Bolometers have proven to be good detectors for the search of neutrinolessdouble beta decay. By operating at cryogenic temperatures, they featureexcellent energy resolution and low background. The detection of the possiblelight emitted when particles interact in the bolometer is a promising method tolower the background of the experiments. The different amount of light emittedin beta/gamma and alpha interactions, whether due to scintillation or Cerenkovemission, allows to discriminate the two interaction types. Because of thecryogenic environment, light detectors are often bolometers. In this work wepresent a software algorithm to lower the energy threshold of bolometric lightdetectors coupled to luminescent bolometers. The application to data from Gelight detectors coupled to ZnMoO4 and TeO2 bolometers shows that the energythreshold can be lowered substantially, increasing the discrimination powerwhen the amount of emitted light is small.
