Integrated spectra in the range (3600-6800) A for a sample of 17 blue concentrated Large Magellanic Cloud (LMC) clusters are presented. Cluster reddening values are estimated using the available extinction maps, while cluster ages are derived from the template matching and equivalent width (EW) methods. Combining the present sample with additional ones obtained under similar conditions, it is found that cluster deprojected distances from the LMC center are related to age in the sense that inner clusters tend to be younger.
