Choosing the Right Flashlight for Emergencies

In an emergency, the right flashlight can be your best ally. Flashlights come primarily in two types: rechargeable and battery-operated, each with its own set of advantages.

Rechargeable Flashlights: These flashlights are eco-friendly and cost-effective over time, as they don't require constant purchases of disposable batteries.

Ideal for those who plan ahead, rechargeable models ensure you always have a light source ready as long as you maintain their charge cycle. They are particularly valuable in situations where you can anticipate power outages, such as storm seasons, allowing for pre-charging as part of your preparedness routine.

Battery-Operated Flashlights: Often powered by AA or CR123A batteries, these flashlights are excellent for immediate use, especially in spontaneous emergency situations where recharging may not be an option.

They are also beneficial for storing in multiple locations, such as in car glove compartments or emergency kits, since they do not require electricity to maintain their readiness. The key is to store extra batteries and check them periodically for replacements due to expiration.

Since lithium AA (1.5V) and CR123A (3V) batteries have a storage life of 10+ years, these batteries are ideal for powering flashlights and other devices after very long storage.

Hint: if the device doesn't operate as it should after few years of storage, take the batteries out and then put them back in - a thin layer of corrosion may prevent the device to operate as it should. Taking the batteries out and in, or light nudge is usually more than enough to remove that thin layer of corrosion.

When choosing a flashlight, consider the typical emergencies you might face and balance that with the practicality of keeping the device charged or stocked with batteries.

Assess the durability, brightness settings (lumens), and additional features like water resistance or multiple light modes that could enhance their usefulness during emergencies.
