In a recent study of 84 LMC stellar clusters, we showed there is only a weak correlation between the CMD age and the age assigned by means of their integrated photometry alone (Asa'd & Hanson, 2011). We seek to determine if integrated spectra alone can provide better age estimations of unresolved clusters. To investigate this, we are obtaining integrated spectra for our sample of 84 LMC clusters with CMD ages, and will present preliminary results for 7 clusters observed with the 4m Blanco Telescope (Chile) in the visible. We derive information about the age and the extinction of these clusters using the equivalent width of the Balmer lines, comparing the clusters' spectra with template spectra of star clusters with known parameters, and comparing the spectra with computational models. We will continue to obtain integrated spectra for all 84 clusters from our original study to investigate if spectra can provide more accurate age estimates than integrated photometry.
