There is some truth to the watts per gallon rule, but it depends on other factors as well. How much lighting you need primarily depends on what type of corals you are planning to keep as each coral species has differing lighting requirements. It also depends on the type of lighting...i.e., PC lighting will not give you the same results as Metal Halide although you may have the same wattage of each. There are other factors such as tank depth, light spectrums, etc. You might want to try asking this question in the Reef Tank forum, as you will get more responses....
There is some good information in this thread...
