Instead of looking at the wattage per light you could look at your entire set up.
a 10 gallon tank usually has 2 15WK Bulbs (I have 2 7W GE bulbs that outputs 40W)
a 28" tank (29 gallon...30 gallon) you have a 24" blub with 20W GE outputs about...115W I think...
so both of my lights output brighter than listed wattage.
Its all about finding the right bulb in the right spectrum for you hood or light set up. If you don't have a set up then you can start from scratch.
I'd get the new bulbs that are rated low wattage so they are safer for most hoods and light fixtures but still output 4x more light than the normal bulbs.
With the technology we have today you have to look at the Kelvin rating, 6500k (Kelvin Rating AKA Color Temp. Mainly blue and red light). You want to look at the Lumens (Light Output). Wattage can throw you off with the new stuff that is out. I think that will be your best guide.
