Dual Purpose LED's

The Klarus RS20 features a unique layout that offers both an ultra-bright primary LED and a built-in diffused LED mounted to the side of the light. The two lighting systems offer the best in long-distance outdoor lighting and even close-range illumination. Powered by two separate switches, the RS20's LED's can be accessed rapidly and independently from each other. The primary LED is fitted with a smooth reflector and generates up to 1050 lumens in its highest mode. The side-mounted LED is constructed around a purpose-made diffuser and produces 220 lumens of smooth lighting.

Colorful Versatility:

The RS20's unique design can be altered at your convenience for the ideal set-up. The White side-mounted LED (Included) can be swapped out with optional red, green, or blue LED's, each with their own tailor-made diffusers and unique lighting properties sought out by hunters, hikers, and law enforcement. The side-mounted accessories can be replaced with the use of a small Torx screwdriver (Included with diffuser).

Excellent Flashlight
I have been using this flashlight for over a year now. I use it around the house, in the shop, for self defense, and I have used it on camping trips. It is very powerful and that 1050 lumen power was very useful walking dark paths at night while camping. It's a blindingly bright light at full power and at most of the lower settings. The light was steady and did not exhibit flickering or other variations. It takes many kinds of batteries but the rechargeable feature is the reason I bought it. It works great. I charge from a 12 V DC regulated power supply with a 12 v to USB converter. While camping I charged it from the truck's cigarette adapter with my 12v to USB converter. This makes it very easy to keep the flashlight powered up. The side light is very useful for throwing a diffuse light. You can set the light upright and use the side light for many shop tasks and other lighting needs. Very smart feature.

There are two things I don't like but neither is a showstopper. #1... the belt holster. too small to fit the light. Somebody was asleep when they designed the holster which, if it fit right, would be great. #2... The controls require holding the buttons for a different periods of time to perform different functions. This allows two buttons to do all kinds of different things which is great. But it can be confusing. As a tactical light I wish they had a button near the end of the light which did one thing... activated the strobe. In a self defense situation you don't want to be fooling around trying to remember what sequence to push or how many seconds you have to hold a button down to get what you need.

If I could give a 4.5 star rating I would give this 4.5 stars. But since these are relatively minor flaws I have given the light 5 stars and recommend that others consider purchasing it.

Ok Light
This sounded like a light I would like to own considering the amount of features it has. It appears to be well made and should be durable. I found it to be larger and heavier than expected and I don't see carrying it. It will be placed where I expect to have a need for a light with more output than my EDC. Additionally, you would think for light costing over $100 the manufacture would include a higher capacity proprietary battery.
The 3400mAh batteries cost you an additional $20.
ProsEasily Rechargeable
ConsCost for value. Low capacity PROPRIETARY battery

Capable Multipurpose Flashlight
I ordered this flashlight for my son for Christmas based on prior reviews and the Battery Junction writeup. Wow, is this flashlight versatile! Not only is the main beam bright at 1050 lumens, but the walking/area light feature is equally as useful and fun.

The fact that a user can light the main beam in addition to the floodlight really helps illuminate particularly dark campsites, trails, etc. The magnetic charger that comes with this light works excellent, and charges the rechargeable battery (included) quickly and easily.
ProsExcellent beam at 1050 lumens. Area floodlight is even more useful than the main beam in many applications, and the color and adjustable output are spot-on. Cree LEDs are known for their high quality and efficient output in terms of lumens per watt.
ConsNone, this light is easily the go-to favorite for our household and is the best, most versatile flashlight we own.

Awesome flashlight, but...
The Klarus RS20 is an awesome flashlight. Although it lacks the versatility of some of the Nitecore products (the SRT6 for example) with the Smart Selector Ring (that enables for an infinite variation in light output), the switches make intuitive sense and the side-mounted LED is very useful to illuminate an entire room. The magnetic charging system is amazing.

But the belt holster is a joke--it's too small (you need to pull the head of the flashlight through it to the point of ripping in order to secure it) and doesn't afford any protection to the flashlight.
ProsBuild quality Charging system Charging the battery (Klarus only) in place
ConsBelt holster is poorly designed

How much does the RS20 weigh? Is the front lamp reflector a spot beam?
1 Answer
The RS20 weighs 6.7oz (190g). Yes, the reflector produces more a spotlight, while the side light is more of a floodlight.

I understand that to use the charging system you must use a special Klarus battery. From what I can tell you do not stock the one included in the package, so do either of the other two Klarus batteries that you do carry work in this with the charging system?
1 Answer
We received the Klarus 18650 3400mAh and Klarus 18650 2600mAh, which are the Smart batteries and will charge inside the RS11 and RS20.

What is the UI on this light....is it moon>low>med>high? or the opposite?
1 Answer
The UI starts out in what ever level light you used last (memory). So if you were in low mode (more than 2 secs) and then shut it off, it will start out in that mode. A quick press from that mode will then take you to high/med/low/moonlight. The switch has a momentary mode were you need to hold it down for 1-2 secs before it will stay on thus giving you a momentary mode in what ever level you used last. A quick double tap from off will take you in to instant strobe mode. This is true for both the main and side flood.
