Power cuts can happen without warning, and finding yourself without a light source to help you move around, even in your own home, can make everyday tasks difficult. That’s why having a reliable source of emergency lighting at home is worth considering. Emergency lighting is required in certain communal areas of buildings, but individual homes don’t usually have an equivalent system installed.<\/p>\n\n\n\n

If you’re thinking of buying a battery-powered lamp as a source of emergency lighting for your home, there are several common mistakes worth avoiding. Battery life, automatic activation and the ability to replace the battery are all important factors to consider. These features can make a significant difference to how useful a cordless lamp is during a power cut, particularly if the electricity is off for an extended period.<\/p>\n\n\n\n

Mistake 1. Choosing a Light Without Checking Its Actual Battery Life<\/h2>\n\n\n\n

One of the most important features of a portable lamp is its battery, particularly how long it can keep the light running<\/a>. However, battery life doesn’t depend on the battery alone. The efficiency of the electronics and the selected brightness setting also affect how long the lamp can operate. It’s therefore worth checking the operating time stated in the manufacturer’s technical specifications. Battery life varies considerably between models, so choosing a lamp that provides enough hours of lighting for your intended use during a power cut is essential.<\/p>\n\n\n\n

\n

The available brightness settings are another factor affecting the actual battery life of a battery-powered lamp. With the same lamp, selecting a higher brightness level will generally reduce its operating time. For this reason, it’s important to consider how much light you need<\/a> and how your chosen brightness setting affects the battery life of your wireless lamp.<\/p>\n\n\n\n

Mistake 2. Confusing Cordless Lighting with Automatic Emergency Activation<\/h2>\n\n\n\n

Emergency lighting systems required by building regulations in certain buildings and premises must activate automatically when the normal lighting supply fails. Their purpose is to support safe evacuation by keeping exits, escape routes and certain safety equipment visible.<\/p>\n\n\n\n

If you have a rechargeable table lamp to provide lighting during a possible power cut<\/a>, it’s important to remember that it won’t necessarily work in the same way. A cordless lamp may be connected to the mains to operate or recharge its battery, but that doesn’t mean it will automatically switch on if the electricity supply fails while the lamp is switched off and plugged in. To do this, the lamp needs a dedicated system that can detect the interruption and activate the light.<\/p>\n\n\n\n

Luminaires designed for emergency lighting installations covered by building regulations must meet specific technical requirements that don’t necessarily apply to every battery-powered lamp. So, if you want a light that switches on automatically when the mains supply fails, you need to check that it includes this feature. If the device is also intended to form part of a legally required emergency lighting installation, you must ensure that it meets the relevant regulatory requirements.<\/p>\n\n\n\n

Mistake 3. Overlooking How the Battery Is Charged or Replaced<\/h2>\n\n\n\n

Many of the components in a portable lamp have a limited lifespan and won’t last forever. That’s why it’s worth considering whether they can be replaced. In a battery-powered device, this is particularly important when it comes to the battery itself<\/a>. Many of these lamps include rechargeable batteries, but can those batteries be replaced when their capacity deteriorates through use and ageing?<\/p>\n\n\n\n

Being able to replace a battery when it reaches the end of its useful life is a valuable way to extend the lifespan of the lamp. Some designs make this straightforward, with easy access to the battery so users can replace it themselves. Other battery operated lamps may require the assistance of a qualified technician.<\/p>\n\n\n\n

In either case, it’s important to follow the manufacturer’s instructions and use only batteries that are compatible with the device’s specifications.<\/p>\n\n\n\n
