Lighting calculations

[daddy01]

Hi,
I'm new to reefing and saltwater in general. My question is in realtion to the lighting for soft corals and mushrooms in general.
Everything I've read either specifies X watts per gallon, now I have currently a aqualight rated at 65Watt Daylight and 65Watt Actnic, totaling 130Watts, so at 5Watts per gallon that supposrts a 25Gal aquarium right?
does the type of bulb whether Actnic Blue or Daylight white come into play?
Am I making myself clear?
Jim
