Optical Features
1. The reflector of the ArmyTek Viking S G109.11 flashlight has been modeled and calculated in computer software for the design of optical systems that enabled to produce a flawless light beam for a distance more than 200 meters.
2. Ultra-transparent and tempered glass was used with anti-reflective and lens coating, normally used in photo equipment only.
3. The transparency of the glass is 98-99%.
4. The angle of the light spot is 5 degrees (depending on the modification).
5. The angle of the light spill is 36 degrees.
6. At the distance of 300 feet (92 meters), the diameter of the light spot is 8 meters.
Electrical Features
The flashlight has been designed on the basis of the new-generation electronic driver with STEP runtime technology.
1. Advanced electronic protection from incorrect battery installation, without reducing the efficiency of the driver
2. Smooth light output. Important notice: no irritating flicker effects.
3. Ecological algorithm of the stabilization control, which decreases the system power consumption, making the flashlight very effective.
4. Capability with unprotected 18650 Li-Ion batteries.
Ergonomic Features
1. Removable clip, functional and easy to use.
2. The ability to use batteries with a flat contact.
3. Grip for firm holding.
4. Protection from switching on accidentally (special turn of the tailcap).
5. 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 coating 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 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.
Main definitions
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.
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 Orings 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: one maximal mode 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 3 modes is available when the contact ring does not touch the end of the body of the flashlight (no electrical contact).
Easy Operation
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 the First Line: in First Line simply switch on the flashlight for maximal mode.
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). To switch the mode quickly (within 1 second) simply switch off and on the flashlight during 1 second.
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.
