Measuring Florescent light output

Does anyone know a rule of thumb for measuring light output? Basically, what wattage do I use for cattleya culture, and what should I use for phalaenopsis or paphiopedilum? I know that distance from the bulbs also matter, so how far should they be from the source. Any info or link to a good instruction page would be appreciated!
