This Himalayan Salt Lamp by #Denshine is fabulous. I placed it outside in the sun all day to ionize the salt rocks so that when I turn on the lamp it will cleanse the air. I also love the fact that unlike most of my other salt lamps, this one has a dimmer switch so i can turn it down or make it brighter at will. It's a perfect night light too. At only $22.99 thus is a real bargain.
