A nonimaging light assembly for flashlights, including a light source and a lens symmetrical about an optical axis for receiving light from the light source and producing therefrom a light beam having concentrated and divergent components resulting in a high intensity core beam surrounded by a smoothly transitioning lower intensity surround beam. In a preferred embodiment utilizing a light emitting diode as the light source, the combined light beam produced by the light assembly has a substantially circular cross section.
