What mathematical limits apply to luminosity?  Is it bounded on one or
both ends of its range?  If so, I'd look into (linear functions of) the
gamma and beta families, respectively.  They can be fit using the method
of moments or by iterative MLE.

You can also look for simple transformations that eliminate the skew or
introduce upper and/or lower bounds.
