These Salt Lamps come with a power cord that has an ON/OFF/DIMMER switch, and are available as:
-A natural, large chunk of Himalayan Salt that has been hollowed out to accept a light bulb.
-A bowl carved out of Himalayan Salt that has been hollowed out to accept a light bulb and is filled with chunks of Himalayan Salt
A Himalayan Salt Lamp is mined salt that has been hollowed out to allow room for a light bulb. The light glows through the salt crystal, and the salt can range in color from a dark pink to a pale orange. The salt crystals are mined in the Himalayas, and make fascinating accent lights. Their main attraction, however, is that when the lamp is lit, it heats the salt which causes the crystal to release negative ions which have long been considered healthy. The air we breathe is electrically charged, which means it comprises of positive ions and negative ions. Negative Ions are naturally created by rain, wind, waterfalls, surf and sunlight. For example, the sea air, mountain air and the air around swiftly running water is high in negative ions. Indoor air, re-circulated air, and air around electronic equipment is very low in negative ions. Positive ions are created as a result of the use of computers, televisions, tobacco and radio transmitters. Many people who experience health issues around fluorescent lighting and computer monitors report feeling considerably less fatigue and headaches if the concentration of negative ions in the air is increased. Studies have shown that negative ions in the air bind with airborne pollutants, making them heavier so that they fall to the ground, and therefore are unavailable to be inhaled. Some modern air purifiers, such as ionic air cleaners, use this technique to provide cleaner indoor air for allergy sufferers. Some studies seem to indicate that an increase in negative ions in the air increases blood flow to the brain, which would have the effect of improved concentration. The salt lamp is an attractive alternative to the utilitarian look of an air purifier.
