Flick of a switch at home can set a handful of light bulbs a
glow. Open the car door, or the refrigerator door, and a
light comes on. City streets are illuminated by overhead
lights, stores brightly advertise their presence through
light.
Light, however, comes at a cost, producing the electricity
creates pollution from power plants and greenhouse gas
emissions.
Our current system of light is tremendously inefficient,
incandescent bulbs waste 95 percent of the energy flowing
through them as heat.
LEDs are long-lasting, extremely rugged In addition, they
remain at room temperature, which can cut down energy use
even further by reducing air-conditioning that today offsets
heat from lights.
LEDs are already taking over the market in traffic lights,
automotive tail lights, New Office blocks, airlines and shop
signs and other specialty design applications.
KEY FACTS
LED lights use 1/10th the electricity of incandescent
lights, greatly reducing electricity costs and reducing CO2
emissions
Using incandescent lights is like driving a car that gets
one mile per gallon of gas. It wastes precious energy
resources and
burns money
LEDs contain NO mercury and last 50,000 hours. Using LED
lights greatly reduces landfill and the load on the
environment.
LED lights may seem more expensive at first, but they pay
you back in 1–2 years and keep saving you money and energy
for
every year thereafter (they last for more than a decade of normal
use).
