Just to be a bit different I have an Exo Terra compact hood that allows for 3 CFLs to be screwed in. I alternate between 2 plant lights and 1 UVB to 2 UVBs and 1 plant. I think this is sufficient and will get the job done; however a good linear T5 HO dual tube set up would be much better and I will be upgrading eventually.
Ultimately you can save money by doing CFLs (because the fixtures are less expensive) and it will work but the linear tubes are a bit better for coverage and when you're playing bulb musical chairs like I am the linear tubes are much easier.
