Thats a rather strange question, unless I just dont get it. Are you talking about the term compact fluorescent, in which yes, they are called cfl's, http://en.wikipedia.org/wiki/Compact_fluorescent_lamp
they arent all spiral, some are just single, double or triple bent tubes for example, but they are all designed to be relatively compact compared to there linear tube (2 foot, 3 foot, 4 foot, 5 foot, etc.) fluorescent bulbs. I;ve got a 40-some watt one in my garage and its still only about the size of a 'large' coffee mug.
