Hi,
Yes, beardies need both UV and a white basking lamp, and what you show there should be good as long as proper distances are maintained for both. I've found that regular 75W incandescent flood light bulbs are about right for basking spots. Higher than that & I've had trouble with bulb distance vs. temp at the basking spot (too high). Also, those basking bulbs are expensive & burn out way too fast IMO. You'll want to get a dimmer for your basking light and an IR temp gun, which can be gotten online or at a Home Depot, etc. This will allow you to more easily fine tune the temperature to "just right" for your beardie.
Regarding UV, the main consideration is to not have anything between the light & the dragon: no screens, no plastic covers over the bulb, and so on. Usually, you can cut small slits in the wire mesh top that comes with aquariums and mount your UV underneath it using zip ties or similar. As far as the appropriate distance, that will depend on the bulb. I'm not sure what the max. is for the one you showed, but I have it just out of reach of my beardie shining down on his basking log. In a 50 gal tank, I believe the T5 with reflector is strong enough to give adequate UV at the bottom of the tank, but more experienced posters may be able to weigh in on that. I hope its the case because that's how mine is set up!
