Longer life, brilliant savings!
Lighting accounts for between 5 and 10% of a household's total energy consumption. If all Québec households replaced only one of their incandescent bulbs with a compact fluorescent, the province would save 100 million kWh per year!
Advantages
Variety of models and designs
Compact fluorescents come in a wide range of models and designs and can meet most of your lighting needs, both indoors and outdoors.
Lighting
Bulbs for the Whole House
CFL's are now available in a variety of designs to meet most lighting needs, from the basement to the attic. The choice is yours!

Longer life
Although compact fluorescent lamps (CFLs) are more expensive to purchase initially, their longer life (approximately 10 000 hours) will help you save on the cost of replacing bulbs. They last up to 10 times longer than incandescent bulbs.

Less energy
CFLs use up to 75% less energy than incandescent bulbs, and their light output is equivalent.
Same amount of light
Their light output is equivalent to that of standard incandescent bulbs.
Lighting
Same amount of light
Choose a CFL that provides the same amount of light (measured in lumens) as the regular incandescent bulb it is replacing.
4 to 1 rule of thumb
A CFL consumes approximately one fourth of the energy of an incandescent bulb to provide the same amount of light. Therefore, simply divide the wattage of the incandescent bulb you are replacing by four to find the wattage of the CFL you need.
Lower wattage, same amount of light!

A choice of atmosphere
Cool or warm – it's your choice!
Lighting
A Choice of Atmosphere
The color temperature of a bulb is measured in kelvins (K). The lower the number of kelvins, the yellower the light. The higher the number, the bluer the light.
Cool lighting (functional)
13 W - 850 lm - 4,100 K
Whiter light with bluish tint
If you prefer functional lighting, choose cool white. Many people find it suitable for the kitchen, reading area, workshop or basement, for instance.
Warm lighting
13 W - 850 lm - 2,700 K
Yellower light, similar to incandescent
To reproduce the atmosphere of incandescent lighting, choose soft or warm white.

"Daylight" compact fluorescent (white, with bluish tint): 6,500 K
Incandescent: 2,700 K
"Soft white" compact fluorescent: 2,700 K
Better for the environment
According to a study by the CIRAIG*, CFLs are the most environmentally friendly option for Québec consumers.

ENERGY STAR
® is the international symbol of superior energy efficiency, administered in this country by
Natural Resources Canada. CFLs that carry the ENERGY STAR symbol are among the most energy efficient in their category.
