There for sure is an objective way to measure the amount of energy a light gives off. Its called the "par" of a light and it varies depending on depth of water in your tank.
But, this is pretty useless becuase I can't really think of companys that rate there lights like that.
I think what you might be looking for is t-5's. These are florecent lights that give off enought juice to keep any type of corals. Now, what kind of t-5's you need I have no idea because I have metal halides.
