1. Output ranges from 100 lumens to 9000 lumens.
2. Single click the switch , for each single clicking, the output will increase 100 lumens. Press switch over 0.5 seconds, then the output will increase 1000 lumens for each pressing.
3. Single click the switch , for each single clicking, the output will decrease 100 lumens. Press switch over 0.5 seconds, then the output will decrease 1000 lumens for each pressing.

Strobe

In any status, press and hold the switch over 1.2 seconds to enter strobe, click once again to return to the last used brightness.

Instant Turbo

With the light switched on, single click the switch to enter Turbo, click once again to return to the last used brightness.

Charging And Power Bank Function

Charging: Plug the USB side of the charging cable into the any USB power supply, uncover the anti-dust cap of the light. And plug the Micro USB side of the charging cable into the charging port of the light. When charging the OLED screen will display charging icon, and current battery level will be displayed. The normal charging time is about 6 hours.

Power bank function: Plug the USB side of any digital device into the USB side of the light. Then the light will display discharging icon when discharging begins. The max discharging current is 2A.

Note:

1. The light can be turned on when it is in charging and discharging status, but only 100 lumens output can be reached.
2. Once charging is completed, be sure to remove the charging cable and replace the anti-dust cap to protect from dust and foreign objects.
3. Recharge a stored light every four months to maintain optimum performance of the battery.

Intelligent Memory Circuit

The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.

Intelligent Overheat Protection

The light will accumulate a lot of heat when it is working at high output levels. When the light is overheated up to 65 ℃ or above, the output will be automatically downshifted by the step of 1000 lumens until 2500 lumens is reached to reduce the temperature. High output levels can be reselected by pressing switch when the temperature is lowered than 65 ℃.

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift by the step of 1000 lumens until 100 lumens is reached. Until the battery protection circuit activates to turn off the flashlight.

Battery Specifications

The standardly configured battery is ARB-L45-14000 (7.2V/7000mAh), Fenix batteries with the same type can be used.

Battery Replacement
