If you’ve compared different energy-efficient light bulbs, you may have noticed some are identified as Energy Star products while others have the DLC label. Sometimes buyers get confused about what these two energy-efficient groups are all about and why some lights have the stamp of approval from one group but seemingly not the other.

So, let’s clear the confusion by explaining what these organizations
do and how they are different from each other.

The ENERGY STAR symbol is a consumer icon in the Canadian marketplace. It instantly identifies products that have qualified as high efficiency. ENERGY STAR Canada is a voluntary partnership between the Government of Canada and industry to make high-efficiency products readily available and visible to Canadians.

Canada’s Energy Efficiency Regulations set minimum energy performance standards for energy-using products. The ENERGY STAR symbol identifies products that have met or exceeded technical specifications for high efficiency.

The average amount of money saved in a bulb’s lifetime by using LEDs, compared to the use of traditional light bulbs. The LED bulb costs more initially but it won’t burn out as quickly and it uses less energy and electricity, saving money in the long run.

The Design Lights Consortium (DLC) is similar to the Energy Star program, except it is a regional group that concentrates specifically on energy efficiency in the lighting industry.

The goal of the DLC is to promote energy-efficient lighting in the building sector by influencing public policy and spreading strategies and education. Much of the progress and innovation we’ve seen in the lighting market is thanks to the efforts of the DLC.
