Introduction#
The Armytek Wizard C2 WG Warm Headlamp has two warm white emitters and two green emitters behind a single pebble TIR optic.
I have previously reviewed the red version of this headlamp. I really like the wide and smooth beam that it produces.
I also like how the user interface has the same shortcuts and modes for both white and red lights.
When Armytek reached out, I asked if I could review the green version too!
Armytek kindly provided this headlamp for review. I have not been paid for this review nor have I held back my opinions of this torch.
Packaging#
The headlamp comes in a gray and green box with Armytek branding. There are specifications on the box.
The following was included in the box:
- Armytek Wizard C2 WG (Warm Light) headlamp.
- Headband.
- Armytek 18650 3200mAh cell.
- USB-A to magnetic charging cable.
- Pocket clip.
- Two spare o-rings.
- User manual.
User Manual#
The PDF version of the user manual online has much more information.
Torch in use#
The headband for the Armytek Wizard C2 WG headlamp is very comfortable and it fits my large head.
I have been using this torch as a floodlight for my bicycle for a few months now. The green light looks cool but I prefer to use the warm white light.
The white and green emitters can be controlled with a single button.
The torch can tailstand and it can be carried as a right-angle torch with a pocket clip.
The magnet in the tailcap is strong. This allows the headlamp to be used as a work light.
Build quality#
The Armytek Wizard C2 WG is made of aluminium and it has a matte black anodised finish. It feels smooth. There are no sharp edges.
The torch clicks into the mount of the headband and a ring can be used to make it even more secure.
I personally find this headband to be very comfortable.
The button feels firm and it gives a satisfying click.
The threads came well lubricated but they will get dirty over time because they are unanodised.
There are two o-rings to help improve water resistance.
Springs at the tail and the head of the torch allow flat top 18650 cells to fit.
LED, bezel, lens, reflector and beam#
The Armytek Wizard C2 WG has two warm white and two green emitters.
The TIR optic has a 120 degree beam angle.
A stainless steel bezel has been press fit onto a pebble TIR optic.
CCT, CRI, and duv#
I have taken Correlated Colour Temperature (CCT) and Colour Rendering Index (CRI, RA of R1-R8) measurements with the torch positioned one metre away from an Opple Light Master Pro III (G3).
The CCT is around 3880K, the CRI is around 68, and the Delta u, v is slighty positive (green).
The beam produced is very floody. It has a smooth hot spot. I really like the warm tint!
| LED | Mode | CCT (K) | CRI (Ra) | x | y | Duv |
|---|---|---|---|---|---|---|
| White | Main1 | 3814 | 68.5 | 0.3937 | 0.3967 | 0.0054 |
| White | Main2 | 3839 | 68.5 | 0.3919 | 0.3941 | 0.0047 |
| White | Turbo | 4000 | 68.2 | 0.3832 | 0.3864 | 0.0037 |

User interface#
The headlamp has a single switch to control the white and green emitters.
There are three levels in the main group: Main1, Main2 and Turbo.
| State | Action | Result |
|---|---|---|
| Any | Two clicks | Change between white and green emitters |
| Off | Click | On (mode memory) |
| Off | Press and hold | On (firefly) |
| On | Click | Off |
| On | Press and hold | Cycle (Main1, Main2, Turbo) |
| Firefly | Press and hold | Cycle (Main1, Main2, Turbo) |
The last used mode for white or green is memorised when turning the headlamp off or when changing between white and green emitters.
Strobe#
1 Hz strobe in green or white.
Strobe can be added or removed from the main cycle group:
- Press and hold the button to turn the light on and cycle through the main group;
- Unscrew the tailcap 1/4 turn and screw it back on to temporarily turn the headlamp off;
- Continue to hold the button and observe whether Strobe has been added or removed while the main group cycles.
White Light: Strobe
Green Light: Strobe
I measured Strobe with a Zoyi ZT-703S oscilloscope using High Speed mode.
Lock out#
There is no electronic lock out mode. The tailcap can be turned 1/4 to physically lock out the headlamp.
Low voltage protection#
There is low voltage protection.
The torch turns off around 2.65V.
I tested low voltage protection by connecting the driver of the torch to a bench power supply and then by lowering the voltage from 4.2V to 0V.
PWM#
I did not notice any visible PWM (flickering).
I measured the PWM of the light with a Zoyi ZT-703S oscilloscope.

Green Light (Firefly, Main1, Main2, Turbo)
What I like about the UI#
- Shortcut to Firefly from off.
- Simple to use.
What could be improved#
- A shortcut to Turbo from off would be nice.
- A Low mode with about 20 to 50 lumens would be nice.
- Adding and removing Strobe from the main group is a bit difficult.
Batteries and charging#
Battery#
An Armytek 18650 3.7V Li-ion 3200mAh cell was included. It arrived with a voltage of 3.20V.
I tried the following cells:
| Cell | Top | Compatible? |
|---|---|---|
| Armytek 18650 3.7V Li-ion 3200mAh | Flat | Yes |
| Samsung 30Q 18650 3.7V Li-ion 3000mAh | Flat | Yes |
| Protected 18650 3.7V Li-ion 2600mAh | Button | Yes |
Charging#
Power supply: PinePower Desktop USB-C
USB Meter: ChargerLAB Power-Z KM003C
Room temperature: 21 C
The tailcap needs to be unscrewed slighty (1/4th of a turn) and then the magnetic charging cable needs to be attached to the tailcap to start charging the cell inside the headlamp.
Charging status indicator#
The battery took 3 hours 30 minutes to charge from 3.00V to 4.15V at a rate of 5V 1.2A.
The charging indicator in the magnetic charger is red while charging and it becomes green when charging is complete.
When the charger is connected:
| Colour | Status |
|---|---|
| Green blinking | Evaluation of battery voltage. |
| Red blinking | Unscrew the tailcap to 1/4 for charging. |
| Orange blinking | USB power source voltage is too low for correct continuation of charging or bad contact between charger and battery. Clean the tailcap and the threads of the flashlight parts, use a different power source. |
| Red | Charging with rated charging current is going on. |
| Orange | USB power source voltage is too low, charging current may be reduced. |
| Green | Charging is finished. |
Power supply compatibility#
I tried the following power supplies with the USB-A magnetic charging cable:
| Power supply | USB Type | Protocol | Does it charge? |
|---|---|---|---|
| PinePower Desktop | USB-A | QC | Yes |
| PinePower Desktop | USB-A | Yes |

