Usage and Maintenance

  • Disassembling the sealed adjustable angle flashlight head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality AA battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • 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 lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons: 
    A: The battery needs replacing. 
    Solution: Replace battery pack /battery (Ensure battery is inserted according to the manufacturer’s specifications). 
    B: The threads, PCB board contact or other contacts are dirty. 
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

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



This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone’s eyes.

Very nice light

Lane Westra
Good. Clip fits my vest straps. Im a little concerned about exposure to climates, or clip retention.

Seems great so far. We’ll see if it holds up. I like that you can recharge or put in AA’s. Thats the best feature.

Small, Strong, a Bit Heavy

I got this to replace the AMAZING MC11. I mostly drop it in my pack when I travel. Good to have a light if you are in strange place and the power goes out. I very much like the small size the the adjustable head, but on the other hand it would be better if it was half the weight.

Poor Quality , Poor customer support Don't expect a warranty

New out of box only right bulb worked. After some arm twisting I got a replacement. This time it was the left bulb not working out of the box. I ended up keeping both lights as Customer service was just not interested in my return business.
Both flash lights were completely useless in less than 1 year.

Hi AJ - our records show that one of our warranty team members had gotten back to you about this warranty claim back in April 2020 and we never heard back from you. You are welcome to reach out to them again if you would like to follow up on this warranty claim.

Timothy Colvin

Very well made and the angle head is great. I wish you made it in a larger size.

Gary Swiger

Great light, but wish it was made of mostly aluminum.
