The HT18 is a long range torch and the first torch in the HT series, with a Fenix 21700 500 mAh USB rechargeable battery (ARB-L21-5000U) that is included as standard.
Utilising a Luminus SFT40 LED combined with a large metal glossy reflector, it offers a maximum output of 1500 lumens on turbo and throws the beam up to 925 metres range distance, providing an excellent combination of output and distance.
Designed with hunting in mind, it comes supplied with two filters in red and green to help preserve natural night vision and to avoid spooking game, however the outputs and beam range will be reduced when using the filters. The filters feature a lanyard hole so that it can be attached to the torch via the included lanyard and if they need to be removed quickly when in use, simply pop the filter off the end of the torch and it will hang from the tail. The battery compartment is also designed with a spring at the positive and negative terminal to keep the battery in place and resist external impact such as recoil.
The HT18 is powered using the included Fenix 21700 5000 mAh USB rechargeable lithium-ion battery for best run-times due to the larger capacity, and is charged outside of the torch via the Type C charging port on the battery itself using the included Type C charging cable for fast charging. Alternatively you can use an 18650 lithium-ion battery (not included), however the 18650 battery must be inserted in the included ALF-18 battery holder before inserting it into the torch and would require a separate battery charger to be recharged.
Four brightness levels, plus strobe mode are available and operated with the tactical tail switch and side functional switch. The HT18 is turned on and off with the tactical tail switch by fully pressing it down, and it also offers a momentary function by half pressing the button (the light will turn off when the button is released). Once the torch is on, the side switch will cycle through low, mid, high and turbo with each press.
Strobe is activated by holding the side switch for 0.8 seconds when the torch is turned on and a single press will return the torch to the previous brightness setting. The last used brightness setting (excluding strobe) will be remembered next time the light is turned on.
When the torch is turned on a battery level indicator built into the switch will light up for 3 seconds with either a green, green flashing, red or red flashing light to show the battery power remaining and notify you when the battery needs charging.
When used in turbo the overheat protection will automatically reduce the output to 800 lumens when the internal temperature exceeds 65° in order to protect the LED from overheating. Once the torch has cooled the lumen output will gradually increase again. The torch can withstand operation in extreme temperatures between -35° to 45°, though a cold weather battery is recommended in cold situations.
