Emergency lighting for your home during a power cut can help you move around safely, find important items and carry on with basic tasks when the lights go out. Although we often associate emergency lighting with public buildings, commercial premises or communal areas, it is also worth thinking about what lighting options we have available inside our homes.
In certain buildings and public spaces, emergency lighting must meet specific technical requirements. Regulations in each country cover aspects such as automatic activation, minimum operating time, illumination levels, luminaire positioning and the type of installation. Its purpose is to mark exits, make evacuation easier and ensure that potential obstacles and safety equipment remain visible.
A blackout can happen when you least expect it. A lift or an Underground carriage are probably not the best places to be when the power suddenly goes out.
But what if the power cut happens while you are at home? Although your home is a familiar and generally comfortable environment, it is still worth having a basic lighting solution available in case the electricity supply is interrupted for several hours. Let’s look at the main emergency lighting options for your home during a power cut.

Emergency lighting today
Emergency lighting in places as varied as nightclubs, hospitals, stations, car parks and road tunnels is governed by specific regulations. The requirements are not identical in every case, as they depend on how the space is used and the risks involved.
In workplaces with particular hazards, equipment and installations may need to withstand far more demanding conditions.
Although requirements vary depending on the country and type of installation, some of the factors that may be regulated include:
- Automatic activation when the normal lighting fails.
- Minimum operating time in hours.
- Illuminance levels measured in lux.
- Uniformity of illumination.
- Position and type of installation.
- Inspection, testing and maintenance requirements.
- Compliance with the standards applicable to the product.
Other factors, such as the IP rating, operating temperature range or the presence of an automatic testing system, may be relevant for certain environments or products, but they do not form a universal checklist that applies to every emergency luminaire.
The possibility of power cuts at home
Inside a private home, there is generally no equivalent requirement to install emergency luminaires. However, this does not mean that emergency lighting cannot be compulsory in certain communal areas, car parks, stairwells or escape routes within residential buildings.
Would it still make sense to have an alternative source of light? That depends on the needs of each household, but the fact that power cuts may be uncommon does not mean they cannot happen.
A blackout can have many different causes, including a local fault, maintenance work, severe weather or a wider issue affecting the electricity network.
Emergency lighting options for your home during a power cut
If the power goes out at home, each household can decide whether it makes sense to keep something available to provide a minimum level of lighting. These are some of the main options.
Candles
They are probably the most traditional option. Candles are easy to use, familiar to everyone and found in many homes. Who does not have a few birthday candles or candles kept for a special occasion? A candle can provide a small amount of light when the electricity supply fails.
How long they last and how much light they provide depend on their size, material and type. In general, they only light a limited area and may not provide enough light to move around comfortably or illuminate an entire room for several hours.
That said, they should be kept away from flammable materials and out of reach of children and pets. Because they use an open flame, candles should always be handled carefully and never left burning unattended.
Paraffin lamps
Paraffin lamps can operate independently of the electricity grid as long as fuel is available. Although they are still used in some countries, they are not generally a recommended option for indoor use.
This is because burning paraffin can release pollutants into the home, which can be particularly harmful in enclosed or poorly ventilated spaces. These lamps also rely on fuel and an open flame, so they carry a risk of fire and burns.
Torches
Torches are a very practical option, provided you can find them quickly when you need them and they have working batteries or a charged rechargeable battery.
Many people keep a torch at home for walking, DIY jobs or situations where they need to illuminate a specific area. The beam allows you to direct the light exactly where it is needed, although it does not always distribute light evenly across an entire room.
Rechargeable lamps
Advances in batteries, LED technology and control electronics have expanded the possibilities of rechargeable lamps. Today, it is possible to find battery-powered lamps that fit naturally into everyday home use and can also provide light during a power cut.
A rechargeable lamp can provide more ambient lighting than a torch and can be placed on a table or carried between rooms. Its operating time will depend on the specific characteristics of the product, the selected brightness level, the condition of the battery and its state of charge.
| Option | Pros | Cons |
| 🕯️ Candles | Cheap, easy to use and commonly found at home. | Limited light, limited burn time and a fire risk due to the open flame. |
| 🏮 Paraffin lamps | Work without electricity and can provide long operating times. | Require fuel, produce pollutants and carry a risk of fire and burns. |
| 🔦 Torches | Practical, portable and useful for lighting specific areas. | You need to find them quickly and have working batteries or a charged battery; less suitable for lighting a whole room. |
| 💡 Rechargeable lamps | No open flame, portable and well suited to more ambient lighting. | Operating time depends on the battery, brightness level and state of charge. |
LILAK rechargeable lamps as an option
At LILAK, we work on creating rechargeable battery-powered lamps for the home, designed to fit naturally into everyday living spaces while also providing a source of light when the electricity supply fails.
The idea is to make the lamp part of everyday life and easy to find when needed, rather than something that stays hidden away in a cupboard for long periods. As with any rechargeable lamp, its actual availability and operating time will depend on the battery’s state of charge and the technical characteristics of the specific model.
Frequently asked questions about emergency lights for your home
Is a rechargeable lamp the same as an emergency light?
Not necessarily. A rechargeable lamp can be used as a backup source of light during a power cut, but it should only be considered an emergency luminaire if it has been designed for that purpose and meets the relevant requirements.
Both types of product can use batteries, but they do not necessarily perform the same functions or have to meet the same technical requirements.
What is the safest way to light a home during a power cut?
In general, a torch or rechargeable lamp in good condition will usually present fewer risks indoors than a candle or paraffin lamp because it does not require an open flame or fuel.
Even so, any device should always be used and charged in accordance with the manufacturer’s instructions.
How long does a rechargeable lamp last during a power cut?
It depends on the model, the selected brightness level, the amount of energy stored and the condition of the battery. As a general rule, using a higher brightness level will reduce the operating time.
To get a realistic idea of how long a lamp will last, check the operating time stated for each brightness level in the product specifications.
Conclusion: emergency lighting options for your home
Emergency lighting is regulated in certain buildings and spaces to support evacuation, reduce the risk of panic and ensure that exits, obstacles and safety equipment remain visible.
Inside private homes, there is generally no equivalent requirement, but having an alternative source of light can still be useful during a power cut.
There are traditional options, such as candles and paraffin lamps, as well as more common solutions such as torches. Rechargeable lamps provide another alternative that can be incorporated into everyday use while offering wider illumination, provided the battery is charged.
Being prepared does not mean turning your home into an emergency installation. It simply means having a safe, charged and easy-to-find source of light available when you actually need it.
