Almost perfect.


In my line of work durability is not the only measure of a product. It must also comply with some safety restrictions. In most ways the Streamlight Argo C4 headlight complies & I personally like the build & performance. It's always hard to find a product that would fit perfectly in any type of situation. I know this one came close.
