Intelligent Overheat Protection
The light will accumulate a lot of heat when used on Turbo and High output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode.

Usage and Maintenance of the E35 V3.0 3000 Lumen Flashlight

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality 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.

  1. Frank

    I agree with everyone here it is a very bright and super compact for size and weight and power.
    Also agree that it should have a tail switch and a reversible clip and better cooling. Great expensive hand warmer.
    Version 4.0. Give people a choice.
    I am done with cheap eBay and Amazon lights. Have a drawer full. This is the best light period.

    • Dianne

      Hi Frank – just a note that we do have many lights using a tail switch, so the E35 V3.0 was created for those customers that prefer side switch and tail stand.

  2. Dustin (verified owner)

    In spite of the lockout function having been used, the light turned on in my pocket and I noticed the smell of smoldering fabric at the same I felt my leg getting warm. Thankfully, I was able to get to the light before any real damage was done.
    Aside from this issue, I find the flat smooth profile of the button difficult to locate in the dark, particularly with a cold or gloves hand.

    • Dianne

      Sorry to hear that the lock function got unlocked. One way to be extra cautious with it is to give the head a slight turn so that the battery is disengaged, which will keep it from turning on accidentally too. Quick turn to tighten and the light is good to go. We have several people who have found that lining up the pocket clip with the button helps locate it easier when wearing gloves.

  3. John J. (verified owner)

    It’s very good, gets hot when on highest beam, I like the battery charge indicator,prefer the off/on to be on the end.

  4. Rey M. (verified owner)

    Very good quality flashlight. So proud I finally owned one.

  5. Richard L. (verified owner)

    Super bright! Lights up the woods & fields behind my house when I need to chase the coyotes away.

  6. shane H. (verified owner)

    Super bright, nice compact size, just wish batteries weren’t close to 1/2 cost of the light

  7. Nick (verified owner)

    I bought this for my wife. (I own the PD36R – best flash light ever made). She did not want the rear button and has a smaller grip. Overall very good, still looking for the 1400 Lumens over the PD36R, we don’t see that much a difference. Regardless Turbo is still very bright. Only issue, the entire light gets very HOT on turbo and to a lesser extent on High mode. Good quality and operation, just don’t keep on Turbo for too long. We’ll keep it, but we are not as thrilled as we are with the PD36R

    • Dianne

      Due to the different beam patterns the brightness will appear different.

  8. MIGUEL (verified owner)

    I love this light, I wanted to be able to walk at night and this is perfect. Super bright!

  9. Michael Wilson (verified owner)

    A tailswitch would be nice. Otherwise I am pleased with its performance

    • Dianne

      Hi Michael – we do note on the page that this light does NOT have a tailswitch.

    Love this flashlight – already have one but putting this one in another room

  11. Terry Davis (verified owner)

    I love the light.I would like a single button that goes right to high beam.I would not change anything else.

  12. Darrin Padilla (verified owner)

    Great flashlight. I’m a big fan of Fenix. The only downside is it didn’t come with a holster. I think all flashlights should come with the appropriate size holster.

  13. Gerald (verified owner)

    Absolutely enjoy this flash light. Very bright. The only thing I would like is a tail cap button. Fenix needs to add it as an accessory.

    Worth every penny. I do wish the battery lasted longer on high though.

    Just when I think I’m on the highest output level, it has one more level up.

    I was looking for a high output compact light for dog walking. Safety first. The quick push for strobe is perfect to remind cars to slow down

  22. Ralph Kitchens (verified owner)

    Great product. Amazing brightness in such a compact light.

  23. Joe A. (verified owner)

    This is a very well made flashlight, I own other well known brand name flashlights, but I always carry my Fenix with me. Don’t hesitate to purchase this one, you will not be disappointed.

  24. Robert Finklea (verified owner)

    Works as advertised. There was a manufacturing issue that delayed shipment but Fenix called me and was more than willing to offer me an upgrade or faster shipping in compensation. Easy to use, clear instructions and seems well made.

