I love my table top Ott: I put it to the right of my sewing machine so I can see just in front of the presser foot. The swirly bulbs are fluorescent bulbs, not the full/daylight spectrum used in Ott and similar lamps. I try to pick fabrics for a project using the Ott as well as standard incandescent and fluorescent lamps so I know what I'll get when I am done. Many dyes react differently to the various types of lighting.
