What's emmanelson has said is good advice, but no matter what the wattage and the distance, you'll need to take a thermometer and check the temperature of your basking spot.
150 watts is a pretty hot bulb, that's what I'm using in Napoleon's tank, and it's about a foot and a half from the basking spot and still heating it to about 93.
You'll probably have to play around with the distance to get it right. For adult turtles your water should be around 76 degrees, and the basking spot should usually be about 10 degrees above that, although my turtles like it warmer. If you start with the 'correct' temperature and your turtles start basking, then you're good, otherwise start inching it closer to the basking spot just a little each day, and eventually you'll find the sweet spot that they like.
