Armytek Predator 

- rich performance in a compact and stylish package, displayed through exceptional technical 

characteristics. Initially developed as a hunting and Special Forces flashlight, but perfectly suitable for any indoor or outdoor 
activity due to its size, ruggedness and design specifications. It is the only flashlight of the newest generation, possessing new 
optical components and advanced electronic capabilities.

The differences between Armytek Predator and other compact tactical flashlights:

1. 

Impressive optics - excellent compact thrower, maximal distance for this size of flashlights with reflector.

2. 

The completely new second-generation driver S-Tek™ enables the flashlight to emit a bright and constant light even when 

the battery 18650 Li-Ion is almost discharged. S-Tek™ is the only driver in the world that enables the user to choose the 
type of stabilization.

3. 

Easy manipulation of modes and the possibility of full settings ability to fit your needs: many parameters can be changed - 

the brightness, the number of modes, the strobe frequency, the battery type, the type of brightness stabilization, the type 
of automemorization etc. However, if you don't want to change default settings – you can use ArmyTek Predator as an 
ordinary flashlight immediately, because it is ready after preparing on the factory.

4. 

Complete compatibility with LiFePO4 batteries, which can be fully charged in 10 minutes. In this flashlight LiFePO4 can be 

used safely for the batteries.

5. 

It is the only flashlight in the world with doubled critical electric circuits. Even when the main circuit is damaged, the system will be 

able to work on the reserve circuit, emitting light during 130 days, which enable the user to survive in an emergency situation.

Main factors were considered during development:

1. 

Light. Powerful, long-distance beam, compact optics.

2.

 Electronics. Effective and highly advanced.

3. 

Design. Comfortable and compact, light and reliable.

The flashlight is developed and engineered by 

Armytek Optoelectronics Inc., Canada

. Made with USA and Japan electronic 

components. During development, ideas and suggestions from European and Russian engineers, Special Forces and 
experienced hunters were used to the full extent.

The ArmyTek Predator flashlight is a complex product of technologies. To ensure correct and long-lasting operation it is 
necessary to perform servicing.

1. Switching modes, setting up the flashlight and other functions are realized through a gold-plated contact ring. To ensure 

a correct operation of the flashlight, the ring must be periodically cleaned (as it gets dirty), as well as the adjacent areas 
of the circuit board, from dirt and the lubricant.

2. To improve the flashlight's water resistance it is necessary to periodically clean (as it gets dirty) the thread off old 

lubricant and grease it again. Nyogel 760G is preferable: it is dense as gel, non-conductive, water resistant and not 
corrosive to the rubber. 

3. If you noticed that the flashlight is acting out, not responding to your commands, the light flickers etc., the first reason is 

to change the batteries, and the second reason could be the contamination of the contact ring and the thread with the 
old lubricant and traces of aluminum dust. 

4. The clip can be removed after the tailcap of the flashlight is taken off and both O-rings are removed. 
5. Use high-quality batteries to prevent the elements leakage inside your flashlight and other destructive effects. Remove 

batteries from your flashlight if you do not intend to use it for a long time.

Electrical Features

The flashlight has been designed on the basis of the new-generation electronic driver S-Tek™. The S-Tek™ driver saw the 
first industry use of technical solutions, which enabled the realization of unsurpassed features:

1. 

The current stabilization types are entirely changeable through the user menu: full stabilization (FULL), simple semi-

stabilization (SEMI), stepped stabilization (STEP).

2. 

Firefly mode 0.1 lumens, working for 130 days with ONE 18650 Li-Ion battery.

3. 

Complete compatibility with one 18650 battery: actually high efficiency, long duration and flat runtimes (graph of 

brightness which depends on work time) with full stabilization of the current at all modes. Important notice: an 
implementation of buck-boost technology allowed refusing of standard method to reach constant brightness by addition of 
second 18650 battery that made the flashlight 2 times more compact and lightweight.

4. 

Advanced electronic protection from incorrect battery installation, without reducing the efficiency of the driver

5. 

Constant and smooth light output. Important notice: no irritating flicker effects.

6. 

Ecological algorithm of the stabilization control S-Tek Green™, which decreases the system power consumption, making 

the flashlight very effective, completely utilizing the battery power. 

7. 

The S-Tek™ driver, due to a built-in sensor, constantly monitors the temperature of LED and the electronic circuit and will 

prevent the LED overheating in extreme environments.

8. 

The driver has a built-in indication of low voltage and high temperature.

9. 

The voltage supply selection allows using the cheaper batteries without protection board (PCB), for example: LiFePO4 or Li-Ion.

6. 

The ability to reset of all settings of the flashlight to those built-in by the manufacturer (Military or Outdoor presets) or to 

the user's saved preset (Custom).

7. 

Protection from switching on accidentally (special turn of the tailcap).

8. 

Strong and easily removable lanyard to avoid losing the flashlight.

Mechanical Features

1. 

The flashlight has a strong, difficult to break body, which is developed for a minimum weight with sufficient durability. The 

design of the body includes element design specifically to prevent the flashlight from rolling. 

2. 

