Great little flashlight, small enough to put in any pocket and runs on our favorite battery a "AA" that we can recharge as opposed tot the expensive, but excellent and high lumen Surefire flashlights that run on a DL123 or CR123 type battery (not rechargeable).
We think one or two Surefire in medium lumen (60 or so) and high Lumen output (120+) are great and essential Survival Equipment to have, especially when combined with a firearm and used when lighting up a search area, but in a collapse you will rapidly run out of batteries unless you stockpile a butt load of them and even then the batteries can degrade. We have based on light, both flashlights and lanterns around AAA or AA batteries since they can easiy and quickly recharged through a 12 volt system.
The Gerber Oynx is small (see the scale photograph against a dollar bill); put outs acceptable light for most tasks (30 lumens); has a LED instead of a bulb which is breakable; in-expensive at around $20; works on one (1) AA battery; and, has a push button on/off tail cap.
The Gerber Onyx is well made in an aluminum housing and the housing barrel is flattened for a better grip Great piece of Survival Kit and well priced.
