So, you can use all sorts of lights to keep a plant alive.....this does not mean that it is going to grow strong or be attractive.
Many keepers will put lights over their enclosures and get what they describe as explosive growth. It's a catch 22. The plant may grow vertically very fast....but this is because the light isn't strong enough and it is actually putting all of it's energy into getting closer to the light source.
It all comes down to how close the plant is to the light source. In chameleon enclosures, we always try to provide vertical area for the chameleon. In saying this,. you will need a light that can penetrate deep enough into the cage to give the beneficial light needed for your plants.
I have played around with many light sources to see their affect on plant growth. Kind of a hobby of mine. You have many options. I have used the CFL like
@brownie64 showed above. I have had really nice results with them when cages have been filled with pothos or something of the like.
I like to run T5's over the top of my enclosures. Not only is the light more effective, I also like the looks of a flat fixture v a dome light. Aesthetics yes, but I have many enclosures and having that many domes would be quite ugly in my opinion.
I have also been playing with the jungle dawn lights. They make a LED that I have fallen in love with. It comes in three different size options. I have had amazing success with it. When really wanting a cage to look good, you have to use lights that not only induce growth, but they also need to be able to keep compact plants compact. This requires the right levels. Theses lights have done great with this. There is also a Jungle Dawn Mega Spot LED bulb that is fan cooled and it is AMAZING. The light resembles sunshine breaking through a canopy. It is awesome. Great plant growth and will grow anything I have put under it.......and the plants grow correctly.
There is nothing worse than looking at an enclosure that has been filled with great plants and a month later they are all leggy and ugly. The only way to avoid this is with good light.
With all that said, I would run with T5's or something from the Jungle Dawn line of products.
