A light including a light source that generates light centered along an illumination axis; an aconical reflector having a reflector surface that is symmetrical about an illumination axis and is open at first and second ends, the aconical reflector mounted with the light source located within the opening at the first end; an aspherical optic mounted at the second end of the aconical reflector; and wherein, a first portion of the light from the light source directly enters the optic and is collimated by the optic to generate a high intensity light spot along the illumination axis and a second portion of the light from the light source reflects off the aconical reflector and enters the optic and emanates from the optic at angles with respect to the illumination axis to generate a low luminance halo about the illumination axis and separated from the high intensity light spot.
