The present invention provides a handheld portable, efficient instrument for curing light-curable compounds. The instrument comprises a housing, a light emitted structure supported in the housing, and a reflector configured to interface with the light emitting structure such that light emitted is captured and directed by the reflector onto a light-curable compound. The reflector maximizes the amount of light transferred and contacting the light-curable compound thereby reducing the instrument=s power requirements and improving efficiency. The light emitting structure comprises state of the art, energy efficient, light generating dies. The curing light instrument may also have a self-contained power supply lending portability and convenient of use.
