5.0 bulbs produce very little UV. Those are usually only for forrest tortoises that prefer dimmer lighting. The 10.0 is the way to go. Only a UV meter can tell you the correct mounting height, but it will probably be around 18 inches.Ok I already bought a new plastic hide (it's for a hamster but it should work). As for the UVB HO T5 I have some doubts, should it be 10.0 UVB or 5.0 UVB? The description says 10.0 is for desert reptiles so I'm guessing that's the right one, but it's also more rare to find...
I'm also looking for a carpenter to follow Yvonne's advices, thank you!!
