Intelligent Over-heat Protection

The light will accumulate a lot of heat when it is working at Turbo or High output levels. When it is detected at 65℃ or above, the light will automatically and gradually lower the output to prevent overheating. The brightness will automatically return to the normal level if the light is detected below 65℃.

Battery Level Indicator

There are four LED indicator lights at the tail of the flashlight. Click the round tail switch the indicator lights will be on for three seconds. The more indicators are lit up, the more  battery power will remain. Like this, four indicators illume indicating at least 80% power remaining, one illumes indicating more than 20% remaining, and one flashes indicating 20% at most.

Over-discharge Protection

When the battery voltage is extremely low, the light will turn off automatically to protect the Li-ion battery from being damaged.

Low-voltage Downshift

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until to the lowest output to remind you to recharge the flashlight. To ensure normal use, the flashlight will not turn off automatically until Over-discharge Protection stops the battery from working.

Charging and Discharging


Plug the power adapter into an electrical outlet and confirm the LED indicator on the power adapter is solid yellow. Uncover the round charging port of the flashlight tail and connect it to the power adapter.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • 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 flashlight’s performance as dirty contacts may cause the flashlight to flicker, shine intermittently or even fail to illuminate for the following reasons:

Reason A: The battery lacks power.
Solution: Recharge the flashlight.

Reason B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please refer to the warranty policy before contacting your authorized distributor.

    love this powerhouse! this lives in our camper and when it comes out it never fails, someone asks me where did you get that!?!? up at camp we have a 2 mile stretch of logging road and its almost strait. lite this bad Larry up and you can see everything!

    uising the built in use charger to power up cellphones is also a cool feature.

    only thing i would change is just having one power button in place of the 2 buttons side by side. maybe putting the power output mode button out back near the battery indicator button, or incorporate that into the indicator button. my daughter always messes up my setting when she uses it. watching her and other people use it can be quite comical. i usually get it back on strobe mode “here shut this thing off i cant” still giving it 5 stars tho. things a beast!
