This can stream a non-diminishing light for two hours at 60-lumen. You are not only able to use it for camping, hiking, home inspection, car maintenance, etc, thanks to its UV light mode, it is also a great tool to detect pet stains.

BRIGHTNESS ADJUSTMENT: When the flashlight is on, tap the tail switch (without a click sound) to cycle through low, medium, high modes (white light mode/ UV light mode).
TOGGLE BETWEEN WHITE LIGHT MODE AND UV LIGHT MODE: When the flashlight is on, tap (without a click sound) the tail switch twice to toggle between white light mode and UV light mode.

Safety Instructions

SF15 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.
Do not look directly at the light source or shine to eyes, may cause temporary blindness or permanent damage to the eyes.
Do not shine a UV light on your skin, may cause damage to or burn your skin.
Operating SF15 for a long time in high powered modes will quickly heat up the flashlight. This is normal.
Please unscrew the flashlight 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 tail cap 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.
Solution: Replace the 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 insulating film from the battery on first use.
