T5 Lighting or PC?

[Jericho]

I currently have a PC lighting system with 2 96 watt lamps on my 40 gallon tank. The ballasts blew and the lights no longer run. A guy at the pet store recommended that I replace my lights with 36" 39 watt T5 lighting. I have an assortment of soft corals, fish, and a bubble anemone.

Would it be best to purchase a new power compact system or to get the T5 lighting? The T5's operate at much cooler temperature but I worry about the low wattage. If anybody has any direction on what would be best that would be appreciated!
