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.

Hisense adds AI-cameras to handsets
Hisense has entered the AI-camera space with the Infinity H30, aimed at the mid-range market. BRYAN TURNER tests the new camera technology.
Click below to read the review.
While many know Hisense for its TVs and appliances, it has an impressive lineup of smartphones. Its latest Infinity H30 smartphone packs a serious punch in the mid-range market, including features like a low-bezel screen and AI camera.
Out the box, the phone comes with the usual charger, charging cable and earphones. There is a surprise in the box: a screen protector and a clear case. A nice value-add to the already affordable smartphone.
The polycarbonate plastic body feels premium, especially for a device in this price range. It has a colour changing body, depending on the angle at which it is held. The colour of the device we reviewed is called Ice Blue, and shimmers in darker and lighter blues. Aesthetically, this is a big win for Hisense.
The 6.5″ screen is a narrow-bezelled FHD+ display with good colour replication. Hisense is known for creating colour-accurate displays and it’s good to see it continue this legacy in its smartphones. The shape of the display is interesting, taking some design notes from Huawei’s Dewdrop display with what Hisense calls the “U-Infinity Display”. It makes the phone look really good.
On the rear of the phone, one finds a dual-camera setup with fingerprint sensor. On the bottom of the phone, there is a speaker, a USB Type-C Port and a headphone jack. The speaker’s placement on the bottom isn’t optimal and the sound is muffled if one accidentally covers the single speaker area.
The 4,530mAh non-removable battery is very capable, providing a good 12 hours of medium usage (checking messages every half hour and playing an online game every hour) until it reaches 20%. The battery capacity isn’t the only power feature of the device; it runs on the latest Android Pie operating system, which includes AI power-saving software measures to keep background apps from using battery.
It is a little disappointing to see the device came with some pre-installed games. Fortunately, one can uninstall them. Hisense makes up for this by issuing Android updates and security patches as the come out. This, coupled with the MediaTek Octa Core processor, provides a good user experience for playing games and multi-tasking.
The H30 has a whopping 128GB of on-board storage, and it can be expanded even more with a MicroSD card. The 4G-LTE capabilities are perfect for most high-speed broadband situations, with around 40Mbps download and around 10Mbps upload in an area with good cell service.
The 20+2MP rear camera configuration is good at taking shots on Auto mode, but pictures can be better after figuring out all the camera modes available. There is a professional mode for those who want to be extra creative with their photography. It also includes a baby mode, which plays various noises to make a baby look at the phone for a better picture. The AI mode can be enabled to make full use of the processor in the device, and fif the camera mode to be selected based on scenes photographed.
The 20MP front camera performs equally as well. This camera is the reason for the U-like shape at the top of the screen. The camera app has beauty-face filters, for those wanting a slimmer face or smoother skin.
Overall, the Infinity H30 is a prime example of a good phone in an affordable price range. The camera is very capable, and the AI processing helps what would otherwise be a regular camera. The aesthetically pleasing colour saves the day, and makes this mid-range device look like a high-end flagship. The device is retailing for R5,499 from most major carriers.
Nokia 9 PureView pioneers new camera tech
Nokia packed five camera-lenses into its latest high-end flagship, but does more lenses mean better pictures? BRYAN TURNER took it for a test run.
Nokia is not new to the high-end mobile photography market. In 2012, it led Mobile World Congress (MWC) with its 41MP Nokia 808 PureView. This year, Nokia returned to MWC with its next PureView handset: the Nokia 9 PureView.
Instead of pushing megapixels, the mobile device maker chose to focus on intelligent exposure and sharp focus quality. It achieved this with a set of five cameras on the rear of the device – the most ever on the back of a handset. All of the lenses are 12MP f/1.8 lenses, and three of them are monochrome. The five lenses work in tandem to blend the best parts of a captured image. This is achieved through software image blending, which has been trained to know what’s good and bad about the image.
Lighting is dramatically improved with a monochrome sensor. About 2.9x more light can be captured with a monochrome sensor when compared to a conventional sensor. Huawei showed off the advantages of integrating a monochrome camera with the P9.
Why three monochrome lenses?
Detail can be captured at three different lighting settings, one to absorb a lot of light, one to absorb a little less light, and one to absorb very little light. These photos can then be blended into one great photo, without the user having to worry about setting the camera’s exposure manually.
Only five lenses have been mentioned so far but the back of the device sports seven holes. The sixth hole is for the flash and the seventh is for the depth sensor. This sensor captures the depth of an image, so autofocus can be a little sharper and focus depth on bokeh images can be adjusted after the picture is taken. This adjustment feature is especially useful when a subject’s hair has been “bokeh’d out”.
