CFL Light Bulbs and LED Bulbs
The future
of lighting: Compact Fluorescent Light bulbs (CFLs) and Light Emitting
Diodes (LEDs)
Household
lighting typically accounts for 10% of your
electric bill. While
this might not seem
like a big number, consider this: if your electric bill is $80 a month,
you're paying about $96 a year for just the lighting in your home!
Changing your light bulbs can significantly reduce your
long-term energy costs.
Traditional
incandescent bulbs convert most of their energy
into heat instead of light, wasting electricy on unnecessary warmth. Compact fluorescent lights
(CFLs) and light
emitting diodes (LEDs) on the other hand, convert most of their energy
into
what you want most: light. Both CFLs and LEDs are
also designed to last
years longer than the average incandescent bulb, reducing both energy
and
replacement costs.
Compact
Fluorescent Lights (CFLS) and Light Emitting Diodes
(LEDs) have risen in popularity in recent years due to their longevity
and
energy-efficient design. These
bright, compact lights are designed to reduce your energy consumption
without
sacrificing light or productivity. In
fact, manufacturers have created CFLs that are designed to fit into
your exiting
light fixtures, easing the transition from traditional incandescent
bulbs to
more energy-efficient alternatives. But
what are CFLs and LEDs? And how do they
work?
Compact
Fluorescent Lights (CFLs)
Compact
fluorescent lights (CFLs) are created by taking a
traditional fluorescent tube and bending it into a compact
design that fits
easily into ordinary incandescent fixtures. In general,
CFLs
use up to 75%
less electricity than conventional light bulbs while still producing a
comparable
amount of light. For example, a compact fluorescent bulb that
uses 27 watts of electricity has the same light output as
a 100 watt incandescent bulb.
Unlike
typical fluorescent
lights, however, compact fluorescent lights do not flicker. Furthermore,
CFLs produce
the same, if not better, quality light as
conventional incandescent bulbs. This
means you get brighter, sharper light for much less energy.
CFLs
also last much
longer than incandescent lights, meaning
you won't need to replace them as often as ordinary bulbs. In
general, for every ten incandescent light
bulbs you replace, you would only need to replace one CFL. Not only
does this save money, it also
reduces your waste.
Light
Emitting Diodes (LEDs)
While
Light Emitting Diodes (LEDs) have been around for
decades in household appliances, computers and clocks, they've only
recently gained
popularity as energy-efficient alternatives to incandescent bulbs.
LEDs are tiny lights produced by moving
electrons in a
semiconductor. There
is no burning gas
or filaments so LEDs are more durable and produce little to no heat. Their small size also makes LEDs
extraordinarily resistant to weather and can even be waterproofed for
more
extreme conditions.
A
single LED is
rather small, but imporvements in technology have allowed for the
combination of bunches of LEDs together to create consumer products
ranging from
powerful flashlights to Christmas lights and lamps. Large
groups of LEDs have been used to
replace traffic lights and brake lights in cars. Since
they are designed to last for many years,
these unique lights almost never need to be replaced and can withstand
more
extreme conditions than ordinary bulbs.
Just
like compact fluorescent lights, LEDs are also incredibly energy
efficient and
use only a fraction of the energy needed to power a single incandescent
bulb. In fact, LEDs use 1/50 of the
energy of a standard bulb and last 10 times longer than their CFL
alternatives. A typical LED bulb can last up to 15 years
without needing to be changed! They are not as versatile
in traditional light fixtures, however, and are generally more
expensive than
compact fluorescents.
