Keep in mind what you want your flashlight to do.

It seems many of those selecting flashlights want maximum "throw" - the ability to shine light on a distant object, but that characteristic does have a drawback.

I have two lights that I like and are well respected at http://www.flashlightreviews.com. I'm not pushing these specific models - there are many out there that are as nice or nicer. I'm just making a point of buying a light that matches your usage:

Streamlight ProPolyer Luxeon 4AA
This is a nice light that throws a small very bright spot of light an amazing distance (for a plastic cased LED light), BUT when I try to use this flashlight to light my way while walking at night (down paths, avoiding dog droppings in back yard, etc...) the bright beam is simply too narrow to help. Think of a spot light. From what I read many of the metal cased LED lights are even brighter!

Underwater Kinetics 4AA eLED
This light throws a softer more uniform 'flood' pattern of light. It does an exceptional job of lighting a broader area in front of my walking path. Think of a tight flood light.

If I'm trying to see something off in the distance I certainly want a long-throw light like the Streamlight (and many other metal LED lights that cost more), BUT if I'm trying to light up a closer area, such as while walking or doing up-close tasks (which is 90% of my flashlight use), I will grab the UK 4AA eLED with its softer flood lighting every time (or use a headlamp - Princeton Tech EOS for me).
