why does the chlorine molecule break homolytically not the c-h bond in an alkane?

the Cl-Cl bond is weaker than the C-H bond, reaction with chlorine is normally done in the dark and started with a flash of light, the photons in the light have enough to break the Cl Cl bond but not the C-H. ?

C-H bond enthalpy is nearly double that of the Cl-Cl bond enthalpy (413 vs 243 kJmol^-1). Hence UV light has enough energy to allow for homolytic fission of the Cl-Cl bond but not the C-H bond.
