Uvb's expire in either 6 months or 1 year depending on the bulb-- what did you use for cleaning? I can post all kinds of info for you tomorrow on the dragon - if you want me to - it's going to be a lot so info over load let me knowThe heat lamp is fluckers and it’s not a coil. But the uvb we’re not sure we’ve had it a couple years. It totally is possible he came from the store sick as a past crested gecko from the same store came visibly sick from the start. But the bearded dragon has also always had a lot more energy and has been fine that we’ve known for 6 months. Between the gecko and the dragon we did deep clean everything in the cage.
