NOTICE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1 using four 1.2V 2450mAh Ni-MH batteries under laboratory conditions. The data may vary slightly during real-world use due to battery type, individual usage habits and environmental factors.
* The runtime for Turbo and High mode are the testing result before starting temperature regulation.
Operating Instruction
Assembling headband
- Attach the under headband to the headlamp as illustrated in diagram (1) by first sliding the band down to the bottom of the slot, and then hooking the top edge under the top slot as shown in diagram (2). And attach the under headband by first sliding the band down to the battery case as the same way indicated above.

On/Off
Turn On: When the light is off, press and hold the headlamp switch for 0.5 second, and the headlamp will enter the previously used mode. Turn off: When the light is on, press and hold the headlamp switch to turn the light off. Direct access to the ultralow mode: When the light is off, tap the headlamp switch to enter ultralow mode. Direct access to the turbo mode: When the light is off, press and hold the headlamp switch for 1.5 seconds to enter Turbo (1000lumens).
Changing Brightness levels
When the light is on, tap the headlamp switch repeatedly to cycle through "Ultralow- Low-Mid-High-Turbo". (The HA40 memorizes its previously used brightness level. When the light is turned off, hold and press the switch for 0.5 second, and it will return to the previously used brightness level)
Accessing Special modes (Caution Light/SOS/ Beacon)
When the light is off, quickly tap the headlamp switch twice to turn on the caution light. After the caution light is turned on, tap the switch repeatedly to cycle through "SOS-Beacon-Caution Light". Press and hold the switch to exit. (Special modes cannot be memorized)
ATR (Advanced Temperature Regulation)
With Advanced Temperature Regulation module, the HA40 regulates its output and adapts to the ambient environment, maintaining optimal performance.
Changing Batteries
Change the batteries when the output appears to be dim, or the Turbo and High modes can no longer be accessed.
