t & Why
LED Lights?
LEDs (Light Emitting Diodes) are solid light bulbs which are extremely energy-
efficient. When first developed, LEDs were limited to single-bulb use in applications such as
instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor
Christmas lights.
Manufacturers have expanded the application of LEDs by "clustering" the small bulbs. The first
clustered bulbs were used for battery powered items such as flashlights and headlamps.
Today, LED bulbs are made using as many as 180 bulbs per cluster, and encased in diffuser
lenses which spread the light in wider beams. Now available with standard bases which fit
common household light fixtures, LEDs are the next generation in home lighting.
The chart below shows the amount of brigthness in lumes you can expect from different
wattage light bulbs. The LED bulbs require much less wattage than the CFL or
Incandescent light bulbs, which is why LED bulbs are more energy-efficient and long
lasting than the other types of bulb

Why LED Lights?
Durable - since LEDs do not have a filament, they are not damaged under circumstances
when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold
up well to jarring and bumping.
Cool - these bulbs do not cause heat build-up; LEDs produce 3.4 btu's/hour, compared to 85
for incandescent bulbs. Common incandescent bulbs get hot and contribute to heat build-up in
a room. LEDs prevent this heat build-up, thereby helping to reduce air conditioning costs in
the home.
Mercury-free - no mercury is used in the manufacturing of LEDs.
