This month, I’d like to introduce you to a new technology that is all the more interesting because it saves a lot of money. A little more expensive than other types of bulbs, compact fluorescent lamp (CFL) is well worth its purchase cost. In fact, it is so much more energy efficient than other regular light bulbs that it pays for itself.
– CFL uses 75% less energy than an incandescent bulb; thus, it is possible to replace a 100 watt bulb with a CFL of about 25 watts;
– The lifespan of a CFL is approximately 10,000 hours, 10 times more than that of an incandescent light bulb; CFL is therefore the ideal choice for hard-to-reach fixtures because it will need to be replaced much less often;
– Although the appearance of a CFL is very different from that of a regular bulb, its base is the same; it is therefore suitable for all standard luminaires.
Are the savings possible worth it? Take for example the lighting that illuminates the porch of your home. For safety reasons, many people leave the 60-watt light bulb lit all night, about 10 hours a day, 365 days a year. In accordance with Hydro-Québec’s current rates, this lighting represents an annual bill of approximately $ 13.66. However, if you replace this bulb with a 15-watt CFL, the same lighting will only cost you $ 3.41! By replacing a regular 100-watt bulb outdoors, which you leave on year-round, you could save more than $ 40 a year.
The heat generated by lighting is another factor to consider. Compact fluorescents release 75% less heat. Why then would you spend an additional amount to run bulbs that warm your living room while your air conditioner tries to cool them?
Although the CFL is more expensive to buy, its life is such (10 times higher than that of incandescent bulbs) that it is not only
energy efficient, but also very economical.
