Usage and Maintenance of the E12 V2.0 AA Flashlight

  • Disassembling the sealed head can cause damage to the light and will void the warranty.

Great light

Would but again

Evan Watson
Worked great for just over two years and then died

Worked great right up to the time I pushed the button annnd nothing. Wouldn’t recommend for critical applications……

Assuming this had a fresh battery in it when it suddenly stopped working, have you reached out to our warranty team? They will need the 11 digit alphanumeric serial number from the light and can direct you to the correct service center. 888-775-9996 ext 1, warranty@fenixlighting.com

Great light for the price!

If you’re looking for a bright small size light E12 is a good all around light. 3 different intensities, lightweight, compact, it has a 2 way belt/pocket clip that holds the light very securely. I was fortunate to get them when on sale so I brought 2. Definitely recommend.

Some Flashlight User
Waterproof rating did not disappoint

Shipping was fast and had no surprises. The flashlight itself met expectation. Most of all, it went through an inadvertent laundry cycle without damage -- the battery was drained, perhaps from the bumps in the wash and dry cycle, but the flashlight works just fine with a fresh battery. Pretty effective waterproofing I'd say.

Jon Luke
Little but super bright

Bought this on a recommendation from a coworker I seen using this tiny light. So glad I did. It is now in my pocket every day and I barely notice it! Works good

Jonathan Soneff
Great little light

I use these at work for product inspections. I use them on hikes at night for 90% of the lighting needs. I also carry a much brighter Fenix Lite when I need to see a large area, or if there is a potential threat, animal, or otherwise.

These are reliable and take care of. Most of my flashlight needs I a handful of them, and I’ve given as many away.
