In this paper, we introduce good definitions of some weaker and stronger forms of L-fuzzy compactness in L-fuzzy topological spaces in Sostak's sense, where L is a fuzzy lattice. We define these concepts on arbitrary L-fuzzy sets, obtain various characterizations and study some of their proper-ties.
