Candles vs Flashlights in a Power Outage: Safer Lighting
This post contains affiliate links. I earn a small commission if you buy through my links, at no extra cost to you. I only recommend gear I have researched in depth: manufacturer specifications, published teardowns, and aggregated owner reports.
Use flashlights or battery-powered lights, not candles. Fire safety agencies, including the CPSC and the US Fire Administration, advise battery-powered lighting during an outage because an open flame in a dark, stressful house is a fire risk.
How the numbers work: wattages are typical ranges from manufacturer spec sheets and efficiency labels, so check the label on your own appliance. Runtimes are calculated, not lab-tested: usable energy = rated Wh × 0.85, divided by average watts.
⚡ Quick Answer
- First choice: flashlights, headlamps and battery or rechargeable LED lanterns.
- If you must use candles: never leave them unattended, keep them away from anything that burns, and use sturdy holders on a stable surface.
- Keep kids and pets away from any flame.
- Blow them out before sleeping or leaving a room.
- Store spare batteries and recharge lights when power is on.
💡 Why Flashlights Win
A candle can be knocked over in the dark, ignited by drafts blowing curtains or paper, or left burning when you fall asleep. A flashlight has none of those risks, and modern LED lights are bright and run for many hours per charge.
🔋 How Long a Power Station Runs LED Lights
LED lanterns draw only a few watts. Assuming about 5 W each (check your own label), here are estimates at 85% usable capacity:
| Lighting load | EcoFlow DELTA 3 Plus | Jackery Explorer 1000 V2 | Bluetti Elite 200 V2 | EcoFlow DELTA Pro | Bluetti EB3A |
|---|---|---|---|---|---|
| 5 LED lanterns/lights (about 5 W each, 25 W total) | 34.8 h | 36.4 h | 2.9 days | 5.1 days | 9.1 h |
| 10 LED lights (about 50 W total) | 17.4 h | 18.2 h | 35.3 h | 2.6 days | 4.6 h |
Those are calculated estimates, not manufacturer ratings. Lights are among the cheapest loads you can run, which is why a power station can light a home for days. See the router, TV and phones guide and the appliance wattage guide.
Quick picks
EcoFlow DELTA 3 Plus (1,024Wh, 1,800W): runs lights, phones and a router together for many hours. Check the current listing on EcoFlow's site.
Bluetti Elite 200 V2 (2,073.6Wh, 2,600W): longest runtime of the three in this guide. Check Bluetti Elite 200 V2 Price
Jackery Explorer 1000 V2 (1,070Wh, 1,500W, 3,000W surge): lighter and cheaper. Check Jackery Explorer 1000 V2 Price
🧰 Basic Outage Lighting Kit
- One flashlight or headlamp per person.
- Two or three LED lanterns for shared rooms.
- Spare batteries, or a power bank to recharge USB lights.
- A battery or hand-crank radio for alerts.

❓ Frequently Asked Questions
Are candles safe during a power outage?
Fire safety agencies recommend flashlights and battery-powered lights instead. If you use candles, never leave them unattended, keep them away from flammable items and use stable holders.
What is the safest light in a power outage?
Flashlights, headlamps and battery or rechargeable LED lanterns, since they have no open flame.
How long can a power station run LED lights?
About 5 W per lantern is typical. Five lanterns (25 W) would run roughly 35 hours on a 1,024Wh unit at 85% usable capacity, as a calculated estimate.
Do I need spare batteries?
Yes. Keep spare batteries for flashlights and radios, or a charged power bank for USB-rechargeable lights.
Should I use a gas lantern indoors?
Fuel-burning lanterns create fire and carbon monoxide risks indoors. See our carbon monoxide guide before using any fuel-burning device.
