Streamlight | CR123A Lithium Batteries

Streamlight's own CR123A lithium batteries are the cells its weapon lights and handheld flashlights are actually engineered and rated around, so you get the real advertised runtime and output instead of guessing how a generic battery will perform. They hold a shelf life of up to 10 years in storage, which matters for a battery that might sit in a duty light or defensive pistol for months between uses. A straightforward, trustworthy way to make sure the light you're depending on has exactly the power behind it that Streamlight designed it to use.
