5 Key Points for Choosing a Flashlight
① Brightness (Lumens)
The higher the lumen count, the brighter and farther the light can illuminate. Here's a guide for different uses:
| Use | Recommended Lumens | Approximate Beam Distance |
|---|---|---|
| Daily Use / Indoors | 100〜500lm | 50〜100m |
| Disaster Preparedness / Power Outage | 500〜1,000lm | 100〜200m |
| Camping / Mountain Climbing | 1,000〜3,000lm | 200〜500m |
| Night Fishing / Night Work | 3,000〜10,000lm | Over 500m |
| Military / Search & Rescue | Over 10,000lm | Over 1km |
② Waterproofing (IP Rating)
Waterproofing is crucial for outdoor and disaster preparedness uses.
| IP Rating | Waterproof Level | Suitable Use |
|---|---|---|
| IPX4 | Splash-proof | Daily use / Light outdoor activities |
| IPX5 | Jet-proof | Rainy weather / Camping |
| IPX6 | Strong jet-proof | Mountain climbing / Night fishing / Disaster preparedness |
| IPX7 | Submersible 1m, 30 min | Near water / Heavy rain |
| IPX8 | Submersible over 1m | Diving / Underwater work |
③ Charging Method
Type-C rechargeable models can be charged with the same cable as smartphones and support fast charging. Battery-operated models offer peace of mind as batteries can be replaced when they run out.
④ Lighting Modes
Multiple modes such as high brightness, medium brightness, low brightness, strobe, and SOS allow for versatile use. SOS mode is important for disaster preparedness.
⑤ Presence of COB Work Light
A COB (Chip On Board) work light illuminates a wide area from the side, similar to a lantern. It is extremely useful for inside tents, workspaces, and indoor lighting during power outages.
Recommended Choices by Use Case
🚨 Disaster Preparedness / Power Outage
Key features to prioritize: High brightness, SOS mode, long runtime, IPX6+ waterproofing, Type-C charging, COB work light
During power outages, a COB work light is invaluable for indoor illumination. A model with an SOS mode provides peace of mind for signaling. Type-C charging allows you to use the same cable as your smartphone for daily charging.
⛺ Camping / Mountain Climbing
Key features to prioritize: High brightness (1,000lm+), IPX6 waterproofing, impact resistance, lightweight, zoom function
For mountain trails and dark campsites, high brightness of 1,000lm or more is necessary. IPX6+ waterproofing for use in rain and impact-resistant design to withstand drops are crucial.
🎣 Night Fishing / Night Work
Key features to prioritize: Ultra-high brightness (3,000lm+), IPX6 waterproofing, zoomable, long-lasting battery
To illuminate distant fishing lines or dark water surfaces, ultra-high brightness of 3,000lm or more is required. A model with a zoom function that allows switching between long-distance and close-range illumination is convenient.
🏠 Daily Use / Indoors
Key features to prioritize: Compact, lightweight, USB charging, multiple modes
For daily use, a compact, easy-to-carry model with USB charging is convenient. 100-500lm provides sufficient brightness.
