Fully press
Fully press the tactical switch to constantly turn on the light, press once again to turn off the light.

Output Selection
With the light switched on, single click the functional switch to cycle through Turbo→Eco→Low→Med→High.

With the light switched on, press and hold the functional switch for 0.5 seconds to enter strobe, click once again to return back to General mode.

Intelligent Memory Circuit
The light memorizes the last selected output excluding strobe. When turned on again the previously used output will be recalled.

Battery Replacement
Unscrew the light head to insert the battery with the anode side (+) towards the light head, then screw the light head back on.

Boot-up Battery Level Indication
Each time the light is turned on, the battery level indicator in the middle of the switch will automatically display the battery status for 3 seconds.

  • Green constant on: 85% – 100%, saturated
  • Green flashes: 50% – 85%, sufficient

  • Red flashes: 1% – 25%, critical

Note: This only works with Fenix ARB-L21-5000 21700 rechargeable Li-ion battery.

Overheat protection
The light will accumulate a lot of heat when used on Turbo or High for extended periods. When the light reaches a temperature of 50°C or above, the light will automatically step down a few lumens to reduce the temperature: the light will downshift until to 550 lumens if Turbo is being selected; the light will downshift until to 450 lumens if High is being selected.

Time-limited downshift
When the light is kept working on Turbo for over 15 minutes, the output will reduce to 900-550 lumens within 15 minutes.

Note: Tested according to laboratory cooling test conditions.

When High or Turbo is needed again, restart the light or directly cycle back if battery level allows.

Low-voltage Warning
When the voltage level drops below 3V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator blinks red to remind you to recharge or replace the battery so as not to shorten the life or damage the battery. To ensure normal use, the flashlight will work until the battery runs out or the protection circuit activates.

Note: This only works with Fenix ARB-L21-5000 21700 rechargeable Li-ion battery.


  1. When charging is needed, remove the dust cover to reveal the charging port in the light neck, and connect the light to the power source with the included USB Type-C charging cable.
  2. The indicator in the middle of the switch will be on and display red to indicate charging status, when the indicator turns green, the charging is completed. The normal charging time of the included Fenix ARB-L21-5000 rechargeable Li-ion battery is about 4 hours.
  3. Once charging is completed, be sure to remove the charging cable and push the dust cover back to protect the charging port from dust and foreign objects.
  4. Recharge a stored light every four months to maintain optimal battery performance.
  5. The light can be turned on lower outputs when it is in charging process, but the charging time will be prolonged by this act.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using a quality battery with proper built-in protections.
  • 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.
  • Lithium battery needs to be charged when it is near depletion. Please immediately charge the battery when it is depleted. It has no memory effect.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare (included) when damaged.
  • Periodic cleaning of the battery contacts improves the light’s performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons:
    A: The battery needs replacing.
    Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s specifications).
    B: The threads, PCB board contact or other contacts are dirty.
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.

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.

    I have been using Stinger lights for the past 20 or so years. I was looking for a light that ran on AA batteries specifically for use in an edc bag and I tried a Fenix light for the first time. I was instantly impressed enough to look further into the brand. My next Fenix purchase was a PD36R and WOW Love this light CRAZY bright, battery LASTS a long time, good size and simple to charge. My son just joined the AirForce – Security Forces and I bought him a PD36R with the AirForce Logo and his name on it. He LOVES it! Fenix seems to stay current with the latest “reliable” led and battery tech and as a gadget guy I REALLY APPRECIATE that.

    I bought 2 of these as gifts – one for my husband and the other for my dad. They were both very happy with the flashlights. I was very satisfied with the quality and the engraving looks great. My husband hasn’t stopped playing with his flashlight since he opened it. I would definitely recommend.

    Great light, battery charge is outstanding. My only issue is the light can be easily be turned on accidentally by sitting or placement on your person. I had the light come on and within a minute or 2, because it was on high output it actually melted the holster it comes with.

It was easy to order and I was amazed that I believe I got it within two days maybe three at the most and it was an engraved flashlight. My son picked it out so I’m sure he’s going to be happy.

    Perfect gift for my father, who absolutely loved the personalized engraving of the American Flag with his name, in honor of Veterans Day. Great size for everyday carry using the belt holster that came with this Fenix Light. Battery life is also great, easy to charge and being able to monitor the charging levels is a great feature to have, very helpful. Great product, would recommend to anyone.

    I already own the PD36R and absolutely love it. So much I bought one for my friend so he could have the same confidence in his flashlight that I do. This is the one flashlight out of the many I own that would be recommended to anyone who wants performance paired with super reliability. The battery life on this model is insane considering the power output and runtimes.

