  We present the results of numerical simulations of stationary, spherically
outflowing, electron-positron pair winds, with total luminosities in the range
10^{34}--10^{42} ergs/s. In the concrete example described here, the wind
injection source is a hot, bare, strange star, predicted to be a powerful
source of pairs created by the Coulomb barrier at the quark surface. We find
that photons dominate in the emerging emission, and the emerging photon
spectrum is rather hard and differs substantially from the thermal spectrum
expected from a neutron star with the same luminosity. This might help
distinguish the putative bare strange stars from neutron stars.
