The Fenix C7 V2.0 is a high-performance rechargeable flashlight offering an output of up to 3300 lumens (ANSI) and a beam distance of up to 575 meters. Excellent performance has been achieved by using a modern Luminus SFT-70 Gen2 LED. Power is supplied by a high-capacity Li-ion 21700 battery with a capacity of 5000 mAh (included), which is charged directly inside the flashlight via a modern, waterproof inner USB-C port. The flashlight was designed with ease of use and wide versatility in mind. Seven lighting modes allow you to choose between high output and a long runtime of up to 79 hours. A blinding Strobe and an SOS signal are also available for emergency situations. The Fenix C7 V2.0 is powered by a digitally regulated constant current to guarantee stable light output even as battery voltage drops (during gradual discharging). Turning it on and switching modes is very simple and is done with a side-mounted ergonomic switch. The tail of the flashlight is magnetic, making it easy to attach to any iron surface. The flashlight is an ideal lighting tool with an excellent ratio of high performance, quality, and price. Due to its versatility, it is highly recommended for industrial work, home workshops, and as an ideal outdoor partner for hiking and various sports activities.

All flashlight parameters (luminous flux, battery runtime, waterproofing, beam distance, and impact resistance) are measured in accordance with the ANSI/NEMA FL 1-2009 standard.

Operating Instructions for the Fenix C7 V2.0

There may be an insulation cap on the battery inside the flashlight from the factory. Remove it from the battery before first use. To turn the light on or off, press and hold the side switch for about 0.5 seconds. You can cycle through the 30 - 100 - 400 - 1400 - 3300 lumen output modes at any time during operation by single-clicking the side switch. Enter Strobe by pressing the switch for 1.2 seconds (even from an off state), then a single click of the switch toggles between Strobe and SOS modes.

Charging - open the anti-dust cover of the charging port on the side of the flashlight and plug in the included cable (USB-C connector); plug the other end of the cable into a computer, or a USB wall or car adapter. The indicator LED displays red while charging. When fully charged, it will turn green. Charging a fully depleted battery takes approximately 3 hours (with a 5 V / 2 A charging adapter). The flashlight can be operated while charging.

Intelligent Overheat Protection - if the flashlight temperature exceeds 60 °C, it will automatically step down the output in gradual increments. Once the temperature drops below 60 °C, the output will gradually increase again.

Battery Level Indication - with a short press of the switch (the flashlight must be off) or upon turning the flashlight on, the LED indicator in the switch activates for 3 seconds. If the indicator diode shows solid green, the battery is 85–100% saturated. Flashing green indicates 50–85% capacity. Solid red means it is 25–50% charged. Flashing red indicates critical power with less than 25% battery capacity remaining.

Locking the Switch - to prevent accidental activation in your luggage, double click the switch quickly within 0.5 seconds (the flashlight must be off). The flashlight will blink twice in low mode to indicate locked status. If you attempt to turn on the locked flashlight, it will only blink twice. Unlock by double-clicking the switch quickly again; the flashlight will simultaneously turn on in the lowest mode. Accidental activation can also be prevented by slightly unscrewing the tail cap of the flashlight.

Low-voltage Warning - the flashlight is programmed to downshift gradually to the lowest brightness level. When the voltage level drops below 3.0 V, the side switch begins to blink red rapidly and the main light blinks for 20 seconds to remind you to recharge or replace the battery. The blinking of the main light can be stopped by single-clicking the switch. After this, the flashlight can still be used in the lowest mode (Eco) for over 30 minutes.

Warnings

• Do not disassemble the sealed head of the flashlight yourself, as doing so will void the warranty.
• Do NOT shine this flashlight onto flammable objects at close range to avoid damaging them or creating a hazard due to high temperatures!
• Lock the flashlight, take out the battery, or unscrew the tail cap to prevent accidental activation when the flashlight is placed in a closed and flammable environment such as pockets and backpacks!
• Use only high-quality 21700 Li-ion batteries to prevent damage to the flashlight from, for example, battery leakage.
• If the protective O-rings appear damaged after prolonged use, replace them. The rings also need to be lubricated to prevent rubber wear. By following these rules, the flashlight will be properly protected against water.
• If the flashlight flickers, does not switch to a higher mode, or fails to illuminate, it may be due to one of the following reasons:
  • The battery is depleted; recharge or replace it.
  • The contacts inside the flashlight are dirty – clean them with a cotton swab soaked in rubbing alcohol.
  • The flashlight body is loose; tighten it.
