I purchased this salt lamp based on possible health benefits, that it would clean the air in an environment. Well, I haven't seen any benefits to that claim. I keep the lamp in my office. It looks like a huge pink and white salt crystal. I could not get over how heavy it is. It weighs in at 5 pounds. Everyone comments on it and wants to touch it. When you have the light cut on, it does provide a calming effect. After you have the light on for a while, it also it a pretty good hand warmer. I like having a piece of nature on my desk. I would have thought that the hot light bulb, on the inside, would make the salt melt a little bit. The lamp is the same as it was a year ago. The bulb is easy to replace and it is the size of a large Christmas tree bulb. They are sold in most hardware stores. It sits very stable on any flat service. It is more of a decoration and conversation piece. Its fun.
