Putting the light inside does not necessarily mean that your dragon can get closer than 6", unless you give them some way to climb closer.
I've also noticed that our dragons are pretty good at regulating their UVB and heat. Unless you force your dragon to always be closer that 6" away from the UVB, they will choose what they are comfortable with. Sometimes our dragons will get as close as possible (about 6-8" away in our enclosures), especially on days where they've been outside of their vivs alot. Sometimes they will find a low shady spot.
I don't see in any photos you posted where the dragon could get too close to the UVB bulb. All of the enclosures shown give the dragon many options on how much UVB they are getting. None of them look remotely unsafe. I would think the last pic you posted has the light a little too far away, and does not give the dragon many options to get different levels of UVB if they choose.
It's also wise to place the basking light close to the UVB light. Since you are using a very bright white or clear light it will divert their gaze from the UVB, which can be harmful if they (or you) stare in to the UVB light.

all 3 pics, have places that the dragons can go to and are less than 6" from the light. One point that can be made here is how much effort and debate is going into why not to choose other bulbs, but no one is talking about the harm that the wrong distance can do to the dragons. Also, I have read in many places that we WANT the 50% of the UVB to be absorbed. Other brands even SUGGEST that we put them above the lid for THIS reason

1. How do you know it's less than 6"? I think you're wrong, just an opinion. My opinion is that every pic you posted the dragon cannot get any closer than aprox 6". The last pic you posted as 'safe', looks like around 12-18" away.....which is fine, but give no option to get closer.
2. As an owner you can do what you like. I choose to let my dragons regulate themselves. Very rarely do they choose to get very close to the UVB...when they do, they must need it. Choose for yourself.

Intense natural sunlight puts out about 400-450uW/cm² of UVB. In the wild bearded dragons will bask in this sunlight for 3-4 hours a day. They will seek shade when it's too much for them. At 6" a UVB tube will put out about 25-30% of that. Also, studies show that bearded dragons will seek more intense UVB when suffering from MVB, and when they start healing they will stay further away from UVB.
