Battery Specifications 

* 16340/18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using only 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.

** The Turbo mode can not be selected and the brightness of the Strobe mode only reaches 1000 lumens when CR123A batteries are used.

Battery Replacement

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

Charging 

1. First switch off the light and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light. 
2. The indicator will display red while charging, and will turn green when fully charged. 
3. Once charging is completed, be sure to close the anti-dust cover to maintain the dustproof and waterproof ability.

Note:

1. The normal charging time of the included Fenix ARB-L18-3400 rechargeable battery is approximately 3 hours from depletion to full charging.
2. Recharge a stored light every four months to maintain optimum performance of the battery.
3. The light is unavailable while charging.
4. Charge the flashlight when it is turn on, the light will turn off immediately. After removing the charging cable, it will automatically recall the memorized lighting mode. For avoiding the risk, please turn it off before charging.

Battery Level Indication 

Each time the light is turned on, the indicator will indicate the battery level and will last 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%

Note: This only works with Fenix ARB-L18 series rechargeable battery.

Intelligent Overheat Protection            

The light will accumulate a lot of heat when used on High or Turbo modes for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user the reselection of High or Turbo modes. 

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the light blinks 3 times every 5 minutes to remind you to timely recharge or replace the battery. 

Note: This only works with Fenix ARB-L18 series rechargeable battery.

Usage and Maintenance 

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using only a high-quality protected battery. 
• If the light will not be used for an extended period, remove the battery for proper storage.
• Unscrew the tail cap 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 ring with an approved spare．
• Periodic cleaning of the battery contacts improves the light's performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: Poor battery level.
  Solution: Recharge or replace the battery.
  B: The contact or contact point of the battery or flashlight is 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.

• Do NOT shine flammable objects at close range, to avoid burning objects or causing danger due to high temperature!
• Do NOT use the light in inappropriate ways such as biting in the mouth, to avoid personal injury or life threats when the light or internal battery fails!
• This light will accumulate a lot of heat while working, resulting in a high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.
• Turn off and lock the light or remove the battery from the light to prevent accidental activation when the light is placed in a closed and flammable environment such as pockets and backpacks!
• The LED of this flashlight is not replaceable; so the whole light should be replaced when the LED reaches the end of its life.

Q1. What kind of LED is used in PD35R? Does Fenix offer to replace LED? 

A: Three Luminus SFT40 LED with a lifespan of 50,000 hours.

Fenix does not provide LED replacement services for the time being, and users are not recommended to replace the LEDs independently, which may affect product performance and cause product damage.

Q2. What is the color temperature of PD35R?

A: Around 6500K.

Q3. What is the working voltage of PD35R?

A: Voltage: 2.85 - 6V.

Q4. What is the runtime of the Turbo mode of PD35R?

A: The runtime of the Turbo mode is 2 hours and 15 minutes. The light will rapidly accumulate a lot of heat when used on 1700 lumens / Turbo mode. When the light reaches a temperature of a certain level, the light will automatically step down a few lumens to reduce the temperature. So the runtime of Turbo mode is measured in a total of runtime including output at reduced levels due to temperature or protection mechanism in the design. The stated data are from the results produced by Fenix through its laboratory testing under the temperature of 21±3°C according to the ANSI/PLATO FL1 standard. (For specific runtime performance, refer to the runtime graph in the manual)

*According to the ANSI / PLATO FL1 standard, the battery life refers to the time from 30 seconds after the flashlight switch is turned on until the light output reaches 10% of the initial value.

Q5. Is PD35R rechargeable? 

A: Yes, PD35R is rechargeable with a USB Type-C. The charging time is about 3 hours. (The indicator will display red while charging and will turn green when fully charged.)

Q6. How to prevent accidental activation of the PD35R?

A: Unscrew the light tail, or remove the battery to prevent accidental activation.

Q7. Why does the PD35R 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 light will accumulate a lot of heat when used on Turbo output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode. 

2. Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the light blinks 3 times every 5 minutes to remind you to timely recharge or replace the battery. 

Q8. Why does the PD35R happen to flicker?

A: The reasons that may cause the light to flicker, shine intermittently or even fail to illuminate:

1. Poor battery level.

Solution: Recharge or replace the battery.

2. The contact or contact point of the battery or flashlight is 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.

Q9. What kind of battery can be used in PD35R?

A: It is recommended to use 1 x Fenix ARB-L18-3400 Li-ion battery. And compatible with two CR123A batteries. The Turbo mode can not be selected and the brightness of the Strobe mode only reaches 1000 lumens when CR123A batteries are used.

Q9.  Is the PD35R internally waterproof?
