What are the Brightest X-ray Point Sources in Galaxies?. For reviews see astro-ph/0307077 Brightest: Lx(2-10keV) >10^38 ergs s^-1 Non-nuclear Stellar mass BHs and NSs LMXBs <3M_sun, transient/persistent HMXBs >3M_sun BH fallback disk (Li, 2003 astro - ph/0309321)

The integrated luminosity (2-10keV) is 2-3*10^39 erg s^-1, to which LMXBs contribute 90%. 55 high mass and 135 low mass binaries brighter than 2*10^35 erg s^-1. LMXBs a cutoff at 2.7*10^38 ergs s^-1 HMXBs
