LED is a highly energy efficient
lighting technology, and has the potential to fundamentally
change the future of lighting in the United States.
Many LEDs - especially ENERGY STAR rated products -
use at least 75% less energy, and last 25 times longer, than
HOW LEDS ARE DIFFERENT
LED lighting is very different from
other lighting sources such as incandescent bulbs and CFLs.
Key differences include the following:
Light Source: LEDs are the
size of a fleck of pepper, and a mix of red, green, and blue
LEDs is typically used to make white light.
Direction: LEDs emit light in
a specific direction, reducing the need for reflectors and
diffusers that can trap light. This feature makes LEDs more
efficient for many uses such as recessed downlights and task
lighting. With other types of lighting, the light must be
reflected to the desired direction and more than half of the
light may never leave the fixture.
Heat: LEDs emit very little
heat. In comparison, incandescent bulbs release 90% of their
energy as heat and CFLs release about 80% of their energy as
Compared to traditional incandescents,
energy-efficient lightbulbs such as halogen incandescents,
compact fluorescent lamps (CFLs), and light emitting diodes
(LEDs) have the following advantages:
Typically use about 25%-80%
less energy than traditional incandescents, saving you money
Can last 3-25 times longer.
Today's energy-efficient lights are
available in the wide range of colors and light levels
you've come to expect. While the initial price of
energy-efficient LED lighting is typically higher than traditional
lighting, they cost less to operate, saving you
money over the life of their life. Many of the newer LED's
last significantly longer than traditional bulbs, so you
won't need to replace them as often.
