I needed a high watt 3-way bulb for a floor lamp in my dark office, as an alternative to bad florescent lighting overhead. It isn't easy to find 250 watt 3-way bulbs. Most are 50-100-150 watt, which wasn't as much light as I wanted. I went to three local stores in search of 250-watt bulbs, but had no luck. Finding and ordering the correct bulb from walmart.com took about five minutes. Sold in packages of two, they are very competitively priced.
