By using a Himalayan Crystal Salt Lamp you replace the negatively charged ions in the air which helps us to avoid the alleged physical and mental harm that the ‘electric smog’ creates. Each Salt Lamp comes complete with light fitting, bulb & plug; each lamp is completely unique. Please note: Due to the properties of salt lamps they absorb moisture from the air. If your lamp is 'sweating' or leaking water this is generally due to being switched off for extended periods, especially in humid conditions. To remedy, leave in strong sunlight for 4 to 5 hours and brush off any excess crystals. Or wipe gently with a dry cloth. If you don't use the Himalayan salt lamp for long periods of time (eg when on holidays), disconnect the cable and remove it from the lamp. In humid conditions, we recommend placing your lamp onto a small tray or dish in case they may pool water.
