Yes the wattage is correct but that type of lighting isn't powerful enough to reach even the bottom of that small of a tank with near the amount of strength to sustain anything but super-low-light corals long-term because a power compact flourescent of roughly that size is still much more powerful which is why people don't just stack tons of regular flourescent lighting in thier large reefs.
PS... second that lighting rule needs to go when talking about reefs.
PPS... I'm too lazy to care about punctuation now.
