Advanced Temperature Regulation (ATR)

The flashlight is equipped with ATR technology. In Medium or High mode, the flashlight may heat up significantly. To prevent overheating and protect the internal components, the SD06 will automatically reduce its current output when the temperature reaches 55°C (131°F).

Low Voltage Warning

When the battery voltage drops below 3.0V, the SD06 will automatically switch to a lower brightness level. If the flashlight is already in Low mode, the main light will flash twice, one minute apart, to indicate that the remaining battery power is critically low. Please replace or recharge the battery promptly.

Waterproof Capability

The Sofirn SD06 boasts an IP68 waterproof rating, allowing it to be submerged up to 100 meters underwater. This makes it ideal for diving, snorkeling, and other water-based activities.
