A light beam hardening apparatus is provided for hardening a material, such as dental material, exposed to light emitted by the light beam hardening apparatus. The light beam hardening apparatus includes a semi-conductor light emitting source operable to emit light in the visible light spectral range of a light strength of at least 200mW/cm2, a base receptacle for supporting the semi-conductor light emitting source, and a heat conducting connection for conducting heat from the semi- conductor light emitting source to the base receptacle. The semi- conductor light emitting source includes a plurality of light emitting chips or light emitting diodes (LED). The base receptacle includes a plurality of cradles each for supporting therein a respective one of the light emitting chips.
