Thanks a lot! I will definetly buy 2 uvb, one for now and one backup (still have a headlamp backup) I will also make some more notes such as the weight.As mentioned, in MY OPINION she looks fine. Not sick, no mbd no nothing so no need to get hysteric. She will come out of brumation when she's ready and the temps rise again. Your initial question was about some dents but I don't see anything concerning, to be honest.
If you are looking into a new bulb, here in Europe (I'm from Germany) we use the ReptiZoo D3 Super Sun a lot, it's a good mvb for the price with really high uvb output.
These were things I overlooked so I'm glad you all shared your opinion on the matter.
