This is a Pac-Lite, a two LED light that clips onto the end of a 9 v battery. It is a no frills, no nonsense tool, durable, reliable, and compact. I brought it on a trip camping around Iceland in the winter, followed by eastern France, Switzerland and some other places. It was soaked and exposed to both nearly scalding water in steam caves, as well as freezing temperatures and salty conditions of sailing. The battery life is extremely long. I never had to replace it during three months of traveling and frequent use. It has a three position toggle switch as its sole control: off, high, low. It can however be bumped accidentally and turn on inside a bag. I did not have the neoprene head strap for it, but I would recommend it. I frequently tucked it under the side of a bandana, or even held it in my mouth a few times while working with both hands. It is not a spot light, so do not expect it to light up a moose on the far bank of a river, but it is an excellent task light to have on hand or keep in a survival kit.
