The flashlight comes in a nice cardboard box.
The following accessories are included in the box:
- Headband.
- Micro-USB charging cable.
- Pocket clip.
- 1 x 18650 battery.
- 2 x replacement o-rings.
- User manual.
The Armytek is a headlamp/EDC flashlight hybrid.
It comes with a flat black anodization on its body, along with the familiar chalky finish that Armytek uses.
The Elf C2 is operated via an e-switch mounted on the rear of the head.
The upper part of the head is completely flat.
The head houses the TIR emitter along with a Samsung LH351D emitter.
The assembly is held in place via a metal ring that seems to be screwed and glued into place.
The TIR selected by the manufacturer is used in order to provide a wide, even beam.
Opposite to the e-switch one finds the charging interface.
The charging port is sealed via a rubber flap.
The charging interface of the flashlight is using a normal microUSB port.
The head is glued to the body of the flashlight.
The rear threads arrived very nicely lubricated and are anodized, which allows the flashlight to get mechanically locked out.
Looking into the tail we can see a thick spring and its PCB.
The tail piece is completely flat.
A strong magnet is also part of the tail and can easily support the weight of the flashlight.
As already said, a metal pocket clip is also included in the flashlight's bundle.
The pocket clip can be installed both ways and provide great retention while maintaining a low profile.
As with all Armytek flashlights, the Elf C2 also comes with an Armytek branded 18650 battery.
The battery is marked with 3200mAh of capacity and is flat top.
Of course, the Elf C2 being advertised as a headlamp, also comes with a great 3-piece headband.
The headband is elastic and its length is fully adjustable.
The flashlight is installed into the plastic mount.
The mount provides adequate grip to keep the Elf C2 in place, but for security's sake the manufacturer also utilizes a thick overlapping o-ring.
The open-ended mount allows the headlight to be easily operated.
User Interface
Here's all the supported actions by the flashlight's firmware.
Turn on/off: Single press.
Mode cycle: Long press (Medium1 > Medium2 > Medium3).
Turbo: Double press.
Firefly: Long press while off. Keeping the button press will initiate a mode cycle (Firefly1 > Firefly2 > Medium1 > Medium 2 > Medium3).
As you can tell, the flashlight's firmware is pretty straightforward.
Mode memory is present (including when in Turbo).
Low Voltage Warning and Low Voltage Protection are also present.
Output
Here's my output measurements along with the power draw on each output mode.
As we can see, the Armytek Elf C2 is able to push almost 1100 lumen on Turbo.
The manufacturer's max output claims are very accurate.
Thermal Regulation
Here's a thermal regulation graph I created for the Armytek Elf C2.
What we can see in the graph:
- Turbo maintains its full output for 4 minutes.
- Past the 4 minute mark, Turbo will slowly step down to 600 lumen over a 15 min time window.
- Medium3, Medium2 (and all of the other modes) are fully regulated and sustainable for the whole span of the test.
