Having light in an emergency or while camping is very important. While shopping at Lowe's, I recently saw the Task Force flashlight and picked up a couple. I've placed them in certain locations in my home in case of a power outage or for when I need to visit the attic. It requires 3 AAA batteries that come in the package. The light produced by the 9 high intensity LED bulbs is sufficient to maneuver around without fear of barking a shin or anything like that. It has a lanyard attached to it which is good for wrapping it around your wrist to ensure that you can have your hands free if you need them. There is a simple push button on the back of the flashlight that activates and deactivates it. The bulb is touted as a lifetime bulb, so I should never have to replace it. I haven't been able to verify that yet, but I'll get back to you... If you need some spare light for camping or emergencies, I'd highly recommend the Task Force flashlight.
