  In this paper we consider generalized uncertainty principle (GUP) effects in
higher dimensional black hole spacetimes via a nonlocal gravity approach. We
study three possible modifications of momentum space measure emerging from GUP,
including the original Kempf-Mangano-Mann (KMM) proposal. By following the KMM
model we derive a family of black hole spacetimes. The case of five spacetime
dimensions is a special one. We found an exact black hole solution with a
Barriola-Vilenkin monopole at the origin. This object turns out to be the end
point of the black hole evaporation. Interestingly for smaller masses, we found
a "naked monopole" rather than a generic naked singularity. We also show that
the Carr-Lake-Casadio-Scardigli proposal leads to mild modifications of
spacetime metrics with respect to the Schwarzschild-Tangherlini solution.
Finally, by demanding the same degree of convergence in the ultraviolet regime
for any spacetime dimension, we derive a family of black hole solutions that
fulfill the gravity self-completeness paradigm. The evaporation of such black
holes is characterized by a fluctuating luminosity, which we dub a lighthouse
effect.
