Effective lighting depth

At what depth does T5 lighting loose its optimal power? i have two 48 watt t5 fixtures above a 29gal (18in tall) and was hoping someone knows how deep those lights are good for so when i decide to upgrade to a 45 tall(24in tall) i will know if i need something more powerfull like halide
thanks in advance
