Conclusion: Good little all-around close-range light. Great output for a single white LED, and the other modes can serve specialty purposes. The red lens reduces output tremendously and is great in very dark situations. I'll give it 3½ Stars for versatility and durability, but water resistance of the front end needs to be improved a bit in my opinion.
Pros: Water resistant, Impact resistant, Long battery life, Good output, Easy battery change, Lightweight, Stands up
Cons: Not water tight - use compressed air to blow it out if it gets too wet, or open it up and let it dry in the sun.
