The optical and optical/near-infrared pseudobolometric light curves of 84 stripped-envelope supernovae (SNe) are constructed using a consistent method and a standard cosmology. The light curves are analysed to derive temporal characteristics and peak luminosity L_p, enabling the construction of a luminosity function. Subsequently, the mass of ^(56)Ni synthesised in the explosion, along with the ratio of ejecta mass to ejecta kinetic energy, are found. Analysis shows that host-galaxy extinction is an important factor in accurately determining luminosity values as it is significantly greater than Galactic extinction in most cases. It is found that broad-lined SNe Ic (SNe Ic-BL) and gamma-ray burst SNe are the most luminous subtypes with a combined median L_p, in erg s^(−1), of log(L_p) = 42.99 compared to 42.51 for SNe Ic, 42.50 for SNe Ib, and 42.36 for SNe IIb. It is also found that SNe Ic-BL synthesise approximately twice the amount of ^(56)Ni compared with SNe Ic, Ib, and IIb, with median M_(Ni) = 0.34, 0.16, 0.14, and 0.11 M_⊙, respectively. SNe Ic-BL, and to a lesser extent SNe Ic, typically rise from L_p/2 to L_p more quickly than SNe Ib/IIb; consequently, their light curves are not as broad.
