I've had Volt before and loved them. Just purchased copper walkway lights that apparently can't get wet from irrigation water. They were stained and garbage after one night being installed. Customer service wouldn't cover them. Only suggested I polish them and move them from where irrigation water would hit them. They come with stakes to put in the ground....dirt. What application in dirt wouldn't likely have some plant material that needs water? I couldn't find any escalation path for support and very disappointed with their ability to stand behind their product.
