Can you give some details of your enclosure? Oz Brights (mercury vapour) are great for dragons and monitors as they supply heaps of UV and also heat. The only down side is they cannot be run off a thermostat. You can stick them on a timer though and if your enclosure is big enough you may not even have to do this, all depends on the size, ventilation etc etc.
You can use 10% style UV tubes such as outback max or compact fluoros such as compact max, it all comes down to size of enclosure. These can both be used with timers to stimulate a photoperiod and have a oz black or oz white ceramic for a heat source, or an infrared if you prefer a globe. These can be put onto a dimmer stat like a microclimate B1 to control your temps. Although the 10% UV tubes provide a lot of UV, you should allow your beardies to get fairly close as they will get mcuh better UV the closer they are.
Natural daylight is unbeatable, but you need to have them time to ensure that they get an hour a day and also that they have shade and water in case they get too hot, personally, I just give them articial UV as they do just as well on it provided they can get near enough to the UV source.
