When we talk about lighting the outdoors, landscape lighting covers all your lighting needs. They light plant materials, pathways, walls, mailboxes, facades, water features almost anything outdoors you want to illuminate. Landscape lights are either a 120 volt system or a 12volt system. The 12 volt systems require a transformer which converts the house current or line voltage 120 volt to 12 volt. Low voltage lighting has advantages allowing the lighting fixtures to be smaller in size and a 12 volt system is safer around people and pets. As with all other electrical lights, landscape lighting can use LED technology which is more economical in its use.