The flashlight is designed with the impact-resistant bezels from both sides in order to protect it from falling and allow 

utilization during combat situations. In the Gold and Black version the steel bezels are also covered by titanium compounds 
with a hardness of 2000-3000HV.

3. 

To ensure functionality in difficult conditions, the electronic driver of the flashlight is placed in a special aluminum capsule 

and has been completely covered with a durable compound. This actually protects it from both the environment and from 
mechanical damage.

4. 

Body cover: matte, anodized. Hardness: 350-400HV. Resistant to scratches and impacts.

5. 

Body material: aviation-grade aluminum T6061-T6. 

Water resistance

 

Water resistance standard: IPX-8 (the highest)
The following technical solutions were implemented to improve water resistance of the flashlight:

1. 

Two silicone O-rings are installed at each side of the battery tube of the flashlight.

2. 

Metric profile thread has been used.

3. 

An O-ring has been used to increase glass 

sealing

, and well as an extra L-ring of a specific shape.

4. 

All threads, rubber parts and other parts of the flashlight that experience friction or contact with water are lubricated with 

a special dense grease NyoGel 760G.

Power source:

 primary or rechargeable batteries, used to supply the operation of the flashlight.

Driver: 

the electronic circuit used to operate the flashlight and to support the functioning of LED.

The protection from accidental switching on:

 the function of the flashlight preventing it from being turned on by pressing the 

button. For example, when it is being carries in a back-pack and there is a possibility of contact between the switch button and 
other items. This function enables the prevention of an accidental switch-on, and an unplanned loss of power.

Warning indication: 

a warning blinking, signalling a low battery voltage or a high temperature of LED. It blinks 3 times every 60 

seconds.

Important notice: If the user is not reacting to the warning blinks (for example, does not switch the flashlight to a lower mode 
to save energy or reduce temperature), then when the critical levels are reached (low voltage or high temperature) – the 
flashlight automatically switches to the Firefly mode. At the same time the user retains control of the flashlight. However, one 
must understand that when the battery is fully discharged – even in the Firefly mode the user loses control of the flashlight.

Full pressing: 

pressing the button of the flashlight until a characteristic click, which confirms its fixing in this state. The lift of the 

stem of the switch amounts to 0.12-0.16"/3-4 mm.

Easy pressing:

 pressing the button of the flashlight without fixing it at that state. The lift of the stem is 0.02-0.06"/0.5-1.5 mm.

Ordinary switch-on: 

switching the flashlight on by a full pressing of the button.

Tactical switch-on: 

switching on the flashlight using easy pressing of the button.

The head: 

the front part of the flashlight, which includes: front steel bezel, glass, reflector, LED, driver and the casing of the head.

The body: 

middle part of the flashlight, including: the casing of the body (battery section), the clip, and silicone O- rings.

The tailcap:

 rear part of the flashlight, including: the casing of the rear part of the flashlight, the button and the spring, silicone O-

rings and back steel bezel. 

Mode Lines: 

if you unscrew the head of the flashlight from its body, you can see the gold-plated contact ring. When screwing the 

body of the flashlight into its head, the end of the body may or may not touch the ring. In both these states current reaches the 
circuit board. This enables the creation of two independent Mode Lines: First Line and Second Line.

First Line: 

this sequence of modes is available when the contact ring touches the end of the body of the flashlight (there is an 

electric contact).

Second Line: 

this sequence of modes is available when the contact ring does not touch the end of the body of the flashlight (no 

electrical contact).

Automemorization of Modes: 

the ability of the flashlight to memorize the mode in which it was switched off. At the following 

switching-on of the flashlight it starts operating at that specific mode. The function of automemorization can be turned on (the 
flashlight memorizes the last mode) or off – in that case the flashlight does not save the mode in the memory and always switches 
on in the first mode of the Mode Line. This setup can be turned on or off for each Mode Line separately. If Automemorization of 
Modes is on, the flashlight stores it in its memory even without the power supply.

Indication of battery voltage: 

the function of the flashlight showing the voltage of battery at the actual moment for the current 

mode. The voltage of battery enables the user to indirectly determine the amount of operating time left.

Micromode (Firefly): 

special mode, based on LED microcurrents. Has a very low brightness compared to regular modes and a 

long runtime (up to 130 days).

Important notice: the micromode is mostly intended for use in critical situations, since its extremely low energy consumption 
enables up to 130 days of operation. At the same time its brightness is sufficient for walking, for example. Besides, the goal of 
micromode power supply is doubled: when the main power circuit is damaged, the micromodes will continue functioning 
through the reserve circuit.

Constant light: 

light output, not interrupted by any pauses, sudden increases/decreases in brightness etc.

SOS: 

international distress signal in radiotelegraph communications (using Morse code). The signal consists of a sequence: three 

dots – three dashes – three dots.

Beacon: 

the light beam consists of short bright flashes. One flash every 7 seconds. More economical with longer runtime than 

SOS mode. Can be used to attract attention in a critical situation.

FULL stabilization: 

full stabilization of the light output, distinguished by a constant brightness, which does not get reduced due to 

gradual decrease in the battery voltage.

