How tall is the tank ?
Will the basking and the UVB10 lights be mounted under or ontop the lid ?
is the lid a solid timber top or a mesh screen ? mesh is BAD.
I suggest you invest some money in a couple of digital thermometers (with the probe on the end of long cable) ie
http://www.vetnpetdirect.com.au/serenity-LED-digital-aquarium-thermometer?gclid=CJehyLHH89ECFYKVvAod0_0CwA&gdfms=C632FD23CCD3459793177D4193E82F6B&gdffi=10600f223f474e1c9ae213f32fb3a662 , I use 3 per tank for my lizards, you can buy these very cheaply via Ebay ($3 EACH), and they are quite accurate enough for your needs (within 1oC) , very good for getting air temperatures and zone temperatures and surface temperatures when then probe is taped tightly to the surface of interest,
and an noncontact (laser) thermometer gun like
http://www.avidreptilesupplies.com.au/shop/gauges/infrared-temperature-gun/ , I use one with has a tight spot (18:1 ==> I measuring a 1cm diameter spot at 18cm distance), the larger the ratio ,the smaller the spot at a given distance, these will only give surface temperatures, but you can measure without having to touch the surface with a probe. I bought mine via Ebay.
try LLL Reptile and other the other online reptile gear stores (Google is your friend) , you'll likely get your gear cheaper than from the local pet shops too.
If your hot / basking spot is at about 40oC (100F) it's fine, if it's cooler than 38oC you need either :
>>> more wattage (good MVB is an excellent option = UVA + UVB + heat + bright white/yellowish light all in one unit, MVBs can not be dimmed and are best operated off or on ONLY
or
>>> more wattage , a 80W or 100W par38 Philips clear COLORLESS incandescent spotty is a good option , lots of bright white/yellowish light and heat , no UV
or
>>> move the globe closer to the basking spot (make sure lizard can't reach or leap onto it)
or
>>> provide a basking perch that the lizard can climb to find it's preferred basking temperature , a branch that's fallen off a tree can be great basking perch for a beardie (who a good climbers)
Make sure you have NO coloured globes, these are useless and of no benefit to a beardie and can effect their behaviour and feeding.
Make sure you have a good quality UVB source , rated at least 10% UVB. If you have a screen between the UV source and the lizard you will cut the UVA and UVB reaching the lizard by at least 25% (hence screens are bad).
