Cebu sun is even more light than the radions. Think about either a pair of 2 or 4 bulb 36" T5s or just some 60" T5s. This won't need much light.
With it being a FO, you can change the bulbs every other year or even when they burn out. There is no reason to change them every year. Some will argue that old bulbs create algae problems, but this is bunk... high nutrients create algae problems.
