In this Klarus G20L review I’ll share plenty of detailed photos and my impressions of this flashlight. This is the largest and brightest flashlight I’ve reviewed to date. Is this truly a “tactical flashlight?” Yes and no. It’s too big to easily carry in a pocket (unless you are wearing tactical or cargo pants). It definitely needs to be carried in a holster. But, unlike many larger flashlights that operated via a side switch, the G20L has a tail switch as well, so you a choice to operate the flashlight with either switch. The Klarus G20L has become my nightstand flashlight. It’s absolutely perfect for that application.
The G20L is IPX8 rated so you can use it in the rain without damaging the flashlight. It features a nicely knurled body to ensure a good grip in wet conditions as well.
Note: In the interest of full disclosure, the Klarus G20L used in this review was provided to me by FlashlightZ.com. FlashlightZ.com is a small flashlight company located in Tulsa, OK. You can learn more about them via their social media accounts on Facebook, Instagram, YouTube and Twitter. They also sell their flashlights via Amazon.com as well.
The Klarus G20L is 5.91″ long. It is very ergonomic and fits comfortably in the hand.

Klarus G20L review – Quality of light
I think the key thing you need want to be aware of is that this flashlight’s output is “floody” rather than focused. I think the tendency is to immediately think “wow, at 3000 lumens this thing should be a light saber.” It’s not designed to be that kind of flashlight. In Turbo mode (3000 lumens) it’s rated at 300 meters. It’s meant to combine a great deal of throw WHILE lighting a broad area at the same time. Instead of a focused, intense beam you have a broad beam with good side-to-side illumination and little edge fall off.
If you are looking for a light with a ton of throw you’ll be underwhelmed. If you want that nightstand flashlight that you can grab and go outside and check out the WHOLE yard (not just a pin point spot in the yard) this is your flashlight. The wide flashlight head and orange peel silver reflector are typical in a flashlight of this type.
The LED was well-centered within the orange peel silver reflector. The LED is the latest edition CREE XHP70.2.
Klarus G20L charging and battery
The Klarus G20L is charged via a micro USB cable which allows you to just leave it in the flashlight. It took at least ninety minutes to get a full charge out of the box. The battery is a 5000mAh 26650 rechargeable. You CANNOT use CR123A, 18650, or 16340 batteries. The battery is huge compared to most other rechargeables.
This really gives you an idea of just how big the lithium rechargeable battery for the G20L is.
Klarus G20L user interface
I really, really like the Klarus G20L user interface. You can either use it “tactically” – holding it in your hand and operating the lighting modes with the tailcap switch or more conventionally to cycle through the lighting modes with the side switch. It’s your choice. Typically, large flashlights lack a tailcap switch. From a tactical perspective this flashlight is more of a search type light, not a self-defense type light.
The side switch is easily accessible. Simply click and release to cycle through the lighting modes.
The tail switch is easy to access as well. Press and release to access the various lighting modes.
Klarus G20L battery run times
Turbo: 3000 lumens, 45 minutes
High: 650 lumens, 4 hours 30 minutes
Medium: 160 lumens, 19 hours
Low: 15 lumens, 150 hours
Strobe: 3000 lumens, 1 hour 30 minutes
SOS: 160 lumens, 51 hours
I added this photo to help you get a good feel for the true size of the G20L. Here it is between a mini-EDC flashlight and a mid-size tactical flashlight.
Klarus G20L Review – Conclusion
The Klarus G20L is my nightstand flashlight. Like most flashlights it has it’s own niche – a solid, all-around, general usage flashlight with a very bright, broad floody throw with even side-to-side illumination.
- Great ergonomics
- Side switch or tailcap switch mode control
- Broad, bright flood for even side-to-side illumination
- Exceptionally well made
- I wish it used a dual tailcap switch so you have instant on strobe
- It’s big… so you need to know it carries in a holster, not a pocket.
Should you buy it?
If you need a excellent, general purpose flashlight then this is a great choice. If you need a more tactical, everyday carry type flashlight you’ll want to consider other Klarus models (like the XT12S or XT2CR)
