This paper presents a definition of $L$-fuzzifying nets and the related $L$-fuzzifying generalized convergence spaces. The Moore-Smith convergence is established in $L$-fuzzifying topology. It is shown that the category of $L$-fuzzifying generalized convergence spaces is a cartesian-closed topological category which embeds the category of $L$-fuzzifying topological spaces as a reflective subcategory.
