The Fenix HT18 is a powerful hunting flashlight that emits 1500 lumens of beam , with a range of almost a kilometer, battery level indicator, two switches and additional filters that change the color of the light.Solid aluminum constructionThe flashlight tube is made of A6061-T HA-III anodized aluminum , which guarantees high resistance to damage and solid construction. Thanks to the transversal crackling of the surface, the flashlight does not slip out of your hand and is easy to feel.The optical system is protected by a steel crown , which also allows the flashlight to be used for self-defence techniques. Despite the 68 mm head, the flashlight is practical and comfortable to use, with a length of 184 mm and a weight of only 250 g including the battery, which is roughly the same as a massive hunting knife.Two springs are used in the battery compartment to guarantee reliability and stability of operation, as well as resistance to recoil from hunting rifles.Impressive rangeThe light source is a new generation Cree XHP35 Hi-Led diode , which generates a maximum luminous flux of 1500 lumens for 4 hours 15 minutes (using 21700 batteries). The Emiss has a cool white colour, ideal for applications requiring maximum brightness.The human eye perceives "cold light" as stronger, making it best suited for illuminating areas and distant objects. The flashlight's capabilities are significantly enhanced by the included head-mounted colour filter.The red filter is perfect for night time activities , because unlike white light, the red stream does not blind the user, ensures a smooth adaptation of vision to seeing in the dark, makes it easier to read maps and limits our visibility.The green filter is a proven solution for hunters , because game usually does not react to green light, which makes it easier to approach and shoot accurately.The flashlight is made of anti-glare glass with high light transmission and a smooth reflector. Due to its design, the light beam is highly concentrated, resulting in an impressive 925 m range!The Fenix HT18 is a reliable searchlight that illuminates a forest wall or mountain slope very effectively and can also be used as a flashlight for hunting rifles.Simple operating modesThe user has 4 constant illumination modes : turbo, high, medium, low and 1 flash mode : flashing.The Fenix HT18 flashlight is equipped with two switches : main (rear) and side mode switch. The main button activates the momentary light and the permanent light. The steel side button is responsible for changing the brightness and activating the strobe.Thanks to the memory function, the next time the flashlight is switched on, the last light mode used is automatically selected. This feature makes the HT18 flashlight very easy and user-friendly , making it perfect for hunting, uniformed services and exploration.High capacity battery with long battery lifeThe Fenix HT18 is powered by the highest capacity ARB-L21-5000U cell , equipped with an innovative charging system via USB-C port (included).The ARB-L21-5000U is currently the highest capacity flashlight powering a torch, providing much longer operation and constant power.Thanks to advanced design and multi-level safety measures, the manufacturer guarantees up to 500 charging cycles at up to 75% capacity. This means that the cell can be charged and discharged every day within 1.5 years - clearly underlining its quality and efficiency. Due to the lack of memory effect, Fenix batteries can beThe 21700 battery is an alternative to the classic 18650 cell (not included), which can also be used thanks to the use of a polymer adapter.Battery level indicatorWhen hunting, it is worth checking the battery status, which is why the HT18 torch has a low power warning system and a simple indicator to inform the user of its status.A diode in the side switch informs you of the battery charge level for 3 seconds after the flashlight is activated.The battery charge level indicators are:steady green light: 100-85%,flashing green light: 85-50%,steady red light: 50-25%,flashing red light: 25-1%.Additional functionsThe flashlight remembers the last brightness level used. When you switch it on again, the flashlight is automatically activated in this mode (memory function). The flashlight has a high IP68 protection class, making it resistant to dust, full immersion in water up to 2 m and drops from a height of 1 m. The manufacturer has not forgotten to include protection against overheating and reverse polarity, as well as a controller with digital current regulation.The light parameters have been tested with ARB-L21-5000 and ARB-L18-3500 batteries.DiodeModeLuminous flux [lm]Working time 21700 [h min]Working time 18650 [h min]Range [m]Luminous intensity [cd]white turbo15001 h 40 min1 h 40 min925/805214187/162682high5004 h 15 min2 h 50 min57080877medium15020 h 15 min14 h 10 min30021567short thirty 61 h 53 h 1606379stroboscope1500----SPECIFICATIONSPage informationNumber of operating modes 5 Working time [h min] 53 Luminous flux [lm] 1500 Range [m] 925Technologies used Diode type white: Cree XP-L HIA diode lifetime up to 50 000 hoursSafetyIP sealing class IP68 PowerCell type acceptable reusable battery (secondary)Power21700 × 1,18650 × 1 Power source cellsFurther detailsColour blackLuminosity [cd] 214187Housing material according to anodized duralumin MIL-SPECCover material made of / made of nylonDrop resistance [m] 1DimensionsOverall length [mm] 184Weight without batteries [g] 220Base diameter [mm] 68Body diameter [mm] 26IncludedBatteries of the flashlight kitFenix ARB-L21-5000 21700 5000 mAh battery,green filter,red filter,manufacturer's manual,short armband (bow) (neck strap),spare rubber switch,spare O-ring × 1 (spare gasket)
