While wet-rated and damp-rated lighting is designed to handle contact with moisture, there’s a difference between the two. Wet-rated lighting is safety-rated to be placed in areas with direct exposure to water, including your shower. Fixtures classed as wet-rated are made with waterproof seals to protect the filament and other electrical components from water and moisture. 

Damp-rated fixtures can be used in places with some moisture contact, but not direct exposure. They don’t have the same waterproof seals used in wet-rated fixtures. Damp-rated lighting can be used on your bathroom ceiling or along a wall outside of your shower.

Inspect for burnt-out bulbs, secure connections, and protect from water exposure to maintain functionality.

To maintain your outdoor lighting and prevent major issues, you should regularly clean the fixtures, inspect the wiring and connections, and replace worn or burnt-out bulbs promptly. These simple steps ensure consistent operation and extend the life of your lighting system.

Replacing a pool light costs about $625 per light. If you only need to replace the light bulb, plan on paying about $20 to $100 per light. The largest cost factors include the type of pool light, the number of pool lights needed, and the labor costs in your location. But additional cost factors include work required on existing wiring, other repairs, and the continual maintenance needed to keep your pool light in good working condition after installation.
