    I work construction and this is my EDC. Carry it in a holster and like the compact size. The level of light output is crazy, close to the 18650 lights. When i need it to perform it never fails, and has helped me get jobs done in tight dark places. Tail cap switch and side switch are a great combo. Only drawback is the battery life is a little short on high. For a EDC, this is the one.

    Take it from a guy who’s hard on his gear: this is the EDC light you need. I have the original (~120 lumen max), for 4 years now. I take it wade-fishing in salt-water, hunting, EDC/365 in my profession as a military engineer and it’s never let me down. I’m constantly in dark mechanical rooms, getting calls for late night hazmat spills, etc – this light goes with me everywhere. The combination of super-dim to super-bright, rock solid waterproofing, unbreakable/droppable design and the convenience of AA batteries and a reversible belt clip for hat-brim attachment makes it simply a do-everything light. I have brighter lights and more expensive lights, but this is the one light that’ll do everything and comes everywhere with me. I’m so sold that I buy this light as a departing gift for my junior officers in my command.

    Is says 350 lum max. 😮 I get a lot of more light out of this one than the FD 20 that is also 350 lum max. This is really a powerbomb !! Very happy with it. It runs with the 14500.

    Pound for pound, dollar for dollar. This is one of if not the best pocket flashlight on the market today. I have had many folks ask me what light I am using when we are poking around in the server rooms. Once they get their hands on it they don’t want to give it back! Light, power efficient, dependable, and bright!

    I just got this to replace my LD10 and absolutely love it. It’s small enough to be in my front pocket every day and super bright in turbo mode.

    ***** Great flashlight ! I purchased LD12 for my 13 year old daughter who was spending a lot of time in the morning at a dark bus stop. It gave her a sense of security and taught her a little bit of responsibility. she doesn’t go anywhere without it now. Not a single problem with it in a year

    I’ve had my LD12 for a while now, and I love its size and features. The fact that it uses readily available AA batteries is a plus, and it’s a perfect EDC flashlight. Well done, Fenix!

    This is my favorite flashlight I have ever owned, by a landslide. I have 2 other fenix lights, several surefires, and of course multiple other cheap LED lights. From a single AA, you can’t beat it. If I could change one thing about this light, it would be to make the tail cap button more recessed in order to do a more stable tail stand.

    Purchased to try out as an EDC light and absolutely loved it. Excellent size and form factor and tremendous battery life from a single AA. I have carried the light every day for over a year, dropped it several times and it is still going strong. After my experience with this light I ended up ordering two more as well as a few different Fenix models.

    Excellent EDC light! Small, compact and powerful, with nicely-spaced brightness levels and good run-times. All with a single AA battery!

    I have had this light for a little over a year and I love it. It is my second light from Fenix and I couldn’t give it a higher recommendation. It offers dim light when you need it or bright light if you need it. I have been carrying my LD12 everyday for about a year and it has been dropped a few times and still looks brand new. I have tested a lot of different flashlights for general every day carry / general utility light and the LD12 is currently my number one choice. Durable, dim, bright, good battery life, great light!
    Thank you for your time and good luck on your future purchase!

    A Happy Fenix Owner and Flashaholic 🙂

    Use as a carry light. The runtime is very good. The selectable power setting are very usefull. Light is well built. Surprised how bright the turbo mode is. Generally use in low setting. The small size is nice. Bought one for my son he loves it too, said he was surprise how powerful it was. Good choice for a small carry light.
