JETBeam KO-02 Flashlight

The JETBeam KO-02 is a professional EDC with all the bells and whistles you'd want from a modern flashlight. We're talking five versatile brightness modes ranging from 1800 to 12 lumens and a tactical strobe that keeps an attacker at bay. The IPX-8 waterproof rating and 1m impact-resistant aluminum alloy exterior ensures your light remains intact on your hiking or camping adventure. The KO-02 also doubles as a handy adventure or searchlight with its nearly 900ft throw. The four-tiered LED indicator keeps an eye on your battery level for you, and automatically scales down the brightness to extend the KO-02's work life. If you manage to exhaust the 140 hour runtime, a convenient built-in USB-C charging port offers quick-access charging for the included 21700 battery.

Excellent Light

Works very well and is bright!

Don't got no change-ability!!
December 27, 2019
If you don't mind not being able to change the user modes or the fact that it comes on in the "ludicrous mode" (re: Spaceballs) or that there is no "moon light" mode, or that you can't get but one tint, this is a dam fine light!

For most people this is going to be an amazing light!

It has a good range of brightness modes that will fit almost all situations that "normal" people use a light for.

The low is about what an old carbon battery flashlight was 50 years ago but with the 21700 battery it will run for days!! This makes it a fantastic emergency light. Just stand it on end and point it at the ceiling and the room is lit like it was with my Granny's old kerosene lantern on low flame!! Can't read a book but you won't be running into furniture either!

On Turbo you light up the world!! The pictures are representative of what I experienced.

I have many lights, some with a great deal more output than this one. Most of those are much larger than this one requiring two or more batteries. I have paid more for batteries for those monster lights than I paid for this light with its battery included. They also don't fit in my pocket. For the pocket size lights that have a similar output, this KO-02 can stay brighter longer than my other lights until it gets too hot. Good heat dissipation.

I have been looking for a light with a 21700 cell. The fact that this one had USB C charging, great for the car, and was a BlackFriday special sold me. I already have some JetBeam lights so I knew that it would be a quality piece. What I didn't know was that none of my chargers would fit the longer 21700!! It never crossed my mind! I really prefer a charger that tells me what the voltage of my cell is so I can get a rough idea of how my usage affects the battery. I don't like running them too low. The built in LED battery level indicator helps with this concern.

If you want to try out the 21700 cell, in my opinion, this is a good light to start with. You get a usable range of brightness's with a monster turbo and USB C charging. A bit larger than an 18650 light but not much. A good light I think!

Not what I expected
December 26, 2019
Spending $50 on a flashlight is not what I normally do. I've had impressive lights for under $20 so figured at $50 it would 'blow the cheap ones away'. Was almost ready to get my money back because it really did not have that great an improvement for the higher cost. Sure it does throw out a lot of light but the lack of sharp focus was disappointing for me. There is no focus feature so is really only useful for filling a room with light but not for long range illumination.

I will keep it and find a limited use for it since the rechargeable feature keeps the battery expense low.

Great Light for the price! Very Bright!
December 11, 2019
This light is VERY Bright! Easy to use too! It DOES remember the last setting as well. The battery included is 4000Mah. Take a long time to initially charge. Expected. Not a negative at all. Battery Junction got it to me pretty fast too! Great People!
