  We study the scattering modes of light in a three-dimensional disordered
medium, in the scalar approximation and above the critical density for Anderson
localization. Localized modes represent a minority of the total number of
modes, even well above the threshold density, whereas spatially extended
subradiant modes predominate. For specific energy ranges however, almost all
modes are localized, yet adjusting accordingly the probe frequency does not
allow to address these only in the regime accessible numerically. Finally,
their lifetime is observed to be dominated by finite-size effects, and more
specifically by the ratio of the localization length to their distance to the
system boundaries.
