I've looked at those "bearded dragon kits" and most of that stuff isn't really good for beardies. They have the calci sand which has been a cause of death to beardies. the coil bulbs also have been known to cause eye problems with them which directly causes lack of eating because they can't open their eyes because the pkc (eye problems). You aren't the first one to waste money on those things and, unfortunately, you won't be the last. They usually have a stick on thermometer which is o.k. but you can't base your basking temps on them because all it gives you is the ambient tank temps.
I suggest you use the reptisun 10 tube. It's a fluorescent tube and it is the best fluorescent uvb you can buy. The best place to purchase them that I know of is petmountain.com or lllreptile.com. I suggest you go to Walmart or Lowes to get an accurite digital thermometer with probe. The ones we have give you two temps and a humidity reading. I put the thermometer on the cool side, right next to their hide box that they sleep in and the probe goes on their basking spot. The only problem with that is if your beardie decided to sit on the probe, the temp suddenly goes from 100+ to about10 or 20 degrees cooler as the probe is measuring the temp of your beardies' belly. You can also get a temp gun. I haven't been able to afford one yet but that is great, all you have to do is point it at the back of your beardie and you get an instant reading of the temp where your beardie is.
I hope this helps some. It's late here and I'm rather sleepy.
