The invention discloses a light-pollution-proof accurate light condensation flashlight. The light-pollution-proof accurate light condensation flashlight comprises a heat dissipation shell, a gas light-emitting tube and protection glass, wherein a partitioned brightness light path mechanism and a control circuit for controlling the gas light-emitting tube are arranged in the heat dissipation shell;the control circuit is mounted on a circuit board; the partitioned brightness light path mechanism is mounted at the front part of the gas light-emitting tube and is used for generating different partitioned illumination degrees. The light-pollution-proof accurate light condensation flashlight disclosed by the invention has the characteristics of accuracy in light supplementation, good heat dissipation, partitioned adjustment of brightness and area of output light spots and intelligence in controlling.
