Wurkkos ts28 vs sk40 medium mode

I'm looking to get my first flashlight, and I want something that's a thrower and relatively small. I'm trying to decide between these two, and the medium modes are quite different. The ts28 is 250 lumens and runs for about 13 hours, while the sk40 is 500 lumens and runs for about 5 hours. Would 250 lumens be enough for outdoor use, and what kind of range would it get? The ts28 is a bit smaller so I would prefer to get it. Thanks
