Salt Lamps come with 12 Volt cord and a 12 watt bulb
Salt lamps when on have many advantages over normal ionizers. They improve the general atmosphere of any room. The Salt lamp binds the negative ions with excess positive ions. When it becomes warm, it absorbs moisture and the crystal will be damp on the surface. This builds up the ion field. Placing a Salt lamp next to a television or computer reduces the electromagnetic field that these produce. Over exposure results in nervousness, insomnia, lack of concentration and accumulation of more free radicals in the body, known to be a cause of cancer.
