Build a Blackout Lighting Plan That Works Immediately

Do not rely on one light or your phone. Use automatic power-failure lights to reveal the route immediately, then keep a charged flashlight, headlamp or lantern within reach of each person for movement and longer use. During an outage, the CPSC recommends battery-powered flashlights or lanterns instead of candles because an open flame adds a fire hazard (CPSC).

Check the three layers; the result identifies gaps in your lighting plan.

Need	Best Lighting Layer	Placement
See immediately	Automatic plug-in light	Bedroom-to-exit routes, stairs and hall turns
Move or inspect a problem	Flashlight or headlamp	At each bed and in a central location
Light an occupied room	Portable lantern	Main occupied room
Use another way out	Portable light and alternate route	Planned from every bedroom

Automatic Lights Cover the First Seconds

A plug-in light designed for power failures normally charges its battery while connected and switches on when outlet power disappears. Its main advantage is not necessarily high output or long runtime: nobody has to locate it in the dark.

Check the instructions for the specific model before buying or placing it. Confirm that it switches on automatically, how it must be charged and the runtime claimed by its manufacturer. Features and operating procedures are model-specific.

Place automatic lights where sudden darkness creates the greatest navigation risk:

• between sleeping areas and the nearest exit;
• near the top and bottom of stairs;
• at hallway turns or changes in floor level;
• near an exit door, provided the light does not take an outlet needed by medical or other essential equipment.

The beam should reveal stair edges, obstacles and the direction of travel. Do not hide the unit behind furniture, aim glare directly into someone’s eyes or put a protruding plug-in model where feet or moving objects can strike it.

A consumer plug-in light is not automatically equivalent to code-required emergency lighting in an apartment common area or another regulated space. UL explains that standards including UL 924 cover emergency luminaires, exit signs, pathway markings, controls and supporting power (UL Solutions).

Tenants should report failed corridor or stairwell emergency lighting to building management. Personal lights provide another layer inside the home; they are not a substitute for required building equipment.

Portable Lights Carry the Rest of the Outage

Ready.gov advises having a flashlight for every household member (Ready.gov). Keep one within reach of every bed so nobody has to cross a dark room to find the household supply.

A headlamp leaves both hands free on stairs or while helping another person. A flashlight is useful for inspecting a specific area, while a lantern spreads light across an occupied room. Store an additional portable light in the main living area, but not beside the automatic light. A blocked location should not take both layers out of reach.

Treat advertised runtime as an estimate rather than a guarantee. Brightness setting, battery condition, temperature and state of charge can change the result. If the manufacturer provides battery energy in watt-hours and the light’s draw in watts at the selected setting, watt-hours ÷ watts gives the ideal runtime in hours. Actual runtime may be shorter because the full rated energy may not be usable. See battery charge and usable energy for the calculation.

For lights that use replaceable cells, keep a matching spare set in its package and inspect installed cells for leakage. Charge rechargeable lights only with equipment the manufacturer allows.

Check the exact brand and model in the CPSC recall database. Recalls can be limited to particular models and date codes. In January 2026, CPSC recalled about 4,100 Energizer BGAAL9 lanterns with a June 2024 date code because their lithium-ion batteries could overheat (CPSC recall). That recall does not establish a defect in other Energizer models or date codes.

Blackout Lights Should Follow Both Exit Routes

After dark, inspect the path between every sleeping area and two possible exits. The U.S. Fire Administration says a home fire escape plan should provide two ways out of every room and keep doors and windows on those routes unblocked (USFA). Blackout lighting should support that plan rather than replace it.

Remove shoes, charging cords, stools and other trip hazards from the routes. Place lights so they reveal hallway turns, steps and exit doors instead of merely brightening the center of a room.

In a high-rise, know where all exit stairs are. During a fire, USFA says to use the stairs rather than an elevator unless the fire department directs otherwise.

A routine blackout and a fire alarm require different decisions. During an ordinary outage, use the illuminated route carefully. If there is smoke, fire, a hot door or an evacuation order, use the safe alternate route and leave. Do not follow a familiar lit path into danger.

Test the Whole Setup Before an Outage

Follow each product manual’s testing and charging schedule. Before forecast severe weather, test the lights as a connected system rather than checking only whether individual bulbs turn on.

1. Confirm each automatic light activates using its test control or the procedure specified by its manufacturer.
2. Charge portable lights, then run them briefly at the brightness setting you expect to use.
3. Confirm every person can reach a working portable light from bed.
4. Walk both planned exit routes in low light and remove any new obstacles.
5. Check that spare replaceable batteries match the lights that need them.

Stop using a rechargeable light that is swollen, cracked, damaged or unusually hot. Follow the manufacturer’s or local hazardous-waste guidance for handling it.

Permanently installed or hardwired emergency lighting should be handled by a licensed electrician under applicable local permit and code requirements. Do not improvise wiring during an outage.
