Depends on how dark it is.
I took the LS2 and LS3 out to some friend's house in the country (nice dark). On a moonless night, I was able to project nice clear beams on the side of a barn 50 feet away. I could have gone farther, but I wasn't testing for that.
Then a Arizona dust storm kicked up an it got kind of thick. It was real fun to have a 30 foot light saber to play around with.
Under normal lighting (city lights, etc) both lights are suitable for near to medium field work.
Last weekend, we took the LS3 in the pool and used it for night treasure hunting. This was at another friends house. Very nice pool. Pebbletech, rock walls, waterplants, waterfalls, etc. Lots of knooks and crannies to hide an Arc-AAA several feet underwater and use the LS3 to find it. With goggles, moonless night and clean water, the LS3 lit up the pool from one side to the other. Even though the AAA (LE) was the same color as the rocks, the beam of the LS3 made it fairly easy to find.
