Usage and Maintenance 

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using only a high-quality protected battery.
  • If the light will not be used for an extended period, remove the battery for proper storage.
  • Lock the light or remove the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the light's performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons: 
    A: Poor battery level. 
    Solution: Recharge battery. 
    B: The contact or contact point of the battery or flashlight is dirty.

If the above methods don't work, please contact your authorized distributor.

Fenix c7 is the best light I will get I love it and it’s really bright to use it for security thank you Fenix lighting for making better lights and flashlights

david teltschik
Bright, versatile and portable. Love it!

Moved from my old trusty Maglite to the C7. What a difference! I didn’t realize how sim my old Maglite was until I turned on the C7. Plenty of range in lighting options. It can handle nearfield work and crazy distance with the extreme brightness. It does get quite hot up front when on max power so be careful.

Excellent light

I bought this for my husband and he loves how bright it is. Easy to handle and very durable. It is well worth the money

Rikk Rohl
Excellent purchase

Needed a small, durable flashlight that still provided for high luminosity, as I am a power generator technician. Fit the bill perfectly, and the magnetic butt has come in handy a few times.
