bigtwin,
THROW is the distance that is farthest penetrated by the light beam. SPREAD is the width of the illumination. As you know, there will be a hotspot, and a halo in the beam. The reach of the halo is shallow and the throw of the hotspot is the normally quoted maximum distance. I said the throw is 400-500 meters and it is. In fact that may be conservative.
A pencil type laser, run on only 1 AAA battery can give a throw of light of many miles. There is now a problem for airline pilots that report lasers blinding them on certain flight paths, where kids are pointing their cheap laser lights skywards. It requires little power to have a long throw of light. To have a powerful and wide beam spread is different. I did say in my mini-review that the beam was narrow.
