i have a powerfull LED flashlight ( Aurora 2AA) that has a very tightly focused beam that will reach far. But it also makes it a lot less usefull for short range uses: review2 review3 review1

Fenix also makes good lights, but have much less concentraded beams. I would recommend a visit to:

to find a light that fits your need and budget.
