Sensor Protection Function

When the built-in optical sensor detects an obstruction ahead, the flashlight brightness will automatically decrease to prevent overheating and prolong the lifespan of the flashlight. The sensitivity of the sensor may differ due to variations in the color and material of obstructions.

• When the flashlight is in HIGH or TURBO, if the built-in optical sensor detects an obstruction ahead, the brightness will automatically decrease to 300 lumens. Once the obstruction is removed, the flashlight will return to the previous brightness level.
• When the flashlight is in STROBE Mode, if the built-in optical sensor detects an obstruction ahead, the brightness will automatically decrease to 1,200 lumens. To restore the previous brightness, simply reactivate the STROBE function.

Note:

1. This feature is only available when the flashlight is in HIGH, TURBO, and STROBE Mode.
2. It is important to keep the front lens clean to ensure that the built-in sensor functions properly to its optimal sensor performance.

ATR (Advanced Temperature Regulation)

The integrated ATR technology regulates the output of the MH12 Pro according to the working condition and ambient environment to maintain the optimal performance.

Warnings:

1. When using TURBO Mode (3,300 lumens), the head of the flashlight will generate massive amount of heat. It is not recommended for users to use TURBO Mode for an extended period to avoid burns.
2. CAUTION! Possible dangerous radiation! Don’t look into the light! May be dangerous for your eyes.
3. DO NOT cover or place objects near the head of the product to prevent accidents.
