Integrated spectra in the range (3600-6800) A for a sampleof 17 blue concentrated Large Magellanic Cloud (LMC) clusters arepresented. Cluster reddening values are estimated using the available extinctionmaps, while cluster ages are derived from the template matchingand equivalent width (EW) methods. Combining the present sample withadditional ones obtained under similar conditions, it is found that clusterdeprojected distances from the LMC center are related to age in the sensethat inner clusters tend to be younger.
