Time to replace bulbs, looking for opinions

I currently have a 75 gallon tank with an Aquatic Life T5 HO 54w light. It has the stock bulbs...1 10000k white, 2 420/460 nm actinics and a purple bulb. I'm not overly happy with how the corals look...they look ok just not as colorful as I'd likeso I'm looking for opinions on replacement bulbs...my current frags are torch, australian blastomussa, galaxea, zoa, duncan, discosoma mushrooms, kryptonite candy cane, and a toodstool. I also have a rbta...Thanks
