ANSI NEMA FL1 Chart

• Notice: The above-mentioned parameters are based on tests according to international flashlight testing standards (ANSI/NEMA FL1) using one 4000mAh 21700 Li-ion battery in our laboratory. Results may vary with different batteries or under different environmental conditions.

Specification

• CREE XHP50.2 LED with a lifespan of 50,000 hours
• Working Voltage: 3V-4.5V
• Battery Options: One 21700 or 18650 Li-ion battery
• Dimension: 119mm (length)× 37.5mm (head diameter)
• Weight: 120 grams (without batteries)
• Premium type Ⅲ hard-anodized anti-abrasive finish
• Magnetic rotating ring for one-handed operation
• Reverse polarity protection from improper battery installation
• Low battery warning: The flashlight is rapidly flashing every minute to indicate low battery. If the voltage is lower than 3 volts, please insert a new battery.
• Automatic Stepdown: The flashlight will slowly step down to lower mode after 3minutes of operation in the high mode to prevent overheating.
• Low voltage protection: The flashlight turns off automatically if the voltageis lower than 2.6 volts. Please recharge the battery

Caution:

• Do not mix used and new batteries.
• Operating for a long time in “High Powered” mode will warm up. This is normal.
• Do not stare directly into the beam or point it directly into anyone’s face

Battery Specifications:

Operation Instruction

• Rotate the magnetic ring to turn on/off the light to select the desired output level. From left to right: off, Low, Medium, High

Safe Diving Illumination Design

• If the detected voltage is too low for the High Mode, the output will automatically step down to prolong the runtime. Advanced Temperature Regulation (ATR) technology
• The light will accumulate a lot of heat when used at High Mode for extended periods.
• If the light reaches a temperature of 55℃(131 °F) or above, it will automatically step down by a few lumens until it doesn’t get hotter. Meanwhile, after being used at High Mode for 3 minutes, the light steps down slowly until Medium Mode is reached.

Troubleshooting and Maintenance

• Disassembling the sealed head can damage the flashlight and void the warranty.
• Sofirn, Ltd. recommends using high-quality brand batteries. Damage caused by battery leakage voids the warranty.
• Remove the battery if the flashlight will not be used for an extended period of time.
• To prevent accidental activation during storage or transportation, unscrew the head by half a turn or remove the battery.
• Every 6 months, threads should be wiped with a clean cloth followed by a thin layer of silicone grease.
• To maintain a proper level of waterproofness, replace worn-out O-ring with an approved spare (2 pieces are shipped with the initial order). Troubleshooting: Cleaning battery contacts regularly, as dirty contacts may impair theperformance of the flashlight. If you experience problems (flicker, shine intermittently, or failure to turn on), the following root causes and solutions should be tried:
• Reason A: The battery needs replacement (Battery voltage is below 2.8V). Solution: Replace the battery with an approved type of fully charged battery. Reason B: Threads, PCB board contact, or other contacts are dirty. Solutions:
• Please clean the contact points with a cotton swab soaked in rubbing alcohol.
• If the above methods do not work, please refer to the warranty policy before contacting your authorized distributor. Solutions: Please clean the contact points with a cotton swab soaked in rubbing alcohol.
