What is the cheapest energy? The energy that is not used!

energy-efficient lighting

LED light bulbs last up to 100,000 hours, depending on the quality of the diode and the application.

How to choose lighting? It is easy: less wattage, more ambiance! Although lighting represents less than 10% of the energy consumed in the home, the gesture is so simple that it will always pay off: install directional lighting above places of activity. This will limit energy waste.


Opt for LED (light emitting diode) bulbs, both inside and outside the home. LEDs are very robust and durable, their lifespan is 25 times longer than that of conventional incandescent bulbs. For an equivalent light output, they are 16 times more energy efficient. Moreover, they are recyclable and toxin free.

You can also turn to halogen bulbs as a good alternative. They provide a “warm” light and a steady brightness throughout the whole lifespan of the bulb. The light emitted by the halogen bulb is comparable to the natural light of day. The choice is less “green” than the LED bulb, yet it is also toxic free and is more accessible to buy than the LED. Like the LEDs, halogen bulbs are more efficient and longer lasting than conventional incandescent bulbs. In all cases, opt for bulbs that are ENERGY STAR® certified; you'll be guaranteed energy efficiency and durability.

What is the Rolls Royce of lighting? Solar tube wells. Not to be confused with traditional skylights (a window to the sky that causes heat loss and creates problems with condensation). Solar tube wells are an ideal solution: highly waterproof, they offer a warm, bright light at no cost, they are simple to install and do not cause the greenhouse effect in summer. They are perfect in small living spaces with few windows.
