  We present a revised measurement of the optical extragalactic background
light (EBL), based on the contribution of resolved galaxies to the integrated
galaxy light (IGL). The cosmic optical background radiation (COB), encodes the
light generated by star-formation, and provides a wealth of information about
the cosmic star formation history (CSFH). We combine wide and deep galaxy
number counts from the Galaxy And Mass Assembly survey (GAMA) and Deep
Extragalactic VIsible Legacy Survey (DEVILS), along with the Hubble Space
Telescope (HST) archive and other deep survey datasets, in 9 multi-wavelength
filters to measure the COB in the range from 0.35 micron to 2.2 micron. We
derive the luminosity density in each band independently and show good
agreement with recent and complementary estimates of the optical-EBL from very
high-energy (VHE) experiments. Our error analysis suggests that the IGL and
Gamma-ray measurements are now fully consistent to within ~10%, suggesting
little need for any additional source of diffuse light beyond the known galaxy
population. We use our revised IGL measurements to constrain the cosmic
star-formation history, and place amplitude constraints on a number of recent
estimates. As a consistency check, we can now demonstrate convincingly, that
the CSFH, stellar mass growth, and the optical-EBL provide a fully consistent
picture of galaxy evolution. We conclude that the peak of star-formation rate
lies in the range 0.066-0.076 Msol/yr/Mpc^3 at a lookback time of 9.1 to 10.9
Gyrs.
