The Anatomy of a Flashlight


Most torch lenses are made from scratch resistant glass. It’s important to keep your lens as scratch free as possible because it is the final barrier between your light source and the world.

Some torches have a raised bevel around the lens to keep debris away; another option is to keep your torch in a holster, especially if you keep it in a vehicle where it is bound to roll around.


Reflectors come in two types...

-Smooth reflector: Ideal for a long throw, helps direct the light into a strong spotlight
-Orange Peel reflector (OP): Ideal for a distributed beam with a wide angle.


The LED is where the light is emitted from and therefore is one of the most important parts of a torch. A vast majority of high performance LED’s are manufactured by CREE.

LED lights can vary in colour from “cool white” (the whitest beam) to “neutral white” (a slightly “warmer” more yellow beam, more ideal for hunting etc where you need more accurate depth perception at long distances)

New LED technology is constantly developing, you can check out this article for more information


The driver is a small transformer that takes the energy from the battery and makes it into a usable form of power for the LED.

The driver is also responsible for any modes the torch may have, such as SOS mode, Strobe mode or high, med and low modes.


Most advanced LED torches are powered by rechargeable lithium batteries.

These batteries come in various sizes with “18650”s being the most popular / industry standard for most advanced high output devices. They have a high output, a long run time and can typically be recharged around 500 times.

Protected batteries – Lithium batteries are volatile / can explode if shorted out in a bad way. “Protected” lithium batteries have an inbuilt protection fuse that runs down the side of the battery. In the event of a short circuit this fuse will blow before the battery will have a melt down.

The switch turns the torch on and off, and also controls the modes (e.g strobe, high, med & low -for torches that have modes). Most switches are located at the rear tailcap of the torch, but can also be found towards the front of the torch handle torch where you would place your thumb.

Most switches are covered with a replaceable rubber membrane that makes them waterproof and long lasting.

There are two types of switches:

Basic switch: A basic switch simply works by clicking it on and off. Often you can change output modes on the torch by turning it on and off a few times.

Memory switch: A memory switch is the high tech brother of the basic switch.
Often you can program certain commands to turn on certain modes. e.g) hold down the switch for 2 seconds and it goes straight to strobe etc.

More about the Amazing Klarus Mi7 Flashlight

700 lumens coming from a flashlight that is smaller than a pen – just let that sink in for a minute or two. Then take a look at the awesome Klarus flashlight, the tiny, yet elegant Mi7.

If you thought you’d seen the last of the AA flashlights, since manufacturers have focused more on the 18650 battery, you’re wrong. Clearly Klarus haven’t forgotten about the die-hard fans of the AA battery.

The Mi7 comes in three striking colours and accepts two types of AA-sized batteries. The AA primary allows an output of up to 330 lumens for 55 minutes, and using a 14500 li-ion rechargeable battery more than doubles the output to 700 lumens.

Three levels with SOS/moonlight modes are controlled with a side-button switch, with one-touch access to the latter modes as well as a battery level indicator.

What about carrying the Mi7 around, won’t such a small flashlight be easy to lose? No ways! Carrying the Mi7 is easy thanks to the keychain friendly o-ring on its tail and its hard anodized aluminium body ensures that it doesn’t get damaged when in use.

Have your gotten over the 700 lumens from a flashlight of this size yet? If so, pick up the Klarus Mi7 from the Klarus website or email sales@klaruslight.co.za
