If you’ve worked with electrical products before, you may have noticed a label that a CSA or UL label on the packaging. If you are wondering what they mean, we are about to tell you.

Underwriter Laboratories


UL stands for Underwriter Laboratories, which is an organization that develops and evaluates safety standards for lighting and other electrical products in the United States. When a product includes the UL logo, it means that it has been tested and verifies for safety by UL. 

The packaging may also include location-specific labels. These are important to understand where you can use your decorative elements. A few you should pay attention to when decorating for the holidays season include the following. 

  • Dry Location– Applies to fixtures designed for indoor use.
  • Damp Location– Indicates that the light fixture can be used outside in an area protected from direct contact with water
  • Wet Location– Signifies that the lights can come in direct contact with water, and elements, such as showers and saunas. 

Canadian Standards Association

CSA stands for the Canadian Standards Association. The CSA Group is an internationally recognized organization that tests electrical and mechanical products and those that might be considered riskier. A product that has the CSA mark has passed its safety standards.

What is the main difference between the two labels? 

CSA and UL are very similar. The UL applies to just the US, while CSA is recognized globally.  A combination mark indicates that the product is in compliance with both Canadian and U.S. requirements.
