This salt lamp is made from natural salt crystals from the Himalayan mountains. Once lit, the lamp will emit a calming amber color, heating the salt with the included 15 W LED bulb, releasing negative ions into the air, and creating an effect similar to ionizing and purifying the surrounding air. Due to the natural variation in crystal salt, weight, size, color, and shape may vary. The lamp can be on with a dimmer touch control. To care for the orange lamp, we gently recommend wiping it with a paper towel if the salt is damp.
