Most of the lamps that I sell are made-to-order. Ocassionally I will have some in stock to choose from. Lamp height and base width are important factors when deciding on a shape and size. The height that you want the lamp and how much space there is for it to sit are key. Putting a wide based lamp on a small side table might not work, but that same lamp on a larger table would be perfect.
Here are just a smaple of the styles and shapes that you can consider. All of my lamps have UL rated components and use 8"-9"-10" harps. They have high quality components in an antique brass finish.
