The Klarus G20 Dual Switch Flashlight is an impressive combination of power and practicality, all enclosed in a body no bigger than a can of soda. Less than 5 inches long and about half the width of your typical can of Coke, this compact light can easily fit in a bag for a convenient every day carry. Despite its small size, the G20 delivers power that would rival most larger high-performance lights, generating up to 3000 Lumens of brilliant illumination using its sophisticated CREE XHP70 N4 LED. In addition to its maximum output, the light comes with a trio of dimmer outputs ranging from 650 Lumens down to 15 Lumens, as well as a pair of tactical outputs, including a Strobe Function for disorienting a target and a S.O.S. Mode for signaling for aid in an emergency.

Convenient Design

While its potent output certainly stands out, its the G20's incredibly user-friendly design that truly sets it apart from its competitors. Powered by a single 26650 (Battery Included), this handheld illuminator features a special micro-USB charging port where it can be quickly charged without needing to removing the battery, saving its user time and eliminating any need to buy a charger. To make operation more convenient, the G20 comes with two switches, one on its tail cap and one on its side, both of which can be used to power the light on and off, as well as access all 6 outputs. The versatility of the dual switches allows the user to hold the light whichever way feels most comfortable and still easily operate the light. The Side Switch even doubles as a power indicator where you can monitor the battery's remaining charge so it'll never die unexpectedly.

Incredibly Durable

All of the G20's power and functionality would be useless without a strong, dependable body to ensure it can't be easily damaged. Crafted from sturdy aerospace-grade aluminum, the light's body comes with a hard-anodized finish that gives it incredible impact and water resistance, making it safe to use in just about any environment. The light's mineral glass lens is scratch-resistant and comes circled by a stainless steel bezel, protecting its powerful LED from any chance of damage. The G20 is even protected from harm internally, featuring an intelligent ITS temperature control system that helps prevent overheating from extended use.
