A flashlight includes a lamp support, an electric light-generating mechanism in the lamp support, a covering member around the lamp support, a barrel body joined on the covering member, and an adjustment member; the adjustment member is threadedly joined in the lamp support, and can be turned to adjust a position of a focal point of light emitted from a light source of the light-generating mechanism; front and rear heat-conducting components are positioned on front and rear ends of the light-generating mechanism respectively, and they contact the lamp support and the barrel body respectively; heat produced from functioning of the light-generating mechanism will be conducted away from the front heat-conducting component to the lamp support and from the rear heat-conducting component to the barrel body, and the light source is prevented from being damaged by the heat produced from it continuing shining for an extended length of time.
