A long range, high intensity spotlight for human incapacitation and control that uses an incoherent collimated constant light source of sufficient intensity and focus to cause temporary incapacitation of a person for a period of time when illuminated by the beam without causing permanent physical harm. The high intensity spotlight comprises a head portion at one end having a window opening and a handle portion connected to the head portion and containing electronic circuitry and thermal air management for controlling operating temperature of the lamp. A paraboloid reflector is mounted in the head portion to face the window opening, and a high intensity electric arc Xenon lamp is adjustably mounted within the reflector so that the electrode gap is located as close as possible to the focus of the reflector. An adjustable mounting base allows the position of the reflector to be adjusted until the optimum focus is reached. A properly positioned cathode wire feed optimizes the lamp performance.
