Actually, the last time I went to JoAnns, they had a new OttLite bulb. It is an actual lightbulb that replaces a 100 watt bulb. It looks like the CFLs that are already on the market, but have a more true light (less yellow cast). I bought one and it's great. They are not as cheap as the regular CFLs, but for sewing or craft room where you want true color, it's so much better. I will probably be buying a few more next time the OttLites are on sale there or I will look elsewhere like eBay.
I just looked on the JoAnn's website and they have different wattages for these CFL style bulbs (

However, as other people stated, all the tube like OttLite bulbs will only fit OttLite type lamps.
