Q2. What kind of LEDs are used in HM62-T? 

A: One Luminus SST40 white light LED and two 2835 red light LEDs; with a lifespan of 50,000 hours each.

Q3. What is the color temperature of HM62-T?

A: The color temperature is 4500-5000K.

Q4. What is the operating voltage of HM62-T?

A: The operating voltage is 2.85V-7.4V.

Q5. Is HM62-T rechargeable? How long is the charging time?

A: The included 3400mAh is rechargeable. Charge the battery by inserting the USB Type-C end of the charging cable into the battery’s charging port. Charging the Fenix ARB-L18-3400U V2.0 using a 5V/2A charging adapter (not included) takes approximately 3 hours from drained to full.

Q6. How do I prevent accidentally activating the HM62-T?

A. Lock out the switch: with the lamp switched off, press and hold the switch for 3 seconds, the lamp will blink 4 times on the Low output of white light mode to indicate locked status. To unlock with the lamp locked, press and hold the switch for 3 seconds, the lamp will be activated on the Low output of white light mode. In locked status, clicking or pressing the switches will activate 4 blinks on the Low output of white light mode to indicate locked status.

Q7. Why does the HM62-T downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: There are two reasons:

1. Intelligent Overheat Protection. The lamp will accumulate a lot of heat when used at relatively high output levels for extended periods. When the lamp reaches a temperature of 50°C or above, the lamp will automatically step down a few lumens to reduce the temperature.

2. Low-voltage Warning. When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Eco output is reached.

Q8. Why does the HM62-T happen to flicker?

A: There are a couple of reasons that may cause the lamp to flicker, shine intermittently, or even fail to illuminate:

1: Poor battery level. Solution: Charging the battery or replace the battery (Ensure battery is inserted according to the manufacturer’s specifications).

2: The contact point or contact of the battery or headlamp is dirty. Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol. 

If the above methods don’t work, please contact the distributor.

Q9. What kind of battery can be used in HM62-T?

A: Fenix ARB-L18-3400U V2.0 battery is recommended but it is also compatible with 2 x CR123A batteries. Other Li-ion batteries are not recommended because the current and voltage output of other batteries may cause the headlamp to fail or not work properly.

Only quality batteries with circuit protection will reduce the potential for combustion or explosion; cell damage or short circuiting are potential risks the user assumes.

Battery Replacement

Unscrew the battery cover counterclockwise to insert the battery in accordance with the polarity marks, then screw the battery cover back on.

Charging

• Turn off the light and unscrew the battery cover counterclockwise to take out the battery, then connect the USB Type-C end of the charging cable to the battery.
• The indicator on the battery will display red while charging, and will turn blue when fully charged.
• Once charging is completed, be sure to unplug the charging cable and insert the battery in accordance with the polarity marks, then screw the battery cover back on.

Battery Level Indication

With the light switched off, single click the side switch to check the battery status; the indicator in the switch will last for 3 seconds. Each time the light is turned on, the indicator will show the current battery level for 3 seconds.

• Green light on: 100% - 80%
• Green light flashes: 80% - 50%
• Red light on: 50% - 20%
• Red light flashes: 20% - 1%

Note: this only works with a Fenix ARB-L18 Series battery.

Intelligent Overheat Protection

The lamp will accumulate a lot of heat when used at high output levels for extended periods. When the lamp reaches a temperature of 50°C/122°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 50°C/122°F, the lamp will gradually recall the preset output level.

Low-Voltage Warning

When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Low output is reached. When this happens at Low output, the lamp blinks 3 times every 5 minutes on the Low output of White light mode to remind users to recharge or replace the battery. Note: this only works with a Fenix ARB-L18 Series battery.

Headband Assembly

The headband is factory assembled by default. Rotate the dial clockwise to tighten the headband, and rotate the dial counterclockwise to loosen it. When the headband hits its maximum length, keep rotating the dial and the operation direction will reverse.

Usage and Maintenance

• Disassembling the sealed body can cause damage to the lamp and will void the warranty.
• Fenix recommends using an excellent quality Fenix battery.
• If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
• Lock the lamp or take out the battery to prevent accidental activation during storage or transportation.
• Periodic cleaning of the battery contacts improves the lamp's performance: A) The lamp is locked — press and hold the switch for 3 seconds to unlock. B) Poor battery level — recharge or replace. C) Dirty contacts — clean with a cotton swab soaked in rubbing alcohol. If the above methods don't work, contact the distributor.
