We present results from deep Spitzer IRAC and MIPS observations of a sample of 23 cores selected from the c2d Legacy Project. Candidate Very Low-Luminosity Objects (VeLLOs) were detected in some of these cores with the c2d observations, while others appear to be starless. The deeper observations were undertaken in order to confirm or reject the VeLLO nature of the candidates, and to search for fainter, deeply embedded objects hidden within the starless cores.We identified and characterized the Young Stellar Objects in these star-forming regions and determined their individual fluxes and Spectral Energy Distributions (SEDs). We also determined their accurate luminosities by modeling the SEDs and compared these values to models of protostellar evolution to examine whether they are are consistent with predictions of mass, mass accretion and age.
