First, I am assuming that you might be on a little bit of a budget.
You will need two lights. The first will be for use "throwing" light a long distance. For this, an old-fashioned Mag light ($20 - Walmart) or similar would work just fine. You won't get a long battery life, but this is for occasional use only. Use this when trying to see something off in the distance (buildings 1/2 mile away, hills, landmarks, etc.)
Your second light should be an LED for run time. The attitude would be great on a budget, and relatively easy to find. The Opaltec Newbeam is a bulb replacement for a mini-mag. It is nicer, but more expensive. Choose whichever one strikes your fancy. This could be your general use light to be sure that you don't trot into a tree or trip over a stump.
Then, because you got two flashlights for under $40 (assuming that you chose the Attitude), take your savings and buy a GPS so that you don't get lost! I know quite a bit about those too
