If we will base our answer on Hertzsprung diagram, we
will see that mass and luminosity are directly related, which means, long lived
stars begin their lives with more mass and a larger amount of hydrogen fuel,

main sequence lives. Giant stars and supergiant
stars have great masses, so, they have greater luminosities.