I tested the torch using the included cell.
Lumen measurements#
I used a bench power supply to measure the current at turn on for most modes. I used a UNI-T UT139C Digital Multimeter to measure the current at turn on for Firefly modes.
| LED | Mode | Amps at start | Specs | Lumens @turn on | Lumens @30 sec | Lumens @10 min |
|---|---|---|---|---|---|---|
| Green | Firefly | 6 mA | 0.2 | |||
| Green | Main1 | 0.08 A | 36 | 46 | 46 | 46 |
| Green | Main2 | 0.31 A | 140 | 127 | 125 | 122 |
| Green | Turbo | 2.00 A | 400 + 270 | 387 | 371 | 236 |
| White | Firefly | 5 mA | 0.5 | |||
| White | Main1 | 0.22 A | 120 | 124 | 120 | 119 |
| White | Main2 | 0.80 A | 380 | 395 | 386 | 373 |
| White | Turbo | 4.10 A | 1,020 + 480 | 1,300 | 1,049 | 482 |
Firefly was too low for my DIY lumen tube to detect.
Standby drain#
13.5 µA.
Runtime graphs#
I used my own DIY lumen tube with a TSL2591 sensor and forked bmengineer’s project RuTiTe to record runtimes.
Note: Lumen measurements may be off by 10% with my DIY lumen tube.
The room temperature was approximately 22 C.
Runtime#
Here is a summary of the runtime results:
| LED | Mode | User manual | Runtime | Turn off | Final voltage |
|---|---|---|---|---|---|
| White | Turbo | 90s + 2h 30min | 2h 30min 36s | 2h 48min 14s+ | 3.00 |
| White | Main2 | 4h | 3h 48min 37s | 3h 48min 37s+ | 3.05 |
| White | Main1 | 13h | 11h 51min 12s | 11h 51min 12s+ | 3.04 |
| Green | Turbo | 6min + 2h 20min | 3h 10min 48s | 3h 10min 48s+ | 3.00 |
| Green | Main2 | 10h | 8h 40min 26s | 8h 40min 26s+ | 2.95 |
| Green | Main1 | 35h | 10min+ | 10min+ |
“Runtime” is the time until the output reduces to 10% of the output at 30 seconds (as per the ANSI/PLATO FL1 2019 Standard).
“Turn off” is the time until my DIY lumen tube no longer detects more than 1 lumen.
“+” indicates that the light remained on after recording had stopped.
Turbo dropped to less than 1 lumen after 2 hours 48 minutes 14 seconds and it was still on after 6 hours.
I stopped recording after 10 minutes for the Green Main1 mode.
The runtimes for Turbo modes was slightly better than expected.
Main2 for white and green and Main1 for white fell slightly short of the expected runtimes.
Overall, the output is well regulated and you may get longer runtimes with a higher capacity cell. The included cell has a capacity of 3200mAh. These days you can find 18650 cells with a capacity of 4000mAh.
Throw#
I took lux measurements with a UNI-T UT383BT at 30 seconds. Turbo was measured at five metres.
| LED | Mode | Specs (cd) | Specs (m) | Candela measured (cd) | Distance (m) |
|---|---|---|---|---|---|
| Green | Turbo | 1,000 | 63 | 1,475 | 76 |
| White | Turbo | 2,400 | 97 | 3,700 | 121 |
Beamshots#
I went to a local park and aimed the Armytek Wizard C2 WG at a tree 70 metres away while using Turbo.
Beamshots were taken using a Sony RX100M2 using 3.2", f3.2, ISO 100, 5000K WB.

Conclusion#
The Armytek Wizard C2 WG (Warm Light) is a pretty good headlamp with white and green lights.
I like the 3880K colour temperature and the tint of the floody beam. The CRI is a little low at 68.
The headband is comfortable to wear and the design of the mount makes it easier to take the headlamp out and put it back in.
Magnetic charging is pretty convenient. But I find it annoying that the tailcap needs to be unscrewed a 1/4 turn to allow the magnetic charger to work. With other magnetic charging systems, you can just connect the magnetic charger and it starts charging.
It is nice to see 5 modes (Firefly, Main1, Main2, Turbo, Strobe) for the green emitters in this headlamp.
I think that the white emitters need an extra Low mode of 20 to 50 lumens. There is a big jump from Firefly (0.5 lumens) to Main1 (120 lumens).
The light output is well regulated. The runtimes could be even better if Armytek included an 18650 cell with a 4000mAh capacity instead of 3200mAh.
I can highly recommend this headlamp and the red version of this headlamp.
Pros:#
- Nice floody beam.
- Output is well regulated.
- Comfortable headband.
- Magnetic charging.
- Multiple Green output levels.
Cons:#
- Low CRI.
- Missing a Low (10 lumen) mode for the white light.
- Unscrew tailcap 1/4 turn to charge.
