Not to nitpick, but the ReptiSun 10.0 Tube is the good one. ReptiGlo 10.0 is garbage. I noticed you only mentioned a "Repti 10.0"? Don't forget the Arcadia 12% tubes, those are really good as well.
Has it occurred to you that maybe "everybody on every site is saying the same thing!" because there are proven standards in Bearded Dragon lighting?
The important thing with Bearded Dragon UVB lighting is the not the
strength of the UVB, which is what you have been researching, but
wavelength of the UVB rays being given off by the bulb. UVB wavelengths are 280 to 320 nm (nanometers). The wavelengths that bearded dragons need in order to make Vitamin D3 are 290 to 305 nm. No Vitamin D3 = No calcium metabolism = Unhealthy dragon = Dull colors.
So it's true that some of those lights may be stronger, but unfortunately, if they're giving off the wrong UVB wavelengths they will not be helping the dragon at all.
