I consider the 3 kinds of lighting—basking, UVB, plant lights—separately. There are a number of advantages to this, not the least of which is control over each separately.
A single linear T5HO UVB is fine.
For basking, I prefer (in order of preference):
- Household incandescent bulb (not LED)
- Incandescent flood light (not LED and not spot light)
- Halogen flood light (not spot light)
A
clamp light fixture works well for basking lights.
Basking lamps are best installed/mounted at an angle to produce a temperature gradient rather than a hot-spot.
For plant lights, I prefer LEDs, specifically for a 24 x 24 x 48 enclosure I like/recommend:

Coupons are usually available.
LEDs are generally more powerful, last 5X longer, don't contain mercury, and many (like above) are self-contained and don't require an additional fixture.
I try to set up lights like a Venn diagram to allow the cham to seek out/find the light it wants/needs. This isn't as important for plant lights except that plant lights are often the brightest in an enclosure and reptiles instinctively try to bask under the brightest source.
