For the plants you need a full spectrum grow light. Anything sold as a plant grow light should work. Full spectrum includes some UV. Depending on the tank you end up getting, you might get a fixture designed for that tank, or get, say, a hanging lamp.

However, you might also want a low level UVB bulb, like one of those sold for "Tropical" terrariums.

As far as not heating up fluorescent or LED bulbs would be the best option.
