Depending on the T5 fixture, it's probably your better option. Despite being lower wattage, the T5 are more efficient when it comes to putting light in the water. PC bulbs have re-strike issues and don't work with reflectors as well as T5s. This is mostly due to their shape. If the T5 light has individual reflectors around each bulb then there is no question that it's better. T5s also have better quality bulb availability, so that's another advantage.
