Size: It is crucial for an EDC to be small, compact and light
Build: EDC flashlights need to be built strong to handle being carried around all the time, especially when they are attached to a keychain
Battery Life: It is important to have decent run time. The longer the runtime the less likely your battery will be dead when you need it most- in the dark! Flashlighthut recommends having at least 4 hours of run time.
Modes: Having a "low" "medium" and "high" setting can be very useful. No need to waste precious battery life by blasting your EDC on high when you don't need that much light. People fail to realize that the darker it is, the less light you need.
Our Recommendation: The Dereelight C2H. It has great runtime, built strong, very compact in size, and it has 3 different modes. What makes it stand out from all the rest? It comes with a free extender that allows you to use AA batteries if you don't want to use CR123A batteries.
