Q: What are the key features of the Fenix HT32R?

A: The HT32R is a rechargeable hunting flashlight with up to 4000 lumens of white light (spot + flood), a 740 meter maximum beam in Spotlight mode, a 3200 lumen floodlight, and red, green, and blue light. It has a three-position toggle switch (Color light / Lockout / White light) and an electronic switch, a USB-C charging port on the neck, and comes with a Fenix ARB-L21-5500 21700 battery.

Q: What LEDs does the HT32R use?

A: A TIR multi-LED lens with 1 Luminus SFT42R LED for the central spotlight, 4 Luminus SST20F LEDs for the floodlight, and 6 Osram Ostar LEDs for the red, green, and blue light. The white light is 6500K cool white. The LEDs are not replaceable, and replacing them yourself isn't recommended, as it can affect performance or damage the light.

Q: How bright are the red, green, and blue lights?

A: Red reaches up to 400 lumens (110 m) and also has a 15 lumen Flash mode; green reaches up to 650 lumens (145 m); blue reaches up to 200 lumens (80 m). Each color also has a Low setting.

Q: How do I switch between white and color light?

A: With the light head pointing up, turn the toggle switch left to right to select Color light mode (C), Lockout, or White light mode (W). In White light mode, press and hold the electronic switch for 1.2 seconds to cycle Spot-and-floodlight, Spotlight, and Floodlight. In Color light mode, the same press cycles Red, Green, and Blue. Single click the electronic switch to change brightness.

Q: What battery does the HT32R use?

A: It comes with a Fenix ARB-L21-5500 rechargeable 21700 battery. Fenix ARB-L21-5500U, ARB-L21-5000 V2.0, ARB-L21-5000U, and ARB-L21-4000P batteries are also recommended. Do not use 18650, CR123A, or 16340 batteries.

Q: How long does it take to charge?

A: About 1.5 hours from empty to full with a 9V/3A fast-charging adapter, or about 2.5 hours with a standard 5V/3A adapter. The indicator shows red while charging and green when full. The light can be used while charging, except when a remote pressure switch is connected.

Q: Can I use a remote pressure switch with the HT32R?

A: Yes. The HT32R's tail is detachable and compatible with the Fenix AER-05 remote pressure switch. For mounting the light on a rifle barrel, it also works with the Fenix ALG-18 flashlight barrel mount. Both accessories are sold separately. Note that the flashlight can't be turned on while charging when a remote pressure switch is connected.

Q: Does the HT32R remember my last setting?

A: Yes. It remembers the last sub-mode in both White and Color light modes and the last White light output (except Turbo). Color light mode always starts in Low.

Q: How do I keep the HT32R from turning on by accident?

A: Turn the toggle switch to Lockout (the middle position). For storage or transport, you can also remove the battery.

Q: Why does the HT32R step down to a lower output after a while?

A: Two reasons. Overheat protection: at 60°C (140°F) or above, the light steps down a few lumens to cool off, then gradually returns to the set output as it cools. Low-voltage warning: when the battery runs low, the light gradually reduces brightness, and the battery indicator blinks red to remind you to recharge or replace the battery.

Q: Why does my HT32R flicker?

A: Flickering, intermittent light, or failure to turn on usually means a low battery (recharge or replace it) or dirty contacts (clean the battery and flashlight contacts with a cotton swab dipped in rubbing alcohol). If that doesn't fix it, contact Fenix Store support through live chat (the chat button on any page of fenix-store.com) or at support@fenix-store.com.

Q: What is the warranty on the HT32R?

A: Fenix provides a 15-day replacement for documented manufacturing defects, 5 years of free repair for problems from normal use (1 year for the rechargeable battery and other accessories), and a lifetime limited warranty with parts charged after 5 years. Keep your proof of purchase and contact Fenix Store support through live chat or at support@fenix-store.com. See our Warranty and Repair page (https://www.fenix-store.com/pages/warranty-info) for details.

Q: Is the HT32R waterproof?

A: Yes. It is IP68 rated and impact resistant to 1 meter. The USB-C port has a sliding cover for dust and water protection.

Battery Specifications

• Fenix ARB-L21-5000 V2.0: 21700, 3.6V — Recommended
• Fenix ARB-L21-5000U: 21700, 3.6V — Recommended

*Do not use an 18650, CR123A, or 16340 battery. 21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

Battery Replacement

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

Charging

• Slide the port cover to reveal the USB Type-C charging port, then connect the USB Type-C end of the charging cable to the flashlight.
• The indicator displays red while charging and turns green when fully charged.
• When charging fails or the battery is inserted backwards, the battery level indicator flashes red or stays off to remind you to check the battery.
• Fast charging time for the included battery is approximately 1.5 hours from depleted to fully charged with a 9V/3A charging adapter (approximately 2.5 hours without fast charging, such as with a 5V/3A adapter).

Note: the flashlight can be used while charging. Brightness may vary depending on conditions, but the number of output levels stays the same. When a remote pressure switch is connected, the flashlight cannot be activated while charging.

Battery Level Indication

With the light off, single click the electronic switch to check the battery status; the indicator lasts 3 seconds. Each time the light is turned on, the indicator also shows the current battery level for 3 seconds.

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

*Works only with a Fenix ARB-L21 21700 series battery.

Low-Voltage Warning

When the voltage drops below the preset level, the flashlight gradually reduces brightness. If the voltage is still too low, the battery level indicator blinks red to remind you to recharge or replace the battery, until the battery runs out. *Works only with a Fenix ARB-L21 21700 series battery.

Intelligent Overheat Protection

The flashlight accumulates a lot of heat when used at high output levels for extended periods. At 60°C/140°F or above, it automatically steps down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, it gradually recalls the preset output level.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the flashlight and will void the warranty.
• Fenix recommends using an excellent quality battery.
• If the flashlight will not be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage.
• Lock the flashlight or remove 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 O-ring with an approved spare.
• Periodic cleaning of the battery contacts improves performance, as dirty contacts may cause the flashlight to flicker, shine intermittently, or fail to illuminate. A. Low battery level: replace or recharge the battery. B. Dirty contacts: clean the contact points with a cotton swab soaked in rubbing alcohol. If the above methods don't work, please contact Fenix Store support through live chat (the chat button on any page of fenix-store.com) or at support@fenix-store.com.
