NOTE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 1xIMR 18650 battery (3100mAh) under laboratory conditions.
- The data may vary in real-world use due to different battery use or environmental conditions. The runtime for Turbo or High mode is the testing result before starting temperature
regulation - The Turbo 1800 lumens requires the use of rechargeable IMR18650 or 18650 Li-ion
batteries with output current higher than 8A. The Turbo is not accessible with CR123A or RCR123A batteries.

Battery Installation
As illustrated, insert batteries with the positive (+) end facing towards the head.
Warning
- . Ensure batteries are inserted with the positive (+) end pointing to the head. The HC33 will not operate with incorrectly inserted batteries.
- CAUTION! Possible dangerous radiation! Don’t look into the light! Maybe dangerous for your eyes.
- When the power level of IMR18650 Li-ion battery is low, please stop using and recharge the battery.
- When the HC33 is kept in a backpack, please loosen the tailcap to prevent accidental activation of the flashlight; When the HC33 is left unused for extended periods of time, please remove all batteries to prevent battery leakage.
- Do not submerge the product in water or any liquid when it has generated sufficient heat, doing so will cause pressure inequalities and significantly increase risk of water damages.
- The product contains strong magnetic components. DO NOT put it close to objects that tend to suffer from magnetic interference (e.g. bank cards, watches and medical equipment).
- ON/OFF
Turn on: When the light is off, press the switch for 0.6 seconds to turn on the light. Turn off: When the light is on, press the switch for 0.6 seconds to turn off the light Instant Ultralow: With the HC33 is switched off, tap the switch to enter ultralow mode. Instant Turbo: With the HC33 is switched off, press the switch for about 1.5 seconds to enter turbo mode. - Adjusting Brightness Levels
With the HC33 is switched on, press the switch repeatedly to cycle through brightness levels of Ultralow-LowMiddle-High-Turbo. (Brightness levels can be memorized) - Special modes (Strobe/SOS/Beacon)
When the light is off, quickly tap the headlamp switch twice to enter Strobe. After Strobe is turned on, tap the switch repeatedly to cycle through SOS-Beacon-Strobe. Turn off the light to exit. (Special modes can not be memorized) - ATR (Advanced Temperature Regulation)
With Advanced Temperature Regulation module, the HC33 regulates its output and adapts to the ambient environment, maintaining optimal performance. - Power Tips
When power is off, every time the battery is installed, tighten the head and tail cap, the light will report battery voltage (to the nearest ±0.1V) For example, when the battery voltage is at a maximum charge of 4.2V, the power indicator will blink 4 times, followed by 1.5 seconds pause and 2 more blinks before entering the standby status. Different voltages represent the corresponding remaining battery power levels:
1×18650 battery:
Low power 3.5V
Note:- when using two CR123/RCR123 in series, the flashlight only reports the average voltage of the two batteries.
- If it can not report the voltage normally, please loosen the tail cap first, then press the switch for 1 second to ensure the HC33 is power off thoroughly and then tighten the tail cap.
- Changing Batteries
Recharge the batteries when the output appears to be dim or the brightness levels can not be selected normally. - Maintenance Every 6 months, wipe the threads of the battery case with a clean cloth followed by applying a thin coating of silicon-based lubricant.
