Whether it's a commercial building or a residential home, both of these structures will require some sort of wall lighting, either interior or exterior. The type of fixtures that you need depends on where they are located. Wall lighting fixtures can be UL listed for interior use only, or Dry location, they can UL listed for Damp locations, meaning they can be in indirect contact with water, or they can be UL listed for Wet location, meaning they can be in direct contact with water. Some examples of Wet location wall lights would be for lighting up a steam room or shower in a home, another place may be in a marine environment, on a pier, or a boat slip. If you need wall lights for a patio on a residential home that is covered, they may only need to be damp location listed since they won't be in direct contact with water. On the interior of a home or commercial building you can use any of the three mentioned above. Wall sconces are frequently used in halls in both homes and businesses to provide light to both the wall and the walking areas. Decorative outdoor wall lights are used on garages to provide beauty and functionality. RLM type wall lights are used mainly on commercial type buildings to highlight signage or entrance ways into buildings, but are also gaining in popularity on residential homes. Wall lighting is fantastic way to provide much needed light to a space not accessible any other way. The design possibilities are endless and include traditional, contemporary, modern and rustic. LED and energy efficient models are also abundant and provide tremendous amounts of light for a fraction of traditional running costs. Make sure you contact your lighting specialist to choose the correct wall lighting fixtures for your needs.
