Headlamps, flashlights and camping lanterns: what to choose for emergencies (2026)
Which lights are worth it for a power outage or a go bag: headlamps, flashlights, camping lanterns and rechargeable emergency bulbs. Lumens, runtime, AA vs. rechargeable batteries, water resistance.
In short
- Every family member should have a headlamp: it keeps your hands free for whatever you're doing in the dark.
- For a room, an LED camping lantern lights far better than a flashlight and lasts for days.
- 100–300 lumens is enough for almost anything at home. Runtime on low matters more than maximum lumens.
- For an emergency kit, prefer models that take ordinary AA/AAA batteries or also have USB-C charging.
The first problem in an evening power cut is light. Using your phone as a flashlight drains the battery you need for communication. Candles are a common cause of fires. A few good flashlights and lanterns, kept in known places, solve the problem for days.
For the rest of your outage plan (radio, phone, power banks), see our guide to lighting and communication without power.
Which kind of light
| Type | Best for | Useful lumens | Pros | Cons |
|---|---|---|---|---|
| Headlamp | Walking, cooking, repairs, reading | 100–400 | Hands free | Only lights where you look |
| Flashlight | Searching, signaling, outdoors | 200–1,000 | Long beam, sturdy | Takes a hand |
| Camping lantern | A whole room | 200–500 | Soft light, long runtime | Bulkier |
| Rechargeable bulb | The room you’re in | 300–800 | Turns on by itself in an outage | Short runtime |
| Glow sticks | Signaling, kids | dim | No batteries, safe | Single use |
What matters more than lumens
- Runtime on low. A 400-lumen headlamp that lasts 2 hours on high is less useful than one that lasts 40 hours at 30 lumens.
- Power source. Ideally USB-C rechargeable plus the option of AA/AAA batteries.
- Red light on headlamps: preserves night vision and won’t wake others.
- Lockout mode, so it doesn’t switch on in your bag.
- Water resistance: at least IPX4.
How many you need
- A headlamp for each family member, in the go bag or by the bed
- A camping lantern for the living room and one for the bathroom or kitchen
- A flashlight by the front door and one in the car
- Spare batteries for each, ideally lithium (10–20 year shelf life)
- Glow sticks for kids: reassuring and safe
Where to keep them
- By the bed, in the nightstand drawer.
- Next to the electrical panel, so you can see what you’re doing.
- In your go bag and in the car.
- Always in the same place, so you can find them in the dark.
Maintenance
- Check them twice a year, for example when the clocks change.
- Remove alkaline batteries from lights you don’t use: they can leak and ruin the light.
- Top up rechargeable lights every 3–6 months.
For longer-term power, see the power station guide and portable solar panels.

Frequently asked questions
Regular or rechargeable batteries?
Ideally a light that takes both: a USB-C rechargeable battery that also accepts AA or AAA cells. In a long outage, when power stations and power banks run out, alkaline or lithium batteries from a drawer save the day. Lithium batteries last 10–20 years in storage and work well in the cold.
Aren't candles enough?
Candles are a common cause of house fires during power outages. If you use them, put them in stable holders away from curtains and children, and never leave them unattended. A battery LED lantern is much safer and gives better light.
What do IPX4 and IPX7 mean?
The water resistance rating. IPX4 handles splashes and rain; IPX7 can be briefly submerged. For emergencies, IPX4 is enough; for floods or long periods outdoors in rain, choose IPX7 or higher.
