I have an old Cabelas light that has the two Luxeon 3w leds in it. I decided to swap in Cree XR-E R2 (WG) emitters. Nice and easy and worked wonderful. Now I am wondering if there is a way I can get rid of the donut artifact in the beam? At 25 yards it has a dark spot dead center. Would an aspherical lens help focus the two into one? If I cant fix it im fine with it because it is a beater light but it would be nice to get a better focus with all the nice light it now produces. Thoughts?
