HOWEVER
or whichever way we put it, there is no denying that
humans are affecting the planet through rampant energy
consumption. Although we don’t intend to, most of us
have become overly dependent on the comfort and
convenience of our appliances without thought that the
energy used in running these often comes from
coal-burning power plants, which release massive amounts
of carbon dioxide (CO2) into our atmosphere.
Although
something simple like conserving energy in our homes may
not have dire global impact in saving the world, it is
definitely a start in making a difference.
Households have the biggest potential for saving energy.
Seemingly inconsequential ways like unplugging
electrical devices after use is one way to cut back on
electricity consumption. Another is by changing the
lighting system in our homes, particularly incandescent
light bulbs that consume lots of energy.
In 2007,
President Arroyo called for a ban on incandescent light
bulbs by 2010 in favor of more energy-efficient ones
such as compact fluorescent lamp, or CFL, to help cut
greenhouse gas emissions and household costs. Once fully
implemented, the country will be the first in Asia to
ban incandescent bulbs.
But what
are CFLs, and how will it help in the conservation of
energy?
Originally known as an energy-saver lamp, a CFL is
designed as an energy-efficient, long-lasting substitute
for the standard incandescent bulb. In a more compact
form, it uses the same principle of the fluorescent tube
in which a phosphor coating transforms some of the
ultraviolet energy generated by the discharge into
light.
CFLs
combine the energy efficiency of fluorescent lighting
with the convenience and popularity of incandescent
fixtures. They work much like standard fluorescent lamps
consisting of two parts: a gas-filled tube and a
magnetic or electronic ballast. The gas in the tube
glows with ultraviolet light when electricity from the
ballast flows through it. This, in turn, excites a white
phosphor coating on the inside of the tube, which emits
visible light throughout the surface of the tube.
CFLs
come in a variety of shapes and sizes but can fit in
almost any standard lighting fixture. Incandescent lamps
may be cheaper but, in the long run, CFLs generate more
savings.
According to the Department of Energy, CFLs consume 70
percent to 80 percent less energy than regular light
bulbs. A 20- to 23-watt CFL can illuminate a room just
as well as a 100-watt incandescent lamp.
Although
CFLs cost more than incandescent bulbs, they last eight
to 13 times longer (about 6,000 to 10,000 hours) in
contrast to incandescent, which have a product life of
750 to 1,000 hours.
Moreover, the CFL is a cool lighting system that emits
lesser heat, thereby saving energy used to cool the heat
generated by lighting.
To get
the most savings, CFLs should replace heavily used
fixtures or lamps that are kept on for at least three
hours a day, such as those used in living rooms, dining
areas and kitchens.
The CFL
also produces maximum light output when installed in a
vertical base-up position.
To
ensure performance and safety, consumers are advised to
purchase only CFLs with the Philippine Standard (PS) or
Import Commodity Clearance (ICC) marks. These marks
indicate that the product has undergone testing based on
PNS 603:1993, which specifies the safety and
interchangeability requirements, including test methods
and conditions, for self-ballasted lamps for general
lighting services.
(The
term “self-ballasted” means the bulb is integrated into
the ballast and cannot be dismantled without causing
permanent damage to the product.)
The PNS
requires the lamp to bear mandatory markings such as the
manufacturer’s name/logo/registered trademark, rated
voltage, rated wattage and rated frequency in “Hz.”
Moreover,
under the Energy Labeling Program of the Department of
Trade and Industry and the Department of Energy, energy
labels are required to be affixed to the product or the
packaging. This guides consumers when shopping for
energy-efficient lamps.
The
energy label contains lamp specifications such as light
output in lumens, power consumption in watts, efficacy
in lumens per watts and average life in hours. When
comparing lamps of the same output, higher efficacy
means greater energy savings.
In a
time when electricity has become a precious commodity,
consumers are clamoring for quality and cost- effective
lighting. CFLs with the PS and ICC mark provide the
answer. |
