• Low voltage warning: When the battery voltage is too low, the LED indicator in the side switch will start to flash rapidly. Please recharge the battery.
• Low voltage protection: The flashlight steps down automatically when the voltage is lower than 3.0V. It also turns off automatically if the voltage gets too low. Please recharge the battery.
• Advanced Temperature Regulation (ATR) technology: As the temperature rises, SP35 is programmed to automatically step down and step up the brightness. These thresholds are set at 45°C, 55°C and 65°C. The higher the temperature gets, the more the brightness will drop. Once temperature decreases, brightness will be increased again according to your selected mode.

Battery Specifications

Battery Installation

• Unscrew the tailcap to insert one 21700 battery with the anode side (+) towards the head, then screw the tailcap back on.
• Important advice: If you purchased SP35 with a battery included, please make sure to remove the insulating paper on the negative battery pole and charge the battery before first use.

Power Indicator

The LED indicator in the side switch shows the power status for 5 seconds after turning SP35 on.

• Green = remaining battery power is good.
• Red = remaining battery power is poor (less than 30%).
• Flashing Red = critical power, replace or recharge battery as soon as possible.

Recharging
SP35 offers a USB-C port for convenient recharging of its battery. Please connect it with the included USBA to USBC cable and use a USB power adapter (not included) with 5V 2A. While charging the LED power indicator flashes red. Once finished the indicator will turn green to indicate a full battery.

Operation Instructions

Group 1: Stepped mode group (default)
Stepped modes give you fixed brightness levels to choose from: Eco – Low – Medium – High, hidden Moonlight and Turbo.

• From OFF single click to turn ON. Press and hold to cycle through stepped modes (Eco – Low –Medium – High). Single click to turn OFF.
• Double click to activate Turbo mode from OFF or ON. While in Turbo mode, single click to return to the previously used mode, double click again to activate Moonlight mode.
• From OFF, hold 1 second to turn on with Moonlight mode, another hold to Eco

Group 2: Ramping group
Ramping mode gives you full flexibility to adjust brightness steplessly from Moon to Turbo level.

• From OFF single click to turn ON. Press and hold to change brightness steplessly (“ramp”). Ramping changes its direction when the button is being pressed again within 1.5 seconds. The light flashes once when it reaches the lower or upper end of the ramp. From ON single click to turn OFF again.
• Double click to activate Turbo level from OFF or ON. Another single click to return to the previously used brightness level, double click again to activate Moonlight level.
• From OFF, hold 1 second to turn on with Moonlight level.

Toggle between Group 1 and Group 2
From ON 4 fast clicks to cycle between both mode groups.

Strobe Modes
Triple click to activate Strobe mode from OFF or ON. While in Strobe mode, single click to return to the previously used standard mode, double click again to cycle through SOS – Beacon – Strobe.

Electronic Lockout
SP35 comes with a lockout function to prevent accidental activation, e.g. in one’s pocket or backpack.

From OFF 4 fast clicks to activate lockout. Another 4 fast clicks to deactive lockout again and return to the previous mode setting. When the light is locked, the main LED only blinks two times to show the status of being locked. While in lockout mode, hold the side switch to use Moonlight mode.

Safety Instructions

• SP35 is a powerful flashlight. Never point it directly at a person, animal or moving vehicles. Doing so could cause retinal damage. Please do not allow children to play with it. Strobe mode may cause seizure in persons with photosensitive epilepsy.
• Operating SP35 for a long time in high powered modes will quickly heat up the flashlight. This is normal.
• Pay close attention to the proper installation of the battery. Always check that the negative end of the battery is visible at the tube’s end before screwing the tailcap back on.
• Please unscrew the tailcap half a turn to avoid unwanted activation during transport. It also prevents the battery from draining while the flashlight is in standby.
• Avoid hitting or dropping the flashlight.

Troubleshooting and Maintenance

• Disassembling the sealed head can damage the flashlight and voids the warranty.
• Sofirn, Ltd. recommends using high-quality brand batteries. Damage by battery leakage voids the warranty.
• Remove the battery if the flashlight will not be used for an extended period of time.
• To prevent self-discharge or accidental activation during storage or transportation, unscrew the tailcap 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-rings with an approved spare.
• Troubleshooting: Clean battery contacts regularly as dirty contacts may impair the performance of the flashlight. If you experience problems (flicker, shine intermittently or failure turn on) the following root causes and solutions should be tried:
• Reason A: The battery needs a replacement (battery voltage is below 2.8V).
• Solution: Replace the battery with an approved type of a 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.
• Reason C: The flashlight will not turn on upon first use.
• Solution: Please do not forget to remove the insulation sticker from the battery on first use.
