The Surefire S2 Stratum is usually the light that I point outdoor users toward when they want a Surefire and don’t want to plunk down the cash for an AZ2. The Stratum has three brightnesses, 5, 50, and 160 lumens, covering almost any lighting need that the average outdoorsman has. Unlike many of Surefire’s other lights, the S2 starts on low, so you have to cycle through the two lower brightnesses if you want that max brightness. The lower brightnesses will get you better battery life and are great for up close and in camp tasks.
