Lighting represents about 5% of a home’s energy consumption.Selecting the right light bulbs and lamps and making good choices are ways to help control energy consumption more effectively.

Some advice on lighting to help reduce your energy consumption.

Given the vast selection of lighting fixtures available on the market, it is essential to determine your needs before making your choice, for both indoor and outdoor lighting. Whether you’re looking for direct or diffuse lighting, a reading lamp or a particular lighting ambience, choose the best ratio of energy consumed to brightness provided.

Incandescent light bulbs waste energy

One incandescent light bulb (i.e. a regular light bulb) only uses 5% of its energy to produce light and wastes the rest on heat. Therefore, it is not the best choice when trying to save energy!

Safe handling

Florescent tubes and compact fluorescent bulbs contain mercury, a highly toxic substance. Therefore, they must be handled with care. They must also be discarded in an ecological manner.

  • Compact fluorescent bulbs are 98% recyclable. There are many locations where they can be recycled. Call you municipality to find out where you can drop them off or where your hazardous household materials sites are located.
  • If you would like to learn how to protect yourself when compact florescent bulbs break, the following site provides a very useful guide that deals with the health risks associated with mercury exposure in this situation. It was published in 2009 by the Institut national de santé publique and is entitled: Avis scientifique sur les risques pour la santé de l’exposition au mercure lors du bris d’ampoules fluo-compactes. It is only available in French.

Energy Efficient Choices

It is possible to light your home for less by replacing your incandescent bulbs by LED, compact fluorescent or halogen bulbs. It is recommended to use ENERGY STAR® certified bulbs if you opt for compact florescent or LED bulbs.

LED bulbs use energy very efficiently (80% in energy savings when compared to incandescent bulbs) much the way compact fluorescent bulbs do (70% in energy savings when compared to incandescent bulbs). In addition, they last much longer which means that they help reduce the amount of waste produced.

Here is the useful life of the different bulbs:

  • Incandescent: 750 to 1,000 hours
  • Halogen: 1,500 to 3,000 hours
  • Compact fluorescent: 6,000 to 10,000 hours
  • LED: 25,000 to 100,000 hours

Install electronic dimmers

By using a light dimmer, you reduce your energy consumption and extend the life of your light bulbs. Depending on the decrease in intensity, you can save from 5 to 50% in energy costs.
