The Fenix HT18 will be your new go-to hunting flashlight, and you can’t beat the long distance capabilities.

Battery Specifications

Type Dimensions Nominal Voltage Recommended
Rechargeable Li-ion Battery 21700 3.6V Fenix ARB-L21 Series
Rechargeable Li-ion Battery 18650 3.6V  Fenix ARB-L18 Series

Warning:

  1. The Fenix dedicated ALF-18 battery holder must be used together when using 18650 Li-ion battery.
  2. Do not use CR123A or 16340 battery. Doing so may cause damage to the flashlight or the battery being used.

*18650 /21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only using quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes.

Battery Replacement of HT18

Unscrew the tail cap and insert the battery with the anode side (+) towards the light head, then screw the tail cap back on.

Battery level indication

When the light is switched on, the battery level indicator inside the side switch will light up to display the battery status, the indicator will stay on for 3 seconds before it goes off.

  • Green light on: saturated 100% – 85%
  • Green light flashes: sufficient 85% – 50%
  • Red light on: poor 50% – 25%
  • Red light flashes: critical 25% – 1%

Note: This only works with Fenix ARB-L21 Series 21700 and Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.

Intelligent Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically step down by a few lumens to reduce temperature, until it reaches the output of 800 lumens. When the temperature has been reduced, the output will gradually return to Turbo.

Note: The above data is the test results given by Fenix through its laboratory testing. The true performance may vary according to different working environments.

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the indicator in the mid of the side switch will flash red to remind you to recharge or replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.

Note: This only works with Fenix ARB-L21 Series 21700 and Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.

Usage and Maintenance of the Fenix HT18 Long Distance Hunting 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.
  • Li-ion battery needs to be charged even if the battery is not exhausted, charge immediately when the battery is exhausted; 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.
  • Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp 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.

Warning

  1. 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.
  2. 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.

    Absolutely love this light – my new favorite! It’s incredibly small and lightweight thanks to the 21700 format and its great design and reflector. I bought this light because I wanted a light that would really throw a narrow beam a long distance, and this thing is awesome for that! It has a nice narrow, and controlled beam profile that has a super-far reach! While I don’t use it for hunting purposes, I do occasionally go exploring looking for wildlife (deer, etc) in rural areas, and regularly use it to do night-time urban exploring. Both of these lend themselves to having a very bright and very long throw without a bunch of flood / spill lighting that can attract unnecessary attention. That said, as an unexpected bonus, it does have a very dim and small bit of spill area, which also makes it surprisingly useful in smaller areas as well in its dimmer modes, such as exploring smaller rooms, areas, or in a dark car, etc. I purchased an additional USB Rechargeable battery as well, so that I always have a spare on-hand while exploring. If you are looking for super long and bright throw, small and light-weight, and great battery life – this is your light!

    I live on a farm, have numerous Fenix flashlights, and this is one of my favorites.

    I need a light with a good throw quite often and can slip this light in my jacket pocket easily. I also have the excellent TK75 2018 Edition which is incredible in its throw also (a different league really) but often it is bigger than I need when I am just working at night, or the dog wants to go out late at night and it’s he, me and a .44 Magnum.

    I do a lot of hunting and this light does not disappoint. At only $129 it’s a great deal, with excellent build quality.

    I’m a licensed Nuisance Wildlife Control Operator who does a lot of work at night. For well over the last decade I’ve tried and used many of the higher end lights out there; Surefire, Streamlight, Olight, Nitecore Thrunite, of course a number of Fenix products, and including the aspheric lens Dereelight, Wicked Lights and Elusive Wildlife Technologies stuff. The HT18 will outreach any of them in a light that can be weapon mounted. Typical Fenix quality. I’ve carried a PD35 all over the world since it came out. From the jungles of south Pacific islands to the brutal cold of northern USA; and it’s still providing yeoman’s service every day.

    Of note is the performance of the red filter. No white light with a red filter covering the lens comes close to performing as well as a red LED light; filters simply block too much light. Up until now. The HT18 is so bright that it goes toe to toe with the aspheric lens red LED’s. The red filter gives a somewhat less “red” light and therefore lights up more clearly at distance than the EWT, Dereelight or Wicked LED’s. I haven’t subjected any animals to the light yet so I can’t tell you about real world comparisons.

    Couple issues:
    #1. There’s no pressure switch available. Big drawback in a “hunting” light. Fenix must make an AER-02 V2.0 type switch to fit this light to bring the light to full potential.
    #2. The flashlight barrel is NOT one inch so 1″ gun mounts don’t fit it. It’s not 30mm either so 30mm scope mounts don’t fit. Not the worst situation on earth, a 30mm mount can be shimmed down to take the HT18 barrel.

    If you’re thinking about buying this light; you should know, it’s almost all throw. If you’re looking at using this light to do work at distances of less than 50 feet (15 meters); look elsewhere. There are way better lights for normal work at normal distances.

    HOWEVER! If you’re looking for a light that can reach out and touch some one…..this is a good choice. It’s got a tight beam with excellent throw while being relatively small for the amount of light and throw you get. I use the light at work and found a few key benefits:
    1. The barrel is about 1 inch in diameter….This means it can fit into my ASP baton holster. I think it came with a holster; but don’t feel that normal cloth/nylon holsters able to hold up to hard use day after day.
    2. Rechargeable battery via USB C means I can charge the light using my phone’s charger if I need to top off or recharge after a long session of use.
    3. Good size. It’s easy to grab and yank out of the holster based on size and not mistake it for my normal duty work light. I can draw the light without looking at it based on touch/feel.
    4. For the amount of throw; it’s “small”. It barely out performs (or matches) the LED spot light/search light mounted onto my patrol vehicle…and that light is roughly the size of a car headlight. This fits in my hand with a 3 inch cone at the end. And it’s portable.
    5. EXCELLENT reach. I can light up the far corners of a park which are over 600 feet away and clearly see what’s going on. If I respond to an apartment building; I can light up the balconies of units that are over 30 stories up and clearly see the people in them and what they are doing. At about 30 flights up; it’ll light up about 9 or so balconies within the hot spot.

    Again, this is not a good flashlight if you are only going to carry one. However, if you need light distances farther than 50 or so feet; this is a great choice at a good price point.

    Fenix has truly outdone themselves on this one. I’ve only had it for a few days but my initial impression is a solid win. The use of the 21700 battery is what really makes this a great choice for hunting since a lot of time is spent in preparation before the sun comes up and then once it goes down. Having a solid battery choice allows you to forget about the light and focus on the tasks at hand. I also have a Fenix PD36R and the battery is also a 21700 which allows you to forget about having to charge the battery often. The Fenix HT18 is almost a mini Fenix TK47UE in terms of size but don’t let the size fool you because the Fenix HT18 has almost double the candela rating! This is huge for when needing to see way out in front of yourself. The beam throw of this light, for its size, is phenomenal. If you are a hunter, police, military, or even an everyday citizen, like myself, you need this light in your kit. Get one!

    Got this for a thrower, and I wasn’t disappointed. The beam spot is very well defined and the spill is light, even, and well defined too. The tactical switch on the end of the light is nice and positive and, the mode selector is positive and sounds like the tail light cap on my TK47. I’m satisfied with the purchase. I have many lights from Fenix and they all perform well. I inspect homes, so I use my lights for hours a day. The battery life is surprisingly long, and the chargers I have perform without problem. Well done, Fenix!!
