You can't change out the bulbs -- if the light fixture runs a certain watt T5 bulb, you are stuck with it.
At 2 watts per gallon, you have barely enough light even to keep the most low light corals. In fact, anemones need anywhere from 6 to 10 watts per gallon.
You are better off buying new lights if you want to keep corals and anemones. If you buy T5s, go for a light that has individual reflectors -- as the individual reflectors can increase the output from the light by up to 300%.