    This flashlight is now #1 in my collection. The high runtimes, easy interface, and quality features make this flashlight a no brainer purchase. At this price point you will not find a better flashlight than the Fenix PD36R. I also know the fanboys of Klarus, Nitecore, and Olight will disagree with me, but what do they really know. Remember at the end of the day they are nothing more than FANBOYS !

    It is a bit bulky to carry in a pocket, but doable. Beam is excellent. What would be a better use of all the latest tech would be to make a pen light with USB charging, 350 lumens with a 16 hour run time.

    This is a great light, powerful, slim and seems built well. I havent had it in open areas yet to really see the depth of field but it so far has performed really well. I also really like the output settings. It does get hot fast especially at max output. Overall, 5 Stars. I also bought one and engraved it for my wife who camps with her Girl Scouts and has already used it. She’s happy with hers too. Good product.

    What a neat flashlight this is. I carry it all day in my pocket during my night shift. With the cold weather approaching, this thing is a beast in the light intensity. My hands can be toasty in seconds! The features on this thing, it’s well worth the price, I wouldn’t even dare to try a different flashlight.

    I’ve had all different kinds of flashlights and some were good and some weren’t so bad but almost felt like a waste of money. This one by far… is the most impressive flashlight I have ever had. The 6 different modes are amazing because sometimes in smaller environment you need less light so you can actually see what you’re doing and don’t wanna be blinded while your looking at something small. For the outdoors you could light up a forest. It will fill an entire tree from a good distance on full power. It’s lightweight, not too big where it feels awkward in your pocket and the two way clip is awesome too. Sometimes when I need both hands to work I’ll flip my hat around forward and clip it onto the front bill of my hat. For that it’s a little heavy but you gotta work with what you have sometimes. All in all, it’s a great flashlight that I would recommend anyone who’s looking for a new daily work horse. I have a solid pen light that was very impressive to me that I used as my daily because it was so slim and worked as well as it did for its size. But since I got my new PD36R I haven’t even look at it.

    I’ve always had Surefire, but recently tried this to replace my Surefire EDCL2-t for everyday carry. I’ve only had it a couple weeks, but I love the PD36R so far and don’t see myself going back to Surefire. So far I haven’t found any downsides to this light.

    I’ve bought a few flashlights from these guys. My first one I left in a cockpit and was very bummed out but my next was even better. The hand feel and quality on these things in combination with the lumen output in such a small package makes this one of the best flashlight values on the market. I’d recommend ponying up the measly $5 extra to get it engraved. If this seems like a lot to you for a flashlight then you haven’t felt the quality difference between this and a Coast or any of the generic brands. Fenix is the real deal. Do it.

    As with all Fenix lights this one is great. I am sure it will last a long time. A few small complaints about this light include its USB-c charger which means it is one more cable on my desk, home, car, bag that I wish was ubiquitous with every other USB-micro charging cable that I own. Also I am not the biggest fan of tail-light switches but figured I would give this a try but it just sticks out too far to allow the light to stand vertically on it’s own. None of these things are a deal killer and I am sure that what I don’t like, someone else loves, but this is just my personal opinion. Overall I like it and EDC this light. My staff also appears to like it so far.

    I work in the automotive industry and we are always looking for long lasting high quality lights. This light surprised me in the amount of different lumen selections(different settings), options of engraving etc. so far after 3-4 weeks, battery life is great. tip does get hot when on the ‘turbo’ setting, but this is to be expected(so bright). And great American made company!

    This is a wonderful flashlight. It’s built extremely rugged yet the buttons are easy to access. Of the 5 intensities, 3 or 4 is all that’s normally needed. Turning it on 5 starts the branches on the tops of trees smoking. The strobe is an excellent feature.

    It’s easy and fast to charge, but no transformer is included, offered, or recommended.

    The cost for engraving is well worth it and nicely done. I’d certainly buy this flashlight again.

    As a Home Inspector it is important to be able to see deep into the attic and crawlspaces. I have been using the Fenix UC35 light daily for about a year and then bought this one. This one seems to be the same brightness but cast a beam of light just a little bit wider illuminating a better area. Very happy with this flashlight.

    Best flashlight from Fenix I have owned yet! The lowest setting is almost too bright lol. Battery life is amazing and I really like the new multipurpose clip. I like that Fenix added the new USB-C port for charging. I also like that it opens from the middle and not the back end. I was very impressed with the size as it almost the exact same size as my other flashlight with the smaller battery.

    I love this flashlight.

    My wife might tell you I have a “problem” with regards to flashlights.

    I’m always seeking out the best size vs. light output. I think I’ve finally found the perfect fit with the PD36R.

    This thing puts out so much light on its highest setting, it’s amazing!

    It’s a great form factor, and the rechargable battery (via USB C) is such a nice feature.

    If you’re hesitant on buying this one…. Just go for it. I doubt you’ll be disappointed!

    Good job fenix
