Lighting Tips
The money you spend on light bulbs is only 5 to 10
percent of the total cost of lighting; the other 90 to 95 percent is the cost of
electricity.
- Try motion sensors that turn lights off automatically when everyone leaves a
room. Timers that automatically turn lights on and off can reduce your energy
use increase safety by making a house appear occupied even when people are away.
- Keep fixtures and bulbs clean. Dirt can absorb as much as 50 percent of a
bulb's light output.
- Use one bulb instead of multiple bulbs whenever possible. A single 100-watt
incandescent bulb produces the same amount of light as two 60-watt bulbs and it
uses 20 percent less energy.
- Long-life incandescent bulbs last two to three times longer than a standard
bulb. Compact fluorescent lamps last up to ten times longer. Light colored walls
and surfaces reflect light while dark colors absorb light. The same light
fixture in two different rooms will provide different levels of light on a
reading surface.
- Translucent lampshades provide more light than solid colored shades. Use
dimmers or three-way incandescent bulbs to control the amount of light you need
in a room. Dimming the lights to half the illumination cuts energy consumption
almost in half.
- Turn off lights when nobody is home. Use a timer to ensure you don't forget.
- Use daylight whenever possible, rather than turning on redundant overhead
lighting.
CFL
Lamp manufacturers have applied the latest technology to make compact
fluorescent light bulbs more attractive, reliable, versatile and affordable than
ever. The excitement spurred by today's breed of compact fluorescents is
well-founded. These new bulbs are:
- Convenient. Regardless of how often they are switched on and off,
compact fluorescents enjoy a long life, with one bulb able to outlast six to ten
incandescent bulbs. You spend less time on the ladder switching bulbs -- and
less money replacing burned-out bulbs.
- Appealing. Compact fluorescents now have rapid or instant start, no
flicker and are available with a comforting, soft-white quality of light.
- Versatile. Compact fluorescents are available to fit most any
fixture, from reading lamps to table lamps or floor lamps. There are also
compact fluorescent vanity bulbs, floodlights or outdoor bulbs.
- Efficient. Most incandescent and halogen bulbs waste 90 percent of
their energy generating heat. No so with the compact fluorescent, which uses 75
percent less energy to produce the same amount of light. You can save on energy
costs by using a lower-wattage compact fluorescent and still enjoy the same, or
even more, light.
- Economical. The compact fluorescent costs more up front, but the
savings add up in the long run. Incandescent bulbs typically last 1,000 hours,
while halogens last 2,000 hours. A compact fluorescent bulb will give you 6,000
to 8,000 hours of light.
Battle of the Bulbs
- A 18 watt compact fluorescent = a 60 watt incandescent, saving $16.80 in
energy costs.
- A 22 watt compact fluorescent = a 75 watt incandescent, saving $21.20 in
energy costs.
- A 27 watt compact fluorescent = a 100 watt incandescent, saving $29.20 in
energy costs.
- A 30 watt compact fluorescent = a 150 watt incandescent, saving $48.00 in
energy costs.

Fire Danger In Your Home?
If you own a halogen torchiere floor lamp, you may be getting more than you
bargained for. More than 50 million halogen torchieres have been sold in the
U.S. since the late 1980s. Their standard light source is a high-wattage halogen
lamp, which produces a clean white light that many people find attractive. These
lamps are popular, inexpensive and dimmable -- but they are also highly
inefficient and extremely dangerous.
Halogen torchieres are a serious fire hazard, according to the Consumer
Product Safety Commission. They estimate that the lamps have been linked to more
than 350 fires, 30 deaths, and 114 injuries in the U.S. in recent years.
The halogen torchiere heats up to 1100°F, which can ignite nearby flammable
objects within minutes. Demonstrations have shown that when a frying pan was
placed on the torchiere fixture, it cooked an egg within three to five minutes.
Another serious problem with halogen torchiere lamps is their extreme
inefficiency. Amazingly, a halogen torchiere lamp costs more money in one year
to operate than its original purchase price. That's because these lamps consume
as much energy as a typical refrigerator and 95 percent of this energy is wasted
electricity.
Halogen torchiere lamps yield one watt of visible light and nine watts of
heat for every ten watts of power consumed. Put another way, you get one
kilowatt hour worth of light for every ten kilowatt hours that show up on your
PUD bill. Dimming the torchiere may reduce light output, but it also reduces the
lamp's efficiency.
The safe alternative to a halogen torchiere is a cool-burning,
energy-efficient compact fluorescent torchiere. While energy efficient lights
may cost a bit more up front, they pay for themselves quickly because they use
less energy. A compact fluorescent torchiere uses up to 85 percent less energy
than the comparable halogen fixture and is six to eight times cooler, a
difference of up to 900° F.
