A typical commercial building's lighting averages 37-50% of its electrical
demand.
1 Billion fluorescent lamps are disposed of every year globally.
That's 50,000 pounds of mercury waste. It takes only 4 mg of mercury to
poison 7,000 gallons of water.
Enough mercury to pollute every gallon of water in the US & Canada.
70% of the nations electricity comes from the dirty coal burning plants.
Average Return On Investment (ROI) is 30-50%.
Energy savings averages 50-80%.
Lifetime of a fluorescent is 20-30,000 hrs; LED is 100,000 hrs.
No maintenance on re-lamping. The storage of bulbs, replacement parts, and
the logistics involved are hidden costs to any re-lamping project.
No low-level radiation or damaging UV rays.
Working temperatures of -20 - 140 degrees LED panels have an average
lifetime 6.2 times longer than fluorescents.
Meets or exceeds Energy Star standards in SSL and meeting the Dark Sky
Standards of the IDA.
Here are a few clear answers from our research & data :
SSL makes a difference in the way people see things.
SSL can make the same item more appealing to the eye.
The color rendering of CLGL SSL is superior to fluorescent lighting.
The general appearance is perceived as cleaner under SSL.
People find themselves more comfortable because of the way SSL mimics almost
all the characteristics of noon time sunlight.
With SSL you have the benefits of healthy natural sunlife without the harsh
UV radiation.
Case Studies:
United Supermarkets changed over 3,600 of their refrigerator and freezer
lights from fluorescent to LED. That equates to a cost savings of $633,000 a
year on energy and maintenance savings.
The expected ROI is 1.8 years. The combined environmental impact of the
47-store retrofit represents an annual 2.9-million pound reduction of carbon
dioxide emissions.
LAX Airport Officials switched to LEDs for their functional and outdoor
lighting. In turn they reduced their annual lighting costs by $55,000 and
their lifetime maintenance costs by $980,000.
An architect for the New Fushin Building in Hong Kong recently decided to
implement LED technology in their office lighting.
He used our panel technology in 600 panels as a test run. In the first year
the savings equaled $22,100 USD on lighting costs.
A cost reduction of $68,000 USD over their lifetime. A savings of $257,200
USD total over the lifetime of the fixtures.
If just 25% of fluorescent lighting fixtures in the U.S.
were converted to LEDs, we could:
l Prevent the release of green house gases equal to
10 million cars.
l Save 15 billion in electricity costs annually.
l Decommission 133 coal burning power plants.
l Reduce carbon emissions by 158 metric tons & avoid
releasing 5,700 pounds of airborne mercury.
They already light up Christmas trees, traffic signals, crosswalks and
vehicle brakes. And they may someday completely displace incandescent
lighting from the marketplace. This is because light-emitting diodes (LEDs)
are at least four times more energy efficient than standard incandescent
bulbs and about 25-50 times longer-lasting; other solid state lighting, such
as flat panel organic LEDs (OLEDs) are not far behind.
"The lighting industry is 'gung ho' about LED technology," says Dr. Guy
Newsham, who leads lighting research at the NRC Institute for Research in
Construction (NRC-IRC) in Ottawa. "They see LEDs as the light source of the
future and have invested vast amounts of money into it."
NRC-IRC's lighting group is working with an industry consortium to study the
potential applications of LEDs and OLEDs in office environments - possibly
the single most important commercial lighting market. "Cost is the biggest
barrier," says Dr. Newsham. "This market is currently dominated by
fluorescent lighting, which is just as efficient as white LEDs and much
cheaper. However, the U.S. Department of Energy predicts that LED prices
will eventually come down substantially and their efficiency will
practically double."
"Although it may be a while before solid-state lighting competes with
fluorescent lighting on a cost-benefit basis," he adds, "this gives us an
opportunity to start identifying office applications where they could
provide extra value for occupants that fluorescents can't."
Customize your colours
For example, unlike fluorescent lighting, it's easy to control the colour
emitted by LEDs. And, LEDs and OLEDs come in more flexible forms than
standard fluorescent tubes. "This means you could use solid-state lighting
in creative ways," says Dr. Newsham. "An office ceiling could glow and
change colour as the outside sky goes from blue to sunset. A cubicle could
change colour if an email arrives. Or, if there's a fire, all of the
cubicles on the evacuation route could turn red to guide people toward the
exit." He and his colleagues will explore whether such functionality is
beneficial for occupants.
So far, the NRC-IRC team has completed an LED colour preference experiment,
which involved a detailed one-sixth scale model of an office. "The
participants were allowed to choose any mix of red, green, blue, warm white
or cool white to see if there's any variation in the lighting colours that
people prefer," explains Dr. Erhan Dikel, who designed the model. "We also
exposed them to a set of fixed spectra to see how they would react. People
generally want a shade of white, but do they want a bluer, redder or
yellower white? LEDs would allow individuals to select their own
preference."
"In future, we may study whether a person's ability to choose a preferred
lighting colour has a measurable effect on their well-being or task
performance over a full day of exposure," says Dr. Newsham. "We might also
explore whether varying the spectrum throughout the day using LEDs can
improve the health of office workers, a potential mechanism suggested by
early explorations into the effect of light on human physiology."