  25. John Villalovos (verified owner)

    The light works great as far as lighting things up and performing it’s operations is concerned. However, the Lock-Out function failed in my situation. I Locked out the light with two quick button pushes and saw the confirming two quick flashes of light. Then the light was off and I pushed the button once, a few times, to try to turn it on and it would not turn on, just as intended. I then carefully put the light into my PD35 Tac holster and threaded my belt through the belt loop for waist belt carry. I then drove in my car for about a 45 minute trip. Somehow, the light still turned on during my drive and it melted and burned a hole through the bottom of my holster! It’s now evident to me that your programming of two quick button pushes are insufficient to maximize the odds of keeping the light locked out. Somehow, my movements in the car, still enabled the light to turn on and get out of the lock-out mode. I suggest you re-program these lights to require 4 or 5 quick button pushes to keep them locked out, when the power button may rub against holsters or carry bags due to typical movements.

    • Dianne

      Hi John, since the E35 V3.0 is side switch only, unfortunately I can see that the button might get pressed when it’s in a holster. Another way to “lock” it out for a holster is a slight turn on the head – enough to disengage the battery connection.

  26. PAUL (verified owner)

    The brightness of the light is awesome. However, why would the on/off switch move to the same as the brightness selector. HUGE MISTAKE. Many of times the light will turn on bc of the power button on the side. Either in my pocket or work bag. Extremely bad design. Should have kept the power button on the bottom.

    • Dianne

      We do make sure to note on the page that this does not have a tail switch and the side switch is used for everything. You may want to use the lock out mode if it’s turning on in your pocket or bag. Or, a slight twist of the head is enough to disengage the battery so that it won’t turn on.

      Lock: with the light switched off, double click the switch within 0.5 seconds to lock the light, the light will blink twice on Eco to indicate locked status.

      Unlock: with the light locked, double click the switch within 0.5 seconds, the light will be unlocked and activated on Eco.

      *In locked status, clicking or pressing the switch will activate 2 one-second blinks on Eco to indicate locked status.

    I bought this just cause of the one start review. Good Stuff. Lol

  28. Sidney P. (verified owner)

    Good light with plenty of power and good options for light levels. The power button could use a protector though to prevent unintended activation. The battery status indicator in the power button is very handy! Overall, a great purchase.

    • Dianne

      Hi Sidney – please note the light does have a lock out option:

      Lock: with the light switched off, double click the switch within 0.5 seconds to lock the light, the light will blink twice on Eco to indicate locked status.

      Unlock: with the light locked, double click the switch within 0.5 seconds, the light will be unlocked and activated on Eco.

      *In locked status, clicking or pressing the switch will activate 2 one-second blinks on Eco to indicate locked status.

    Rock solid and reliable. Tired of cheap amazon flashlights that last 3-6 months or knock offs

  30. John D. (verified owner)

    Very compact very bright and if I was to change one thing I would add a tail switch

  31. Paul (verified owner)

    Love the 3000 lumens.

  32. Robert W. (verified owner)

    Everyone I spoke to is so incredibly nice and helpful. Also the flashlight is amazing


    I don’t own this flashlight but from reading the review from the person that gave it one star I’ll be buying it directly.


    Forgive me but some people shouldn’t be in here buying high out put flashlights if they plan on holding them against they’re pants. I will be getting this light when they’re available. I currently have the PD36 and it’s the best light I own. But I agree with another reviewer that this light should come with a reversable pocket clip, which begs the question; will the pocket clip from the PD36 fit on the E35V3?

    • Dianne

      The PD36R clip is a liiiiitttle bit wider. But it will work.

