Had two 500W torchiere lamps we like due to the indirect lighting for the TV room. Both had 3-way switches that were failing - only working on high setting. This dimmer was easy to install with some basic tools and a few wire nuts. Be sure to read all the comments from othersabout diameter of the lamp pole, as this item would not fit in a different model 300W lamp we have with a 1" pole diameter. We're much happier with the dimmer than the 3-way switch...can set the light level exactly where you want it.
