A Short Guide to RAB Design Lighting's Ratings and Approvals

Posted by Alafiya Shabbir on Mar 31, 2017 3:21 PM

The lighting world is full of ceritifications and ratings and symbols that can get very confusing if you don't know what they all mean. This is a quick guide to the symbols and certifications you'll find on our website.

IP65 Rated 


The “IP” in the IP rating system stands for “Ingress Protection”. It denotes the ability for a light fixture to block certain levels of solids or liquids from entering the casing.

The first numerical digit represents the solids protection – this ranges from a scale of 0-6, with 0 meaning no protection from outside objects, and 6 being completely dust-tight.

The second digit represents the liquids protection, which ranges from 0-8. In this case, a “5” implies that the fixture can remain fully functional even when under water jets.


IP66 Rated 


Just as explained above, but the second “6” implies a higher level of water protection – this time, against powerful water jets.


cULus or cCSAus Listed

Underwriters Laboratories (UL) and Canadian Standards Association (CSA) are two independent testing and certification agencies. The “c” in front of each certification means that the product meets Canadian standards, and can be sold freely in the country. The “us” implies the same guarantee of the product for the United States.


DLC Approved 


The DLC logo appears on any fixture that has been approved by the DesignLights Consortium. This consortium is a collaboration of utility companies and regional efficiency organizations, whose mandate it is to identify energy efficient solid state lights. Being DLC certified can qualify a fixture for rebates and other incentive programs.


Approved for Wet Conditions

This certification, while similar to the IP ratings, is less comprehensive – fixtures that are approved for wet locations are able to withstand water splashes, drips, or flows near their electrical components, but are not specifically rated to keep out water directly aimed at them.


X-Year Warranty


With each of our fixtures, we guarantee the performance and lighting capabilities for a certain number of years. The warranty symbol on each fixture’s page will describe the length of our promise to you, that the fixture you’re installing will work the way you want it to.


Energy Star

This certification comes from Energy Star, created by the United States’ Environmental Protection Agency. If you see the blue symbol on any of our products, it shows that the LED has achieved a level of energy efficiency that has passed tests for both quality and performance.
