Callahan, president of the Washington, D.C.-based Alliance to Save Energy (ASE).
“Raleigh’s progressive commitment to becoming the first ‘LED City’ will no doubt serve as a model for other cities seeking to improve energy consumption and reduce negative impacts on the environment. We commend Cree and the City of Raleigh for helping support our mission of achieving a healthier economy, a cleaner environment and greater energy security.”

“The City of Raleigh is willing to set the pace, and we invite other municipalities to join us in developing energy-efficient civic centers,” said Chuck Swoboda, Cree CEO and chairman. “This leading-edge effort establishes an important driver for LED adoption within the United States.”

LED City Initiative Yields Benefits Beyond Energy Efficiency

When Raleigh, N.C., the first LED City, and Cree, Inc. turned on new  LEDs in the municipal parking garage, people’s opinion of the quality of the lighting improved threefold.

Survey Shows Public Feels Safer in City Spaces Lit by LEDs


Raleigh exchanged the previous garage fixtures and their dull orange light for LED fixtures with bright white light, and people felt safer. The number of respondents who perceived the garage as “very safe” increased by 76 percent after the LED fixtures were installed, according to a survey by Mindwave Research of Austin, Texas.

Cree produces LEDs that provide a new source of energy-efficient light that can serve as the foundation for cost-effective lighting solutions. Lighting Science Group Corporation of Dallas, Texas, supplied the LED fixtures installed in the Raleigh garage.

“LED technology provides a clear benefit to municipal infrastructure, as well as to the citizens it serves,” said Charles Meeker, mayor of Raleigh. “This survey shows that LEDs can do more than improve light quality. In addition to the proven environmental and energy efficiency benefits the city has already documented, the survey shows that LEDs’ bright white light can help improve public feelings of safety in city spaces.”

The survey results showed that the parking garage generated a more positive reaction from most of the respondents after the addition of LED fixtures:

  • Both men and women felt significantly safer post-installation: 74 percent rated the garage as feeling “very safe,” while only 2 percent did not feel safe. These figures contrast with the pre-installation numbers: Only 42 percent felt “very safe” with the original lighting, and 13 percent did not feel safe.
  • The percentage of respondents who gave the garage an overall rating of “excellent” increased by 100 percent. The number of people who rated it as “poor” decreased from 8 to 1 percent.
  • The lighting quality of the garage was “excellent” according to 86 percent of the respondents, a 258-percent increase from pre-installation respondents. The number of people who rated it as “poor” decreased from 18 to 2 percent.
  • The cleanliness of the parking garage was perceived as “excellent” by 76 percent of the respondents, while only 58 percent rated it this way before the LEDs were installed, showing a 31-percent increase.

Raleigh agrees to become the nation’s first LED City.

The LED City initiative focuses on installing LED lighting, based on Cree’s energy-efficient LEDs, throughout the city to save energy and money and boost the quality of life for its residents by using the best lighting technology commercially available. As a result, the city has improved the energy savings and lighting of its municipal city parking facility, the first of a series of projects aimed at delivering the environmental and economic benefits of LED lighting throughout Raleigh’s “living laboratory.”

Research Note:
The two surveys of 200 people each were conducted on behalf of Cree, Inc. by Mindwave Research, Inc. The pre-installation survey was conducted November 11-13, 2006, and the post-installation survey was conducted February 5-8, 2007.
