Klarus LED flashlight reinvents the handheld torch

Two new LED flashlights from Chinese company Klarus prove that the torch is no longer merely a tube with batteries, writes Joel Dorfan.

Klarus Lighting Technology based in Shenzhen, China, is one of the newer flashlight innovators and manufactures to take advantage of what LED’s have to offer to the handheld flashlight industry.

The flashlight is no longer just a tube with some batteries, a lamp and a switch. LEDs combined with electronic circuitry have allowed the flashlight to become a really useful tool.

Long runtime and low output, shorter runtime and high output, strobe modes and many more functions are now possible out of a single product.

Boost circuitry now allows the use of a single battery to power lights with enormous output.This means no longer having to leave the light at home or in the car.

Klarus have used the latest generation of Cree LEDs in two new lights: the XP-G2 and XM-L(U2). The RS1A will give you up to 210 lumens (100m beam distance) and the RS11 up to 620 lumens (160m beam distance).

The AA battery form factor of the RS1A makes it easy to carry in jean’s pockets, with the larger 2xCR123 form factor RS11 allowing for easy jacket pocket carry.

Klarus have included features in these two lights that would appeal to the everyday user. For one thing, it has a body mounted switch rather than a tail cap switch. By doing this, they have left the real estate at the rear of the light available for the charger connector.

As versatile as these lights have become, this is not really a one-size-fits-all. You would still need to decide what the primary purpose of the light will be, choose the appropriate product whose primary function suits your need and then have the other functions as a bonus.

Law enforcement officers may require a light that always comes on as bright as possible the first time it is turned on without fiddling through modes and a tail cap switch (Klarus XT series).

The home user may want a light that comes on in a lower mode but then be able to ramp up the brightness as required. Whereas maximum output is important, LEDs with electronic switching are now able to give you really low output as well.

This is useful in the middle of the night when you just want a little light without waking up the family or when you need really long runtime in the event of a power outage. The RS1A will give you up to 68 hours and the RS11 up to 215 hours on a single fresh battery.

These two RS series lights from Klarus have an innovative charging setup. Both lights come with a charging cable that has USB plug the one end and magnetic plug the other end.

The magnetic plug automatically locates snapping into place at the base of the light. Many products these days will charge using a standard USB port, so why should flashlights be any different? To charge the battery you plug the cable into any USB power source.

This could be a USB port on your computer, cell phone charger or the USB receptacle in your car. Lwet’s see how it does on the gadget

Five Question User Test:

1. Is it ready to use?
Neither light comes with a battery. To make use of the charge function you will require a rechargeable AA battery for the RS1A or a protected 18650 LiIon cell for the RS11. Both lights will run on primary cells, which for the RS1A are standard alkaline AA batteries and for the RS11 2xCR123s. 

This is a useful feature should you run out of charge and not be able to recharge the cells. Both lights come with detachable pocket clips. This is a great idea if you don’t like pocket clips.

However,I found them both to be a little flimsy and failed to grip the pocket positively. They are also located quite far from the tail cap, not allowing for deep pocket carry.

They do both however come with lanyards and a decent cordura pouch that can be worn on the belt or just used for protection for bag carry.

2. Is it easy to use?
The lights have 4 modes. High, medium, low and strobe. The user interface to change modes can take some getting used to.

The RS1A has a single button on the body. A momentary press and release will cause the light to come on and then go off. Hold the button down for just over half a second and the light will stay on. Once on, if you then hold down the button the light will move to the next mode.

You then need to release the button and then hold it down again to move to the third mode. Double click the switch at any time to access the strobe mode. The RS11 has two buttons on the body: A larger raised front button that will act exactly the same as the button on the RS1A to access the 3 brightness modes; and a second more recessed button to access the strobe mode.

Both lights have last-used memory feature. This means that whatever level you had the light set on (for longer than 3 seconds) when you switched the light off, will be the level that the light will come on in next time you turn it on. The manual that comes with both lights is adequate but changes need to be made to explain the operation of the lights more accurately.

3. Does it deliver on its promise?
With the exception of the slightly fiddly user interface mentioned above, both lights are excellent. Machining and anodizing are perfect. They will both handle some fairly harsh use and continue to function flawlessly.

Both lights are rated IPX8 waterproof to 2m. Beam pattern and throw are outstanding for any light let alone for lights of this size. Both lights tail stand perfectly, allowing the light to be bounced off the ceiling for more flood-like application. The stainless steel bezels on both lights are easily removed allowing for a slightly more slim lined and less aggressive look.

4. Is it innovative?
There are many up and coming flashlight manufacturers, but Klarus are the first to have the magnetic charging feature. No external DC sockets means nowhere for dust or water to get in. USB chargers have become so common that providing you have the proprietary charging cable, you should always be able to find somewhere to plug it in. Many rechargeable products use a proprietary battery.

These two lights will even run on standard primary cells easily available from your nearest battery store. In all of their higher end lights, Klarus have gone to a lot of trouble to include an easily accessible strobe mode but, at the same time, have found ways to prevent accidental activation.

5. Is it value for money?
At a suggested retail of $74.95 for the RS1A and $116.95 for the RS11, these lights are not cheap. However if you look at all of the features on offer, you are getting a lot of light for you money, especially if you factor in the fact that they are both rechargeable. – gadget.co.za
