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, 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.

Perfect for multi use
December 24, 2022
Size is nice and small for running a 21700 battery. UA easy and understandable. I have mostly 18650 lights but this is the only 21700 due to it's small size. As with other Jetbeams it is a great mix of flood and spot due to orange peel reflector. Wish I would have bought 2.

Super bright for the size
December 20, 2022
This is very bright
Great size and feels great in the handle.
Only thing I’d like to see is a pocket clip or a larger lanyard ring.

This is my 2nd. KO-03 and I love the light. Does exactly what I want in an everyday carry. Except for wanting to turn on in your pocket because of switch level I couldn't be happier.

Lifesaver, great quality flashlight
October 19, 2022
My daughter bought this for me, I keep it with me in the car and it's saved me multiple times now. Once when I was waiting for a tow and my phone was dying. I forgot I had a charger right there in my flashlight! Thank god. It's nice and compact so it doesn't take up too much room, but let me tell you it is still BRIGHT.

What are the run times for the top three light levels when the protection curcuit lowers it? Also, the light outputs and the run times after the light lowers its output.

Thank you for contacting us. Per JetBeam - Onthe turbo mode, the KO-03 keeps at 2400 lumens for 1 minute, then drops to 1200lumens for 6 minutes, and then drops to 750 lumens.
