sav stay in burrow all day

[nepoez]

murrindindi, Honestly I didn't get the MVB for the purpose of UVB. I got it in a panic to try to get a bulb setup that would cover his whold body for the sake of basking purpose not so much UVB. UVB would just be a bonus. But right now I don't think UVB is his problem, and my prime suspect was basking site error, thus the MVB I bought. So he's been using that for 2 days now + a extra 50w halogen flood. I don't seen any improvements, dispite the high basking temps...

If this is a Powersun, there are reports that the amount of UVB is much less than the manufacturer claims (at least in the American bulbs and perhaps also Canadian)? You really need a Solar meter to check.
Edit: An MVB like the Powersun has a beam radius of around 75cm at a height of 30cm, in which case it would easily have covered the whole body.
Personally I would recommend using the T5 HO (high output) fluorescent tubes (UVB), then the halogen floods as basking lights.
Check out the 12% UVB tube rather than the 6%...
Arcadia T5 reptile lamps 6% D3+

It doesn`t matter whether you used the MVB for the UVB, heat or just illumination, it MUST be at LEAST 30cm from the face of the bulb to the closest surface of the monitor (which will normally mean it`s head), even slightly closer can cause very serious burns.
I`m not disagreeing with Mark (MDF) or anyone else just for the sake of it, but offering a surface temp of 160f will NOT necessarily cause the animal to lose weight or become more active throughout the day. It will only decrease the time it takes to get the core temp up to "activity level" by a very small amount, maybe a couple of minutes or so (obviously the actual speed will depend on the monitor`s mass).
Unless you can achieve that raised surface temp without also raising the ambient too much must also be taken into consideration (if it`s too warm they retreat), in which case they`ll cool down, become less active, defeating the purpose of raising it in the first place! This species is most active during the cooler wet season when ambient temps don`t usually get "extreme".
Other species DO encounter higher ambient and surface temps and use them very regularly, I`m not suggesting raising them is a bad thing in itself, but 140f is perfectly acceptable and should ensure the monitor can operate at it`s full potential, providing all the other parameters are met.

EDIT: Can you take a video of the monitor?

OK in this case I will need more help again. Currently for any of my bulbs to make the ground's surface temp to be 140F, it has to be only 5-10 inches away. e.g. 50 watt halogen needs to be 10 inches from the ground, or maybe less, to reach 140F on the floor. And the MVB needs to be 5 inches away form the ground to reach 140F on the ground.

If you say the light bulb must be 30cm from bulb to ANIMAL, then I can't possibliy achieve 140F on the floor surface. So I am really confused now what I should do. Please advice. Sorry I'm a person that needs great details when explaining what to do so please be patient.
