Ready.gov's advice is short: have flashlights for every household member. In practice, three kinds of light do three different jobs, and most homes need a little of each rather than a drawer full of one kind.

What each light is for

Light Best job Strengths Weaknesses
Headlamp Cooking, caring for kids or pets, moving around, anything needing two hands Hands-free, points where you look, usually long runtime on low Not great for lighting a whole room
Lantern Lighting the warm room so people can read, eat, play cards Even 360° light, reduces "spotlight in the eyes" Bulkier; larger ones use more power
Flashlight Checking the breaker box, going outside, signaling Long throw, easy to hand someone Ties up one hand
Candle Ambience only Cheap Fire risk (NFPA), dim, no use in a draft

How to read a light's spec sheet

Lumen numbers sell lights, but runtime at a useful setting decides whether you have light at 3 a.m. on night two. When you compare models, check:

  1. Runtime per mode (low, medium, high). Manufacturers often list runtime on low; that is the mode you will use most.
  2. Battery type. Standard AA/AAA is easiest to resupply; built-in rechargeable needs a charging plan; some lights accept both.
  3. Charging port. USB-C means you can charge from the same power banks as your phone.
  4. Red light mode on headlamps preserves night vision and does not wake sleepers.
  5. Water resistance rating (an IPX number) if you will use it outdoors in snow.
  6. Lowest mode brightness. A very low "moonlight" mode can stretch batteries for days.

A simple plan by household

Store lights with batteries removed if the manual recommends it, in one known place, with spares of the right size taped to the box.

FAQ

Are candles okay for a power outage?

Ready.gov recommends flashlights for every household member, and NFPA notes candle fire risks. Battery LED lights are safer and brighter, especially around kids and pets.

Rechargeable or disposable batteries for emergency lights?

Alkaline AA/AAA batteries store well and are easy to find. Rechargeable lights are cheaper long-term but must be kept charged. A mix, with lights that accept standard AA batteries as a backup, is the most resilient.

How many lumens do I need?

For walking around a dark house, a modest setting is plenty and saves battery. Brighter modes are useful outdoors. Runtime at the setting you will actually use matters more than the maximum lumen number.
