Boot-up Battery Level Indication
Each time the light is turned on, the battery level indicator will automatically display the battery status for 3 seconds. Green constant on: saturated Green flashes: sufficient Red constant on: poor Red flashes: critical Note: This only works on rechargeable LI-ion 18650 battery.
Battery Replacement
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then screw the tail cap back on.
Low-voltage Warning
When the voltage level drops below 3V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator will display red and the flashlight blinks every three seconds to remind you to replace the battery. To ensure normal use, the flashlight will work until the battery runs out or the battery over-discharging protection activates.
Note: This only works on rechargeable LI-ion 18650 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 Protection
The light will accumulate a lot of heat when it is working at Turbo mode. When the light is overheated up to 65°C or above, the flashlight will automatically step down a few lumens to reduce the temperature; when the temperature is lower than 65°C, the output will gradually return to Turbo output level.
