Each Wholesale Salt Lamp comes complete with light fitting, bulb & plug. Rather then sell them by size we sell them by approximate weight. Items are marked with sizes to give a rough idea of size only, each lamp is completely unique. Please note: Due to the hygroscopic properties of salt Himalayan salt lamps and candle holders 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 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. PLEASE NOTE: USA Retailer contact us for this item BEFORE the purchase so we can swap the cable with a USA PLUG
