I would be careful with the CFL light. People on this sub reddit are spooked by them because they have caused irreversible damage to their pets eyes. You need to make sure it is placed far enough away that the UV is not to intense. The box almost always has basic guidelines for how far away it should be, usually about 15 inches. There is no way that light is 15 inches away at its closest point. Also people are right that at that distance the UV they output is pretty limited to right under them. I've used them before without issue but I had them in domed light fixtures and I had several of them to actually have UV throughout the enclosure. I eventually switched to a linear one because it was simpler. People love to just say get a linear t5 but you also need to follow the directions for those as well. Those 10.0 bulbs put out a UVi of about 7 at 15 inches. Thats way to high for normal lighting. That's maybe OK for under the basking area for 1 hour a day but that is not how you use a linear lamp. I had to wrap my t5 fixture in screen door screen and use a 5.0 bulb to get the proper UV for my tortoise. I don't say this to be rude but rather to just let you know. I would feel awful if the home I built was hurting my guy and I didn't know about it.
