Built-in rechargeability and improved performance are what make the Fenix E35R flashlight unique from its predecessor, the Fenix E35 V3.0. This small flashlight, which is only 4.72 inches long, is able to blast a maximum 3100 lumens 853 feet (260m)—amazing for a flashlight this size! The single side switch activates on/off and all lighting modes—no need for a tail switch. A magnet now sits where a tail switch normally would, allowing you to attach the flashlight to most metal surfaces for hands-free use. It’s USB-C rechargeable with a battery level indicator and is waterproof and dustproof. When you need a rechargeable super bright EDC flashlight, the Fenix E35R is the perfect choice.

Green light flashes: sufficient 85% – 50%
Red light on: poor 50% – 25%
Red light flashes: critical 25% – 1%
Note: This only works with Fenix ARB-L21 series rechargeable battery.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used on High or Turbo 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 the reselection of High or Turbo modes.
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco mode is reached. When this happens in Eco mode, the battery level indicator constantly blinks red to remind you to timely recharge or replace the battery.
Note: This only works with Fenix ARB-L21 series rechargeable battery.
