We compare the observed symbiotic nebulae (SyN) luminosity function (SyNLF) in the [O iii ] λ5007 Å line to the planetary nebulae (PN) luminosity function (PNLF) and find that the intrinsic SyNLF (ISyNLF) of galactic SyNs has—within its uncertainty of 0.5–0.8 mag—very similar cutoff luminosity and general shape to those of the PNLF. The [O iii ]/(Hα+[N ii ]) line ratios of SyNs and PNs are shown to be also related. Possible implications of these results for the universality of the PNLF are briefly outlined.
