yeah the flourescent is your uvb and because that doesnt really give off too much heat the you have to use something else for a basking.
there are some basking/uvb bulbs in one.. but the only ones ive seen have been close to $75 in the pet stores.
all that really matters is the temperature at the basking area. so if a household bulb does the job.. then use it.. if you cant get it close enough to make any difference in the air temperature.. then you may need to use a real 'heat bulb' from the pet store.
i used to clamp a regular 60 watt bulb onto the tank and it worked just fine, but recently ive had to move the bulb a pretty good distance away from where it was, and i had to switch to a 'basking spot' bulb which works really well, and it has some uva in it too.
