Exact bolometric light curves of supernova shock breakouts are derived based on the universal, non-relativistic, planar breakout solutions, assuming spherical symmetry, constant Thomson scattering opacity, {kappa}, and angular intensity corresponding to the steady-state planar limit. These approximations are accurate for progenitors with a scale height much smaller than the radius. The light curves are insensitive to the density profile and are determined by the progenitor radius R, and the breakout velocity and density, v{sub 0} and {rho}{sub 0}, respectively, and {kappa}. The total breakout energy, E{sub BO}, and the maximal ejecta velocity, v{sub max}, are shown to be E{sub BO} = 8.0{pi}R{sup 2}{kappa}{sup -1} cv{sub 0} and v{sub max} = 2.0v{sub 0}, respectively, to an accuracy of about 10%. The calculated light curves are valid up to the time of transition to spherical expansion, t{sub sph} Almost-Equal-To R/4v{sub 0}. Approximate analytic expressions for the light curves are provided for breakouts in which the shock crossing time at breakout, t{sub 0} = c/{kappa}{rho}{sub 0} v{sup 2}{sub 0}, is <
