First thing is to check if your Pacman is an albino variety. If so; sorry but can't use any plant type bulbs.
If a regular pigmented frog; then you can use any light that peaks at around 6,500K. Recommend using low light requirement plants so that you don't make the enclosure too bright. Since plant bulbs are either fluorescent or LEDs; you might have to use additional heat sources if required. Good luck!
