MDF Thanks for the detailed reply. I'm certain something isn't right with my setup. I'm trying to figure it out. got a hot basking spot that covers whole torso. The question now is. at 160F is that the temp of the floor? or is that the temp of the monitor's skin. Because the monitor is about 2 inches thick so if I measure the floor at 160F then when he's on the bask spot he would be over 160F. So that's a question I keep wondering about. I'd like to keep this discussion open until I get this fixed. I'm not happy with how my guy is lately I think he'll die if I can't figure this out.
Hope infernelis is here to read this, and anyone who has good experience feel free to jump in and help. I am looking at your latest youtube vid and I can really see your savs are way more thin and active than mine has become lately. I noticed your lighting setup in the video below. Can you please describe the type of bulbs, wattage and distance they are to the gound and the temperature they are at when you use a temp gun on the floor of the spot? I've been using 3x50 watt to get a 140F+ but yesterday I am getting desparate and got a 160Watt MVB to replace one of the bulbs but turns out the basking temp of those MVBs are really low unless I move them down closer to the basking board. So that's kind of what I have now.
The reason why I got the MVB is because I wanted to make sure the monitor's whol body would be covered in the light when basking. But I have a feeling I'm doing this all wrong and I'm getting frustrated.
I noticed no one here uses MVBs so I'm gonna try to imitate what you got in your video. Please help with directing me to get that lighting setup like yours. Thanks in advance.
Update: With the MVB + 50 watt halogen I've got a basking spot that covers the whole body. However the temp varies within the spot. I've got the 50% of the spot more in the middle at 160-165, with smaller area of 170F, then the remaining 50% of the spot(the outter circle) of around 135-140F. The humidity is still good, I will need another meter as the last one broke again. But my glasses still gets foggy when I enter the cage but def need to get a new meter to be sure.
Also I read that the MVB manual says that the UVB emitted is no stronger than the mid day sun under the shade. So I'm guessing even though I'm putting the bulb quite low it should still be safe.
I'm not sure how infernelis manages to have his bulbs so high up and still achieve 140F+.
Hi, is this a Powersun MVB? It isn`t only the UVB irradiation that needs to be taken into account, it`s also the heat, exactly how far from the surface of the bulb to the closest surface of the animal is it?
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+

Hi this is the powersun 160Watt. To get a 160F surface temp on the floor, the bulb is 5.5 - 6 inches away from the floor, I measured it with tape measure plus a temp gun. The 50 watt right next to it is 2-3 inches higher to produce similar surface temp. So I'm wondering since the monitor's body is thick, would this mean the bulb is too close. It seem to enjoy basking under that temp for 20-30 mins in the morning, then after that it only uses it for short periods. Then it lays somewhere else most of the time or goes in it's burrow.
For my tegu I'm using the same setup(with just the MVB tho) since his halogen floods got shotted(bad wiring on my part) But the tegu is functioning real well under this same setting. The only difference in the 2 animals is that my tegu would dig a burrow himself, however the sav needed me to make a surface on the ground and he will dig to live under the wood, but he does not make tunnels. The soil/sand mix is the same for both animals. 70% soil and 30% sand...
I just got a humidimeter and it says 75% humidity in the middle of the cage, lower than I had expected. It used to be 80%+ even 90% sometimes. It could be due to my house haing the furnace on more now that it's winter...
Not sure what else info I can give. I measured him today he is 2 feet 8 inches. Roughly, since he won't stay still when I was measuring him, keeps thinking I'll give him food.
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...

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.

I can't take a vid now since he's hiding again, but let me find a recent one these few days.
Edit: unfortunately I don't have one. I've been recording the tegu mostly since he moves. The sav hasn't hardly been moving except if I open the door so no vids for now. Tomorrow I'll take a video of him.

This is the most efficient way to set up a basking site using halogen (flood) bulbs. No apologies for showing this pic previously, it`s quite hard to get the message through at times!
I need to use more bulbs because of my monitor`s size, you may only need 2 or 3....
Don`t ever stop asking questions, if you don`t quite understand something ask for a further explanation!
One of the reasons the low wattage halogens work well is that they can be positioned relatively close without causing burns (obviously you must check very carefully), they can also be dimmed making it easy to adjust the surface temp, but you might need to use 2 or 3 as I mentioned.

Actually his head popped up just now so I lured him out with a fish. I measured him too in the video. He is not 1 feet 8 inches as I previously measured, but more like 28 inches. You can see in the video he's not totally straight and it's about 24 inches so I think stretched out is 28 inches or something.....
As you can see he's not looking too great...
Video is being uploaded to youtube so I'll post it in a few minutes!
