I can’t really find anything all that informative on this product but took a chance on it and was seriously impressed as were my peers in the firearms business. Although I imagine this was never thought to be used in this context. I found this tool to be nearly ideal in the use of firearms as the light is more than adequate (I estimate around 60 lumens) and the flexibility of the shaft allows to get into some pretty hard to reach places (22″). Magnets (pretty strong!) are at either end and allow for the occasional retrieval of an item or can support its weight enough to provide impromptu light in a pinch. Highly recommended!!!
