Lumens, runtime, batteries, red mode and water resistance explained, so you buy the right light for each room.
Key takeaways
- Skip candles. Use LED headlamps and lanterns.
- Check runtime at low and medium brightness, not just maximum lumens.
- Keep one headlamp per person and spare batteries.
Skip candles. They are a fire risk and add carbon monoxide risk in small closed rooms. Use LED headlamps and lanterns instead.
Headlamp or lantern?
| Light | Best for |
|---|---|
| Headlamp | Hands-free tasks: cooking, repairs, reading in bed, walking outside |
| Lantern | Lighting a room for a family |
| Small flashlight | Quick checks. Keep one per bedside |
Specs that matter
- Lumens: brightness. 100 to 300 is plenty indoors. More brightness shortens runtime.
- Runtime at a stated brightness: look for the figure on low and medium settings, not only the maximum.
- Power: rechargeable (USB) is convenient, and AA or AAA batteries are easy to swap in a crisis. A mix is sensible.
- Red or low modes: preserve night vision and battery.
- Water resistance: an IPX rating shows resistance to water.
A simple plan
- One headlamp per person, stored in a known place.
- One lantern for the main room.
- One flashlight at each bedside.
- Spare batteries in the right sizes, checked each autumn.
A power station can also run LED lights for many hours, but dedicated lights are cheaper and more reliable.
