USB Rock Salt lamp 11.5cm

This small desk top USB Salt Lamp plugs directly into your computer via the USB port.

Himalayan crystal salt lamps are said to create anions (negatively charged ions) in the air. Since pollution and the use of electrical equipment create potentially harmful positively charged ions (cations) in the air and cause air quality to deteriorate, using a salt lamp helps counter the cations. This natural ionisation helps avoid the physical and mental harm created by the ‘electric smog’ around us.
Usage
Salt lamps can be used either with electric bulbs or candles
depending on the model, both emitting a soft, golden
light that lends visual appeal to a room. Not only do they
look good, they also function as natural air cleansers. Heat
from the bulb or candle make the crystal salt emit negatively charged ions, which enter the air and neutralise the positively charged ions created by pollution and electrical appliances. The neutralised ions become heavy and fall to the ground.

These lamps are made of natural crystal salt from underground mines in the Himalayas. The crystal salt is millions of years old and has a high mineral content as well as special properties. The cleansing properties of these lamps are said to help combat illnesses like allergies and asthma. Other sources of anions are waterfalls and the sea; these produce up to 10,000 anions per cubic
metre compared to just 100 anions per cubic metre being produced in a city at rush hour time.
