Nothing in a frog terrarium needs UV light. The plants (including moss) need bulbs that are usually labeled as "daylight" in the hardware store and walmart. Strictly speaking, plants will do best on light between about 5000k and 6700k in color - some bulbs will say this but anything that says daylight will do fine. You do not need specialist reptile bulbs. Frogs after all are not reptiles.

CFL bulbs are fine. Some is having you on.
