Usage and Maintenance

Great light with significant upgrades from v2

Really great upgrades from v2. Love the new memory feature and the magnetic tail adds a lot of functionality to this light. I love the little lines cut around the metal tail switch. I do miss the lines around the body in v2. While the new smooth body is easier to slide into a pocket it also makes it more slippery and also work its way out of your pocket. The new optic is nice and the smoother transition in the spot and spill is nice. But I really loved the gem like optic of v2. I think anyone who are familiar with modern flashlights will love this one. The unfortunate thing is the new features also moves this light out of the flashlight muggle territory and into the enthusiast territory. I’ve bought the v2 steadily since its inception due to its muggle friendly simple UI. Although most people I’ve given it to assume it’s a very expensive Duracell flashlight due to its copper bezel and gem like reflector. I bought 3 of these v3’s and the 2 people I attempted to give it to told me it was broken due to their inability to understand how memory mode works on these. In conclusion great light with great upgrades for all flashlight enthusiasts but not recommended for the average person who is unfamiliar with modern flashlights and their UI. Hopefully Fenix will continue to make the V2 for all the flashlight muggles I come across.


I’m very disappointed in this flashlight. The beam is YELLOW, rather than white.
I would not recommend this product to anyone.
