Abstract We study localization properties of low-lying eigenfunctions for rapidly varying potentials V in bounded domains Filoche & Mayboroda introduced the landscape function and showed that the function u has remarkable properties: localized eigenfunctions prefer to localize in the local maxima of u. Arnold, David, Filoche, Jerison & Mayboroda showed that arises naturally as the potential in a related equation. Motivated by these questions, we introduce a one-parameter family of regularized potentials Vt that arise from convolving V with the radial kernel We prove that for eigenfunctions this regularization Vt is, in a precise sense, the canonical effective potential on small scales. The landscape function u respects the same type of regularization. This allows allows us to derive landscape-type functions out of solutions of the equation for a general right-hand side
