I bought some cheap CFLs from Walmart and all four of them have these strange bulges on their spiral, close to the base. I thought this was a defect but the box they came in features bulbs with the same thing. Here is a photo of the box http://i.walmartimages.com/i/p/00/68/11/31/07/0068113107722_500X500.jpg
Do you notice the strange bulge on the first bulb? On the first coil from the base? Why is it like that?
Most other CFL that I've used do not have this.
