For FOWLR, your concern for light is really just such that the fish look good to you visually, as you don't have any photosynthetic creatures. As far as algae issues, those generally arise more from your nutrient exporting methods. If you keep them low, algae shouldn't go crazy. That's usually the case in any aquarium setup, really. That is a pretty cheap light as said above, but if it makes the tank look good to you, go for it.
