When the basking lamp is placed inside your setup, it could be dangerous. Frogs can jump and hit the lamp and burn themselves. There are some frogs that use a basking lamp for the heat, but make sure you use the right lamp and the right amount of height. If your setup is big enough your frogs can go to a cooler side of the setup. It all depends on what species you have.

In my honest opinion: I would use a heat mat and some special lamps for the plants.
