A 1.0 solar-mass star should not reach 2.0 L during its main sequence (it is moving into its subgiant phase at that point). Of course, there are stars that break the examples of Space and one of them is quite close. Mu Hercules is a 1.1 solar-mass star that is a G5IV with a L of 2.7 that is 7.8 Gyr. It is too bright for its age and its mass, especially given its metallicity, as a star at its mass and age should be 20% dimmer (a lower metallicity should have accelerated its fusion processes slightly, there is less junk in the way of the fuel, which would have increased its luminosity but shortened its life). Now Space gives workable approximations and averages, but it does not account for all of the stars, even one of the ones that humanity has used as a benchmark.
