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.

Note: This only works with Fenix ARB-L21 Series 21700 rechargeable Li-ion battery.

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.

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.

    Solid built. Not a fan of the buttons and how you interact with them to turn on/off and mode swap.

    It is a durably made flashlight and the Turbo mode is extremely bright. In my opinion it’s a bit bulky for EDC unless you have a belt pouch for it. The control switch works well but I have a hard time finding it with a fingertip when it’s truly dark outside. The rechargeable battery is powerful and long lasting, but you must remove it from the flashlight to charge it; there’s no port on the side of the light. So I’m giving it four stars out of five; it’s pretty good, but there is definitely some room for improvement. For the price, it is worth having. It is not the last high performance flashlight I’ll ever buy, though.

      Hi Geoffrey – we do find that for the side switch lights, lining up the pocket clip with the switch is helpful if you struggle to find the button. Also, if you are looking for a light with the port on the light itself, I would recommend you look for one of the lights with an “R” in the name (i.e., PD36R, E28R, TK26R etc) as the R denotes that the light itself is rechargeable.

    I am a bit of a flashlight nut so when i am impressed by a light, it must really be good. This is a great little unit, witht he rechargeable battery and totally sealed case, it is easy to operate and very flexible. It has a super bright mode that is unreal – you can not use it on that setting for too long because the case is small the heat generated is tremendous, but for a few minutes at a time, it is spectacular. I set it to the mid setting which gives lots of light, no heat and long runtimes and the firmware remembers the last mode used and returns to it when you switch it back on again. This is a great light and would be a great gift for anyone who needs a good compact light that can really shine when needed. Very impressed by this unit!

    I gave this one to a close friend and he loves it. This friend demoed his to an acquaintance who recently ordered two for himself. This is a great light with unbelievable power in a compact case.

    So far so good, I’m rough on flashlights as I use them at work mainly so they get bumped around, dropped and rough handled on a daily basis. So far this one has held up just fine. Time will tell however. I usually break them before 6 months is up.
