UPDATE: This is not as waterproof as advertised. I was using it for a couple hours in a very light drizzle, more like a gentle mist, and when I opened the back charging port to charge it at the end of the night, the port was really wet inside. I had the orange plastic piece secured all night, and checked it several times over the evening, because I was nervous about water getting inside. The light still worked just fine, but, the plastic/rubber piece over the charging port did NOT keep water outSee full review
