ASP Triads provide incredible brightness in a small format. The smart chip technology of Triad lights automatically recognizes battery strength and adjusts the driver to compensate for any increase or decrease in voltage. The lights maintain a consistently brilliant beam. Their three position rotary collar locks the light, provides intermittent illumination or allows constant-on activation. The Lithium power cells have a ten year shelf life. The self-contained Parabolic Reflector Assembly is metalized and gasket sealed. The independent focusing elements create a room illuminating halo as well as a penetrating central beam of incredible brightness.
