ENERGY-SAVING
LIGHTING OPTIONS

2. Introduction
 The old incandescent light bulb, a mainstay of
homes worldwide for more than a century, will
disappear in the coming decades in favor of
more energy-efficient alternatives. Consumers
might be confused about how modern light
bulbs save energy while emitting the same
quality and intensity of light.

3. The Lumen
 The answer involves the lumen, the standard
measurement of light intensity produced per
watt of electricity. A 100 percent efficient light
bulb—impossible to realize—would produce
680 lumens for each watt of energy. An
incandescent light bulb runs at roughly 1.9
percent to 2.6 percent efficiency in comparison
to approximately 10 percent efficiency in
fluorescent bulbs and 3.5 percent efficiency in
halogen bulbs.

4. Regulations
 Current regulations mandate that
manufacturers list light intensity in lumens and
power consumption in wattage on the
packaging of each light bulb. Consumers can
use this information to compare the efficiency
of certain options and choose the product that
best suits their needs.
