Salt crystals lamps are natural negative ions generators.
Salt is naturally hygroscopic which means it naturally attracts moisture.
The interaction of humid air with the surface of a salt crystal releases negative ions.
When a salt crystal is heated slightly, it generates negative ions. In order to facilitate this, a small light bulb (usually 7 to 40 watts) or tea light is placed inside a salt crystal.
Therefore, it is important to remember that any salt crystal lamps or tea light holders under normal conditions will only generate negative ions when it is warmed by the internal light bulb or tea light. T
he size of the salt crystal lamp and the conditions of the surrounding area, will ultimately determine the radiant effect of a negative ion discharge.
All lamps come complete with light bulb and lead.
