Intensity / Range of XT12GT and XT12S

When comparing the Klarus XT12GT and the XT12S, I am wondering that peak intensity and maximum range do not correspond to each other.

The Klarus XT12S is advertised with a peak intensity of 40,401cd and 402m range.

The Klarus XT12GT is advertised with a peak intensity of 90,902cd - i.e. more than twice as the XT12S - but only 603m of maximum range.

Shouldn‘t the XT12GT have more than 800m of range as candela and meters should scale linear in the same way?

Any help to understand those specs would be greatly appreciated.
