UL Ratings for Lighting and Ceiling Fans: What They Mean

Is it rated for Dry, Damp or Wet? Most of the lights and ceiling fans sold in the United States have been tested and rated by Underwriters Laboratories (UL), an independent product safety certification organization. Some have been tested by Intertek and have an ETL Listed mark.

What exactly do these three ratings mean? What is a damp location versus a wet location?
Here's a guide to everything you need to know about lighting, ceiling fans and UL Ratings.

UL Listed (for Dry Locations)

Often noted just as "UL Listed." A dry location is an indoor area that is not normally subject to dampness. It may include a location subject to temporary dampness provided ventilation is adequate to prevent any accumulation of moisture.

Dry Locations include kitchens, living rooms, dining rooms, bedrooms, foyers, hallways and most areas in bathrooms.

UL Listed for Damp Locations

Only lighting fixtures and fans marked "Suitable for Damp Locations" or "Suitable for Wet Locations" can be used in damp locations. A damp location is an exterior or interior location that is normally or periodically subject to condensation of moisture in, on or adjacent to the electrical components of a lighting fixture or ceiling fan.

Indoor Damp Locations include indoor pool areas, utility rooms and over bathtubs or showers in bathrooms (without risk of direct water contact).

Using Damp Rated Products Outdoors

Outdoor damp rated fixtures can only be used in covered, fully protected locations that are not directly exposed to water, even during storms.

Outdoor Damp Locations include covered patios and covered porches that are fully protected from water, even during storms.

UL Listed for Wet Locations

Only lighting and fans marked "Suitable for Wet Locations" can be used in wet locations, both indoors and outdoors. A wet location is an interior or exterior location in which water or other liquids may drip, splash or flow on or against the electrical components of a lighting fixture or ceiling fan.

Outdoor Wet Locations include open-air decks and patios, uncovered porches, outdoor dining areas, exterior walls, gazebos, pergolas and walkways. Indoor Wet Locations include shower enclosures.
