|---|---|---|
| ① Large capacity battery | Can continue to be used even if power outages are prolonged | 3,000mAh or more, USB charging compatible |
| ② Waterproof performance | Usable during typhoons, heavy rains, and flooding | IPX5 or higher |
| ③ Multiple lighting modes | Allows for adaptable use depending on the situation | High, medium, and low brightness, SOS |
| ④ SOS flash function | Essential for requesting rescue and indicating location | SOS mode equipped |
| ⑤ Impact resistance | Withstands drops and impacts during evacuation | Drop resistance of 1m or more |
5 Ways to Utilize Your Flashlight During a Power Outage
① How to Make an Instant Lantern
By standing your flashlight upright and placing a white, translucent plastic bottle (filled with water) over it, the light will diffuse, turning it into a lantern that illuminates the entire room. The water diffuses the light, allowing one flashlight to illuminate a wide area.
If you have a model with a zoom function, setting it to wide-angle mode will further enhance the diffusion effect.
② Conserving Battery Power with Low Power Mode
If a power outage is prolonged, utilize low brightness mode (10-50lm). This extends the lighting time by 3-5 times compared to high brightness mode. The basic principle is to use high brightness for movement and low brightness when stationary.
| Brightness Mode | Purpose | Approximate Lighting Time |
|---|---|---|
| High brightness (1,000lm or more) | Outdoor movement, wide-area illumination | 2-4 hours |
| Medium brightness (200-500lm) | Indoor movement, work | 6-10 hours |
| Low brightness (10-50lm) | Sleeping, stationary lighting | 20-50+ hours |
| SOS flash | Rescue request, emergency signal | Long-duration support |
③ Using SOS Mode to Request Rescue
SOS mode automatically flashes the international distress signal (・・・－－－・・・). Use it when trapped in a building or when you need to indicate your location in the dark. Flashing it towards a window makes it easier for rescue teams to spot you.
④ Linking with a Mobile Battery
USB-chargeable flashlights can be charged from a mobile battery. Even during a power outage, a mobile battery with 10,000mAh or more can fully charge your flashlight multiple times. Conversely, some flashlights with large capacity batteries (with mobile battery function) can charge your smartphone.
⑤ Ensuring Safety During Evacuation
During nighttime evacuations, move while illuminating your feet with wide-angle light. Checking for dangers like steps, puddles, and broken glass in advance can prevent falls and injuries. If moving with family, it's safest for the person at the front and the person at the back to each carry a flashlight.

Storage and Maintenance of Disaster Preparedness Flashlights
- Every 3 months: Check charge level and recharge
- Every 6 months: Test all lighting modes
- Annually: Clean lens and body
- Storage locations: Distribute in 3 places: entrance, bedroom, car
- Confirm that all family members know the storage locations
- Check and practice if children can operate it
Recommended Storage Locations
Ideally, flashlights should be stored in three locations: the entrance, bedroom, and car. This mitigates the risk of being unable to retrieve them if furniture topples during an earthquake. It is also crucial to keep them in places accessible in the dark (e.g., bedside table, entrance shelf).
