I love Ott lights! I have had a floor model for over 12 yrs and have never replaced the bulb. I have 2 models that attach to both my sewing machine table and cutting board. I like how they don't take up needed room. I did buy one of the fancier models--silver--for reading and handwork in my bedroom, but I don't think they put out the same amount of light as the original styles--guess I like the light bulb that is in "bar form" as I call it. The light bulbs that look like the shape of a normal light bulb aren't as bright in my opinion. I have purchased lights at Big Lots that were off brands--they have worked fine and are definitely cheaper. One thing to keep in mind---some of the other lights get quite warm and before you know it you feel like you are lying under the sun at the beach. Never any problems like that with the OTT!
