  3) Instant Turbo activation rapidly responds to emergency situations.

  4) USB Type-C charging and discharging interface, supports PD3.0/PD2.0, QC3.0/QC2.0 fast-charging protocols.

  5) Battery level indication for instant checking of remaining battery level.

Q3. What kind of LED's is used in LR50R?

A: 4 Luminus SST70 cool white LED's.

Q4. Does LR50R have overheat protection?

A:Yes. It has two intelligent protection.

Time-limited downshift

With the light switched on, if Turbo is being selected for over 20 seconds, the light will downshift until to 8000 lumens within 60 seconds.

With the light switched on, if High II is being selected for over 60 seconds, the light will downshift until to 4000 lumens within 60 seconds.

Note: The abovementioned functions are specially designed for avoiding discomfort and danger caused by overheating.

Overheat Protection

The light will accumulate a lot of heat when used on High I, High II or Turbo output level 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 those modes.

Q5. What battery does the LR50R support?

A: The light includes a 3.6V/16000 mAh rechargeable LI-ion battery pack; and it is compatible with 1 to 4 21700 Li-ion battery.

Q6. What output will be activated when the light is unlocked?

A: The light will be activated on Eco.

Q7. What is the sensing distance of the Intelligent Brightness Downshifting Sensor?

A: It is approximately 85 mm. As objects of different materials and colors reflect differently to light, there will be slight deviations in the sensing distance.

Q8. What fast charging protocols does LR50R support?

A: The light and the included charging cable support PD3.0/PD2.0, QC3.0/QC2.0 fast charging protocols, the external adapter will be auto-detected if it supports the mentioned fast-charging protocols, if it does then 4.0A charging current will be selected, or 2.5A charging current will be selected.

Q9. Does LR50R have battery level indication?

A: Yes. But it only works with the included Fenix ARB-L52-16000 battery pack.
