We present integrated spectra in the optical range (≈ 3700− 7100 angstroms) for 27 concentrated star clusters (SCs) of the Large Magellanic Cloud (LMC). E(B − V ) colour excesses and ages of these SCs are determined from two different methods: (1) Measurement of equivalent widths in selected spectral windows. (2) Comparison of the integrated spectra with template spectra. The current sample of integrated spectra complements previous ones in an effort to gather a spectral library with several clusters per age bin.
