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.

Cold weather can cause older incandescent Christmas lights to fail by causing cracks in the finish or the glass itself. Modern LED lights are affected in the opposite way and perform even better as the temperature drops. 

Your maintenance needs revolve around the type of foundation you choose, as well as how you furnish or decorate it. Patios require little else other than the occasional hose-down, but decks and other wooden structures will require annual power washing and sealing. You may also need to restain the wood every two to three years.

Adding a solid roof rather than building a pergola or leaving the space open will make maintenance much easier. Without a roof, you will need to spend more time sweeping, washing, and covering your furniture to protect it from UV bleaching.

Yes, professional landscape lighting is typically worth the investment. Installing a lighting system can improve your home’s curb appeal, safety, and security, and it can also deter burglars. It adds value to your home by creating a brightly-lit outdoor space you can use after dark and making the property more appealing to potential buyers. According to the National Association of Realtors, landscape lighting can add up to $2,500 to your home’s value, and on average, this type of home improvement has a 50% return on investment.
