Color changing pure Himalayan Salt lamp w/color changing LED bulb. Each crystal is unique! Himalayan salt is known to be a natural ionizer while cleansing the air. The lamp's LED bulb heats the salt crystal at a very low temperature which allows the salt crystal to attract moisture within the area. The moisture evaporates quickly and clean air circulates in your area. Included with this lamp is an LED color changing bulb that should give you several hundred hours of use. USB cord included approx 5"diameter. Individuals sensitive to light or have concerns of photosensitivity should be aware of bulb color changing. *Due to this being hand carved, along with various screen resolutions, brightness, and colors may vary slightly from photos. Also please keep in mind due to various locations of mining, and differences of each stone will not be identical. DISCLAIMER: We feel that crystals can complement other therapies and support energetic well being. Crystals should not be used as a replacement for medical treatment.
