WHY CHOOSE ENERGY STAR® LED BULBS
There are two ways to save energy and money: by adopting energy saving habits, such as always turning off lights that are not being used, and choosing products that consume less energy.
WHY CHOOSE ENERGY STAR® LED BULBS?

*LED bulbs are one product that can significantly reduce your energy bill. According to ENERGY STAR®, this new lighting technology is making great leaps, and as research advances, significant gains in their cost-effective and energy-efficiency potential are expected to be achieved by 2020. The quality of LED products varies widely, hence the need to define performance criteria, such as ENERGY STAR®.
PROVEN TECHNOLOGY WITH HIGH ENERGY EFFICIENCY
LED bulbs consume up to 80% less energy, have a long lifespan, and last up to 25 times longer than incandescent bulbs! LED bulbs area available in a wide range of colours and light intensities; they are reliable products that have been meeting ENERGY STAR criteria® since 2010.
ENERGY SAVINGS OF MORE THAN 80%
To show the difference in consumption, we will compare two types of bulbs with a similar light output based on 4 hours of use per day (1,460 hours per year).
In Quebec, the kilowatt-hour cost is $0.08. This means that an incandescent bulb will cost $4.67 (58.4 x $0.08) per year. Replace the incandescent bulb with a LED bulb and your cost drops to $0.82 (10.2 x $0.08) per year.
The total savings with a LED bulb is $3.85 ($4.67 − $0.82) per bulb per year, or approximately 82% cost savings compared to an incandescent bulb!
To simplify the calculation, we used the current domestic (or household) rate of electricity. While the rate will increase over time, so will your savings!
EXTENDED SERVICE LIFE
Even if LED bulbs are more expensive to buy than incandescent or compact fluorescent bulbs, their superior characteristics, including their longer service life, offer greater long-term energy and money savings.
For example, a household 40-watt incandescent bulb generally costs $1 and has a life span of 1,000 hours. A 7-watt LED bulb, which is the equivalent of about 50 watts, costs about $25 and has a life span of 25,000 hours (25,000H / 1,000H = 25)
You may have to replace 25 incandescent bulbs (25 x $1 = $25) over a ten-year period, when you could have paid the same price for one LED bulb and realized substantial energy and costs savings over those ten years.
Now let’s compare an MR-16 halogen bulb and a LED bulb.
The halogen bulb costs about $7 and has an average life of 2,000 hours. The LED equivalent of an MR-16 bulb costs about $20 and has an average life of 25,000 hours (25000/2000 = 12.5)
The service life of the LED bulb is 12.5 times longer than the halogen bulb, so right there you save $67.50 ($7 halogen bulb x 12.50 − $20 LED bulb). And because LED bulbs consume less energy, they’ll save you money in the long run too.
