Can anyone recommend the appropriate wattage I can use in each light for a tent setup mentioned above?
In general - as much as you can get... However, less light is ok as long as the following:
1) You have a tripod
2) You setup to not have movement (timer helps here)
3) Use all the same type of lights (and no flash)
4) You take the time to make sure to try and figure out the color temperature of the lights (or get ones where it is stated)
5) If you go with florescent, make sure to let them warm up completely so that they get to a consistent color and brightness each time you shoot.
All of those things will help you in post-processing (or reduce how much post processing you have to do).
What kind of camera are you shooting with?
