JETBeam KO-03

Next Generation Lighting

The JETBeam KO-03 is the next generation in the KO series of flashlights. The KO-03 is an upgrade from the very popular JETBeam KO-02 V2, now with a Luminus SST-70 LED, longer run times and more functionality. With almost the exact same body design, this light puts out 400 more lumens and lasts over 200 hours longer than its predecessor.

Fuel Options

The KO-03 is gives users multiple fuel options for their convenience. The package includes a JETBeam 21700 li-ion battery, but can also be powered by 1 x 20700 or 1 x 18650 batteries. When using li-ion batteries, the KO-03 has the unique feature of providing a power bank function with the discharge of the battery. Charge up essential electronics in a pinch with the flashlight already in use.

Flat, Magnetic Tailcap

To ensure ultimate efficiency in different environments and work places, the KO-03 has a flat, magnetic tailcap. Use this light on flat floors or surfaces for tail stand lighting when broader lighting is needed. Attach the KO-03 to metal surfaces with its powerful magnetic tail for a hands-free lighting device - often needed in power outages, auto emergencies and utility work.
