Flashlight Tools

The question every buyer asks is "which light should I actually carry?" These free, interactive tools answer it from the use case and the spec data — match a light to how you’ll use it, and confirm the right cells and chargers before you buy. Each carries a "How this is calculated" note citing the ANSI/NEMA FL-1 definitions (lumens, runtime-to-10%, peak beam intensity in candela, throw = 2 × √(candela) metres) and community-measured data sources — never our own lab. No review claims — just the data.
