LED Lantern vs. Flashlight: Best Lighting for a Power Outage
A lantern lights a whole room, which matters more than a flashlight's narrow beam for actually living through a multi-hour outage — cooking, finding things, general movement around the house.
Rechargeable lanterns with a battery bank or hand-crank backup avoid the disposable-battery restocking problem of flashlights, and many run 12+ hours on a single charge — well past a typical overnight outage.
Avoid candles where possible — they're a real fire risk during an already-stressful outage, especially with kids or pets in the house.