  35. (verified owner)

    Love the light. I wish it had an external charge connection in lieu of removing battery.
    Great light overall

    Good price and light for the price but not for a road officer

  43. Branden B. (verified owner)

    Excellent flashlight! It’s the first flashlight I’ve paid more than ten dollars for and it really shows. Extremely bright and compact. Good battery life, charges with the same charger as my phone (USBC). It sure does get hot at the High and Turbo settings, but as I’m in a northern state, it also makes for an excellent hand warmer! It can tail stand which I really like. I’ve been able to wash it as its waterproof. It seems to be very durable. I’ve dropped several times without any damage. As a future Aviation Mechanic, I have a feeling that this flashlight will last me for a long time. The locking feature allows me to carry without worrying that it will be accidentally turned on when carried in my pocket.

    Pro: 3,000 Lumen Max, Compact, Rechargeable 5,000 mAh battery, Gets hot, Nice battery life indicator, nice feel in hand, Good locking feature. Strobe can be activated from off, Clip feels sturdy and tight.

    Con: Need to remove head to charge it, non-reversible clip, gets very hot quickly (won’t be very nice when summer comes around).

    What I’d like to see in the future: A more aggressive cooling design, an aftermarket double-sided clip that I could purchase separately, maybe a version of the same flashlight with a tail switch. Alas, I’m very pleased with this purchase for the price I paid. Thanks Fenix!

  44. Dan Wolff (verified owner)

    Was hoping to use the highest setting for long periods of time. I had the light on Turbo for no more than 1 minute and was holding it on top of my hunting pants. The light proceeded to burn a hole in them. This light is dangerous and could start a fire or burn the user easily. Had I know this I never would have purchased it. Very disappointed and shocked.

    • Dianne

      We do not recommend shining any light on Turbo at something flammable very close up, or on the surface of anything flammable. The following information is posted under the operating instructions on the product page and is also included with the light:


      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.

      This flashlight will accumulate a lot of heat when used for extended periods, resulting in high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.

    I saw this light shortly after it was released, and couldn’t wait to get my hands on it! It has now become my most-used flashlight due to the great combination of it’s size, high-lumen output, wide-beam, and great runtime. I find myself using it a number of times per day (to let the dog out, look for things in the garage and basement, take out the trash, see what’s happening in my wooded back yard, etc), and am always surprised to find the very convenient battery indicator still solid green! The 3k Lumen Turbo is great for completely blasting and lighting up the world in front of you. The ads media designed for this light tout it having a wide-angle beam, and the beam profile width is definitely noticeable compared to other EDC-style lights. Again, this makes is a fantastic go-to light for general use. Also, a little helpful tip for using this light: It does have mode memory, meaning that when you turn it on, it will conveniently power up to the last-used brightness level. That said, if you want to start this light in it’s lowest (ECO) mode, this can be accomplished even if the last-used mode was high, turbo, etc. When this light is taken OUT of lock out mode (via a double-press from off), it will power on to it’s lowest ECO mode. So…if the light is off and you want to insure the first power on isn’t blinding, simply double-click to lock it out (it will flash twice at low / ECO brightness), and then double-click it again to unlock it. You will then be in low/ECO mode automatically 😀 This light feels solid and well-built with the quality that we’ve come to expect, recognize, and appreciate from Fenix.

  52. Michael Bonin (verified owner)

    This is a very bright light, especially considering it’s size. It would most definitely take the top spot for my EDC light IF they would have kept the tail activation for momentary on. I plan to carry it as a back up, but my Fenix LD30 will remain my primary. Yes I recommend this new upgrade due to its insane brightness, but if you are like and use that momentary on tail button, I would recommend the LD30. It offers 1600 lumens which is still great, but needless to say this newer model will have a further throw.

  53. marcin.gaio (verified owner)

    WOW, very impressed with this light. For the size it is by far the best flashlight I have ever owned. You can see and feel the quality that goes into the product!

  54. Terry

    This is an extremely bright flashlight, made very well and it looks great. It is very easy to operate with just one side switch to click on to obtain all the different settings. The eco setting has an extremely long run time and is perfect for use when brightness is not needed or wanted, great for finding objects and for reading. This is my first Fenix flashlight and it will not be my last. I am very pleased with this flashlight, it’s performance and with the obvious construction quality. 5 stars.
