the amount of watts has very little to do with output for the various types of aquarium lighting available. T5HO with good individual reflectors at the same wattage as PC will have two or more times as much output. It has been tested and proven. 2 x 24 T5HO will most likely have more output then a 96 watt pc, especially at depth. Don't let wattage fool you, it has very little to do with output unless the technologies are equally efficient.
