Q6. Why does the TK35UE V2.0 downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: There are two reasons:

1. Intelligent Overheat Protection

The light will accumulate a lot of heat when used at relatively high modes for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user to reselect the modes.

2. Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output, the battery level indicator constantly blinks red to remind you to recharge or replace the battery.

A: The reasons that may cause the light to flicker, shine intermittently or even fail to illuminate:

1. Poor battery level.

Solution: Recharge or replace the battery.

2. The contact or contact point of the battery or flashlight is dirty.  

Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

3. The battery protection board is in a protective state and unable to be released.

Solution: Take out the battery and reload them.

4. A single 18650 battery fails to activate Turbo mode.

Solution: Take out and reload the battery, replace a new battery or use two batteries.
