We have analyzed the parallelism between the properties of galaxy clusters and early-type galaxies (ETGs) by looking at the similarity between their light profiles. We find that the equivalent luminosity profiles of all these systems in the V band, once normalized to the effective radius Re and shifted in surface brightness, can be fitted by the Sérsic law and superposed with a small scatter (≤0.3 mag). By grouping objects in different classes of luminosity, the average profile of each class…
