I really like this lamp. It's so different and unique. No 2 salt lamps will be the same. It is so pretty when lit up. Even when it isn't lit up it is still pretty and a great conversation piece. It is powered by a 6 foot electrical cord. You turn it on and off my turning the dial that is on the cord. You can also control the brightness of it by turning the dial. The rock is authentic pink salt sourced straight from the Himalayan mountains. The lamp comes two 15 watt light bulbs. The base is made out of real wood. Another big plus about this lamp is that the company offers a lifetime warranty!
