Question:  What is the difference between UL dry, damp and wet location ratings?

Answer: UL Dry Rating: A fixture with a UL Dry Rating may be used in any area, usually indoors, which is not directly exposed to excessive moisture and water.  Any fixture with a UL label that is not explicitly rated for wet or damp applications should be considered a UL dry location fixture.

UL Damp Rating:  A fixture with a UL Damp Rating may be used in sheltered outdoor areas that are protected from direct contact with rain, snow, or excessive moisture (such as ocean spray).  

UL Wet Rating:  A fixture with a UL Wet Rating is suitable for outdoor locations that receive direct contact with rain, snow or excessive moisture (such as fog or ocean spray).
