[Review] Armytek Partner C1 Pro ( XP-L , 1 x 18350 ) - Testing output and regulation, Outdoor beamshots

The flashlight was sent to me by Armytek for review.
Here's the product's link: Armytek Partner C1 Pro

The Partner C1 Pro comes in a simple cardboard box.
The package includes an adjustable wrist strap, a pocket clip, two replacement o-rings and an extra tail switch cap.

Additionally, there's a nylon holster included.
The holster is utilizing a belt-loop while it's secured using velcro.


The flashlight comes with matte black anodization and is e-switch operated.
It's worth noting that Armytek's anodization is probably my favorite. It's matte, chalky and provides excellent grip.
If you have handled an Armytek before, you are probably familiar with what I am talking about.

Opposite to the e-switch there is an anti-roll cutout.

Being advertised as a tactical flashlight, it's using a dual switch setup.
The rear switch is mechanical and forward clicky, which means that it can also be activated momentarily.

The side switch is electronic and is purely used to control the modes.
Inside it there is an indicator LED that shines every 5 secs (while turned on) to indicate the battery's level.

The Partner C1 Pro is using an XP-L HD emitter and a TIR optic.
The emitter setup is protected by a polished, tactical bezel.

The tail threads are square cut and anodized, which allows the user to mechanically lock out the flashlight.
As with all Armytek flashlights, the threads arrived very well lubricated and they use dual o-rings.

The tail is using a stiff spring which is held down by an aluminum retaining ring.

After taking apart the switch, it can be seen that the rear button boot is also kept is place by a buttseparate retainer.
That way Armytek can guarantee full waterproofness - the flashlight is rated as IP68!

The head threads are also square cut and well lubricated.
Again a dual o-ring setup for maximum sealing is used.

The positive contact of the driver is using spring.
The pads are probably used for programming / testing the driver.

User Interface

The Partner C1 Pro comes with a very nice and easy UI.
Here's all the supported actions (whenever no switch is specific, I am referring to the side e-switch):

Turn on/off: Single press (rear switch).
Momentary on: Half press (rear switch).
Mode cycle: Singe press (Firefly > Main1 > Main2 > Main3 > Turbo > Firefly > ...)
Strobe: Long press
Strobe cycle: Long press while in strobe ( Strobe1 > Strobe2)

LPV kicks in at 2.8v.
Mode memory is active.

Output and Regulation

In order to get my output readings I used a Vapcell 18350 1100mAh cell, while for the regulation graphs I used the RD DPS5020 bench power supply.
Here's the output I measured along with the respective current draw:

My readings seem to be matching the manufacturer's claim for 650 OTF lumens.

Here's a Voltage / Amperage graph:

And the respective Volts / Power graph:


What we can see from the graphs:

  • Turbo is not regulated, as the input voltage affects the current draw
  • Turbo drops to Main2 at 3V
  • Main3 is regulated down to 3.1 V
  • Main2 is regulated down to 3V
  • Main1 (and Firefly, which is now shown) are fully regulated
  • LVP is set at 2.8V

And finally a Thermal Regulation ( Output / Time ) graph for Turbo.

As predicted, Turbo's output wasn't going to be constant.
Using a Vapcell 18350(1100mAh) I got 75 mins of runtime in Turbo.


At 12m

At 25m

At 35m

Things I liked:

  • Built like a tank.
  • IP68 rated.
  • All modes except turbo are regulated.
  • The heat produced in Turbo is sustainable with no problems.
  • Easy to remember UI .

Things 'd like to be improved:

  • A constant current Turbo would be perfect.
  • Allow the user to turn on/off memory.
