We use the statistics of strong gravitational lensing based on the CosmicLens All-Sky Survey (CLASS) data to constrain cosmological parameters in aspatially-flat, inverse power-law potential energy density, scalar-field darkenergy cosmological model. The lensing-based constraints are consistent with,but weaker than, those derived from Type Ia supernova redshift-magnitude data,and mildly favor the Einstein cosmological constant limit of this dark energymodel.Comment: 10 pages, 1 figure; ApJL, in press; minor additions, new referenc
