Carved into a cube shape, this Salt Lamp is a natural air purifier. Place the lamp in rooms to allow the negative ions produced to counteract the harmful electromagnetic fields being emitted from electronics. The Cube Salt Lamps are made from 100% pure Himalayan salt that is hand mined in the Himalayan Mountains. Once lit, the lamp will emit a beautiful rose glow. While the salt warms, it will release negative ions into the air, creating an effect similar to an ionizer, purifying the surrounding air. It includes a 6 foot power cord, 25 watt light bulb, and a rotary dimmer switch. App. 4"x4"x7"
