Salt lamp

Salt lamp

A salt lamp is a lamp carved from natural salt crystal, often colored, with an incandescent bulb or a candle inside. The lamps give an attractive glow and are suitable for use as nightlights or for ambient mood lighting. Himalayan salt crystals are prized for this purpose, as it is believed by lamp vendors that salt from the foothills of the Himalayas has greater clarity or purity. The largest producers of this product are located near to the source in Pakistan, with Poland and Iran also offering variations.

The lamps are often sold with claims of their health-promoting properties, such as the ability to release ions that purify the air, but these claims have not been substantiated and are generally regarded as pseudoscience.
