Rare event physics like Direct Dark Matter and Neutrino-less Double Beta Decay detection strongly benefit of event-by-event discrimination capabilities. Composite Heat and Light bolometric detectors have shown excellent performance of environmental gamma's, beta's and alpha's tagging and rejection and therefore are widely used in such physics. The rejection capabilities mainly rely on the light detector performance. We present here tantalizing results obtained with ultra-pure germanium light sensors, assisted by Neganov-Luke effect, and showing a gain of the signal-to-noise ration of the order of four and a light detection threshold of about 20 eV.
