This is essential edc gear! - Streamlight MicroStream LED Pen Light w/ 45 Lumen Output

I was skeptical when I bought the first one of these amazing little gems. Now I seem to keep buying more after giving them away to family and friends. Why? There can always be one clipped into a pocket, ready for use. They are adequately bright for most any emergency. The switch requires a positive push to actuate so I have NEVER had one turned on and the battery expended by accident. They are rugged with a durable finish, waterproof (a friend has run his thru the washer, clipped into his coveralls, three times that I know of. Without harm.), and contrary to some reviews I have seen, mine have survived some pretty hard impacts without notice or even surface damage. But the best recommendation is that they are handy enough that mine is almost always on my person when I need it. Super Gear!
