Here are beamshots courtesy of DarkGear showing the different 5W beam patterns using reflectors from two Mags on the left, and a Brinkmann NexStar on the right. The SNII uses an HD, the SN uses an SE, and the NexStar (NN), of which the reflector is much smaller and shallower, with less curvature along its side taper, uses an SE:
Note how tight and clean the 5W HD (SNII) can be focused using a Mag reflector. That beam will throw across the small canyon behind my home, easily 200 yards or more.
