I like the T5's. I have a regular Exo terra 5.0 tropical light in my day gecko tank and the plants grow like crazy. It will warm the tank up a bit though so be sure it won't get too warm for your frog. It can also dry the top half of the tank, so I have to mist well twice a day.

You can also use a GE 6500K CFL bulb, which are much cheaper. If you can't find them locally, amazon sells them. I get mine at Home Depot. I have one over my retf tank. It works fine, but the plants seem to grow faster under the 5.0 bulb.

Of course, you can also get 6500K strip bulbs/fixtures.

All bulbs will need replaced once a year if they don't burn out by then.
