I use 6500 daylight bulbs. I run 2 for each enclosure. I use these ones specifically and they come with the daylight bulb

Others use LED options. I like the jungle dawn light bars. I don't know too much about those though.
Whatever you choose your plants will need the additional lighting to support health and growth. Otherwise they slowly die off. Pothos are about the only ones that grow no matter what you do to them. But if you have grow lights they thrive.
I have seen some people overdo it with lighting. Like a ton of T5 and led's. You just don't want to overdo it. But the right lighting is not harmful at all for the cham.
Keep in mind additional lighting will make temps at the top rise a bit. So you have to take that into consideration.
