Recent studies suggest that globular clusters (GCs) may retain a substantialpopulation of stellar-mass black holes (BHs), in contrast to the long-heldbelief of a few to zero BHs. We model the population of BH low-mass X-raybinaries (BH-LMXBs), an ideal observable proxy for elusive single BHs, producedfrom a representative group of Milky Way GCs with variable BH populations. Wesimulate the formation of BH-binaries in GCs through exchange interactionsbetween binary and single stars in the company of tens to hundreds of BHs.Additionally, we consider the impact of the BH population on the rate ofcompact binaries undergoing gravitational wave driven mergers. Thecharacteristics of the BH-LMXB population and binary properties are sensitiveto the GCs structural parameters as well as its unobservable BH population. Wefind that GCs retaining $\sim 1000$ BHs produce a galactic population of $\sim150$ ejected BH-LMXBs whereas GCs retaining only $\sim20$ BHs produce zeroejected BH-LMXBs. Moreover, we explore the possibility that some of thepresently known BH-LMXBs might have originated in GCs and identify fivecandidate systems.
