$168.00 $129.95

The Fenix HT18 hunting flashlight is a hand-held long-distance flashlight that can throw a maximum 1500 lumens 3,035ft (925m)—that’s over half of a mile! Extremely small, this flashlight is only 7.2” long and weighs only 7.8 oz (excluding battery), nearly half the size of other flashlights that deliver that type of power. Hunters will appreciate the included red or green filters allowing you to filter the light, preserving your night vision and reducing the chance of spooking prey. The Fenix HT18 will be your new go-to hunting flashlight, and you can’t beat the long distance capabilities. Extend runtimes when using the included 21700 li-ion battery and know its status with the battery level indicator. IP68 rated waterproof and dustproof rounds out the features of this spotlight built for those needing a small, tough flashlight with an incredibly far beam distance.

  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.



  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.

Sweet Light

I own this fantastic light and am really digging it! Only thing that is missing is a 3-5 lumen eco mode which would have made it damn near perfect and would have made run time that much better! Not sure why Fenix refuses to use moon mode or low eco mode in their newer lights.....

Daniel Matlock
Great light

I was so impressed with the first one I bought a second

Long distance with two useful filters

The HT18 shines a focused warm spot a long distance. Most of my flashlights light the path ahead but the HT 18 reveals the distant darkness. The useful red and green filters provide beams of light that I have never seen before. I highly recommend the Fenix HT18.

Fenix ht18

Super bright long throw flashlight with an awesome run time. Very high quality and I was super impressed with the light!

HT 18

Excellent flashlight. I have purchased cheaper lights in the past. They normally stop working within a year. I decided to purchase a higher quality flashlight and after reading reviews I purchased the HT 18. It is a great flashlight with a very long reaching beam of light. I live on a small lake and use it almost nightly. I have had the light for a couple of years now and the rechargeable battery is starting to show signs of holding a charge less. I can't complain. Great Product!!!