SEMI stabilization: 

semi-stabilization of the light output, distinguished by a reduction of the brightness with the reduction in the 

battery voltage. 

STEP stabilization: 

a stepped stabilization of the light output, distinguished by the lowering of the brightness as the battery 

voltage is reduced, while the driver still enables to fully stabilize the light output at the lower level.

Manufacturer's default presets: 

default settings pre-programmed by the manufacturer - the number of modes for both lines 

of modes, brightness and types of modes etc. The brightness and the type of modes in them are based on which modes are used by 
the customer to solve most of their tasks.

User's preset: 

designed to save your setups in an individual profile. For example, so that after using one of manufacturer's preset, 

you could always return to you individual Custom preset. 

Important notice: Further, when establishing the direction of rotation of the body or the head of the flashlight we assume that the 
flashlight is located right in front of you. With your left handing you are holding its head and its body with your right hand. When 
establishing the direction of rotation (clockwise or not), we are looking at it from the side of the button: rotating clockwise means 
rotating away from us, while counter-clockwise – towards us. Also, we assume that before the start of each operation the 
flashlight has been switched on using the Ordinary Switch-On. For left-handed users the position of the flashlight and the direction 
of actions are mirrored. 

Switching on: 

you can switch on the flashlight in two ways: regular switch-on and tactical switch-on.

Regular switch-on: 

execute a full pressing of the button until the characteristic click. The flashlight will stay switched on until 

switched off by the user or until the battery is discharged.

Tactical switch-on: 

execute an easy pressing of the button. In order for the flashlight to continue shining, the button must be 

held in a pressed position.

Switching off (after a tactical switch-on): 

simply let go of the button.

Switching off (after a regular switch-on): 

execute a full pressing of the button until a characteristic click, then let go of it.

Switching modes: 

in any Line the switching between modes is cyclical. In the order of their sequencing in the flashlight's memory. 

For example, if 3 modes are saved in the memory, then during the transition they will switch on in the following way: 1st, 2nd, 3rd, 
1st etc, cyclically. For First Line, Military Preset: 670lm (#1)  6lm (#2)  108lm (#3), cyclically.

Switching modes in the First Line: 

before starting the switching the flashlight must be in the First Line (the body is screwed in 

to the maximum and is touching the contact ring). Hold the head of the flashlight with your left hand. For switching the mode quickly 
(within 1 second) do the following: turn the body of the flashlight to 1/8..1/4 (of the full turn) counter-clockwise, and then turn the 
body clockwise to the maximum.

Switching modes in the Second Line: 

before starting the switch, the flashlight must be in the Second Line (the body has been 

unscrewed to 1/8..1/4 of the full turn and does not touch the contact ring). Hold the head of the flashlight with your left hand. To 
switch the mode quickly (within 1 second) do the following: turn the body of the flashlight clockwise until the maximum, then turn 
the body to 1/8...1/4 (of the full turn) counter-clockwise.

Switching from the First Line to the Second Line: 

hold the head of the flashlight with your left hand. With your right hand turn the 

body of the flashlight counter-clockwise to 1/8..1/4 of a full turn. About 1 second later the flashlight will switch to the Second Line.

Switching from the Second Line to the First Line: 

hold the head of the flashlight with your left hand. With your right hand 

turn the body of the flashlight clockwise to the maximum. Usually that is 1/8..1/4 of a full turn. About 1 second later the flashlight 
will switch to the First Line.

Protection from an accidental switch-on: 

hold the head and the body of the flashlight with your left hand. With your right 

hand turn the tailcap once counter-clockwise.

Indication of battery voltage: 

depending on which Mode Line you are, perform the actions described below. If you performed 

everything correctly, then during approx. 3 seconds the flashlight will measure the voltage and will show it by blinking. For example, 
3 blinks – short pause – 5 blinks signify a battery voltage of 3.5 Volts. While indication you can switch the modes and the mode 
lines for comparing of the battery voltage for different LED currents.
Important notice: because the energy consumed from the power source depends on the brightness of the mode, then during the 
measurement of the voltage in different modes the voltage showed will differ.

From the mode of the First Line:

 hold the head of the flashlight with your left hand.

1. 

With your right hand turn the body to 1/8..1/4 (of a full turn) counter-clockwise. Wait for the switch to the Second Line 

(approx. 1 second)

2. 

With your right hand turn the body of the flashlight clockwise to the maximum. Wait for the switch to the First Line 

(approx. 1 second)

3. 

Quickly (within 1 second) repeat items 1 and 2, but do not wait for the modes to change.

4. 

Quickly (within 1 second) turn the flashlight off and on.

From the mode of the Second Line:

 hold the head of the flashlight with your left hand.

1. 

With your right hand turn the body of the flashlight clockwise to the maximum. Wait until the switch to the first line 

(approx. 1 second).

2. 

With your right hand turn the body of the flashlight to 1/8..1/4 (of the full turn) counter-clockwise. Wait for the switch  

to the second line (approx. 1 second).

3. 

Quickly (within 1 second) repeat items 1 and 2, but do not wait for the mode lines to change.

4. 

Quickly (within 1 second) turn the flashlight off and on.
