I have one that mounts on my sewing cabinet and has a swing arm over my machine that can be adjusted-it is wonderful! I also have a smaller on that just sits on the desk that allows me to do handwork. I would like to purchase one that is a floor model to use when I sit in an easy chair to watch TV and do handwork at the same time. The Ott-Lites give good light that is comfortable for eyes (aging eyes in my case). They are worth their cost. I have not had to replace any bulbs yet.
