We’ve tested a large number of flashlights from a variety of brands to find the best for an emergency. There are thousands of models of flashlights out there, but we were able to trim the field quickly with some research and quickly recognizing quality gear. Versatility, output, runtime, and battery type were all huge factors that separated out the best flashlights from the rest of the competition. If you want a versatile, quality flashlight for any situation, one of our prepper flashlight recommendations will get it done.

ThruNite cranks it to 11 with the TN12 V6 powering a massive -lumen LED with a mAh rechargeable battery without regard for heat. Some view the hot lens cap when it’s running in Turbo as a drawback, but as long as you are aware that it can get hot, we don’t see it as a big issue. In our runtime and durability tests, the housing dealt with the heat fine and wasn’t near the battery, which would affect charging/discharge. This is also the ‘improved’ version (over the previous pro model), meant to disperse the heat better.
This flashlight has a removable, rechargeable Li-ion battery at 3.6V 12.24 Wh (type ). It charges through an integrated USB-C port, so you won’t need to remove the battery to charge. The battery’s discharge performance is great, giving the light a long runtime even when you run it through the maximum modes as it steps down in lumens.
Specs:
Cycle through the modes with rapid presses on the main switch, or by holding the switch. Press the separate tail switch for a burst of Turbo (only while pressed), which is great for getting high-output fast or self-strobing. The Strobe mode runs at a high frequency, making it effective and disorienting at 560 lumens.
The dual-sided clip is large and effective for pockets or MOLLE, and it is removable if you prefer. The handle knurling is adequate in wet and muddy conditions, and the rubber USB-C charge port cover held up during testing. I could see the rubber cover as a potential issue down the road, but it’s not a hanging-style cover- it is fully attached on one side.
The ThruNite TN12 Pro Flashlight is the best prepper flashlight for survival kits and bug out bags when you need to balance performance and value.
The GearLight S punches way above its weight class. For ~$15, you get an adjustable zoom LED flashlight that generates up to 800 lumens with a max throw of 300 yards. The aluminum casing is 6 inches long and makes it lightweight- the flashlight weighs just 5 ounces (without the holster).
The flashlight is not water-tight, but it is close with solid water resistance using o-rings. With regular AA batteries, the output is closer to 400 lumens- but the versatile battery housing for various battery types allows you to pick both power and wide availability. It also lasts at least 10 hours on a set of fresh AAs.
GearLight also produces lanterns and headlamps, but the S is the California company’s workhorse with over 35,000 online reviews. You could find a better flashlight on the market, but not for this value. If you need more runtime, output, or throw distance you can always upgrade- but you will find that the GearLight S LED Flashlight is the best prepper flashlight for survival kits and bug out bags if you’re staying on a tight budget.
Olight has been constantly innovating LED flashlights, tactical attachment lights, headlamps, and more. Their catalog is constantly growing- if it’s a light and it needs to use powerful LEDs they’ll probably end up making it.
The Seeker 4 Pro is one of the toughest lights you will come across. It is completely sealed and waterproof, so it uses a magnetic charging cable that seats to the bottom of the light to charge its mAh rechargeable Lithium Ion battery. The light puts out a whopping lumens thrown 260 meters and can run for 15 days – all of that power in a housing less than 6 inches and less than 8 ounces.
The mountable holster that doubles as a charger is the cherry on top. It’s the detail that pushes the versatility of this light above other contenders. Holstering your light in your bug out vehicle or even in your bag can start recharging it automatically. Olight’s Baton models tried this first, but the charging case was cumbersome. Now we have an open-air holster with USB-C charging coming in and magnet charging going to the light.
Don’t worry about rubber charging ports on this light- it’s completely sealed and IPX8 waterproof. It charges through magnetic induction at the tail, and the battery and brightness indicator lights use ‘microperforation.’ This makes them bright and completely waterproof. It doesn’t use a separate lens- it’s lasered into the mode toggle button.
Pick up the Olight Seeker 4 Pro Flashlight if you are looking for the best of the best.
Our research narrowed the field down to several contenders that we tested: Eveready, Nitecore, Olight, GearLight, Maglite, Streamlight, Surefire, and more. This helped us eliminate flashlights that just weren’t a good value. Finding the best value and a solid budget pick ended up being much more straightforward than our upgrade pick. There were plenty of options at lower price points, but most of them match their low price with low quality. The few exceptions stood out quickly.
At the higher tier (upgrade) prices, there were still plenty of options from well-known quality brands, so features and versatility became more of a factor. Maglite used to be the de-facto flashlight for emergency use but has seemingly been out-innovated by a wide range of competition. The onset of LEDs has flooded the market with competition, and a new set of leading brands has emerged.
The best prepper flashlights have several important features to look for. To compare flashlights with our measurements and metrics, we consolidate those into an overall score by weighing the features.
Below, we break down what each of these means for a great flashlight. When you get the right blend of these, you can find a great flashlight without breaking the bank.
There are plenty of expensive flashlights that are just awesome. If you are a lottery winner, maybe you can stock up on these for all of your kits. For the rest of us, in the real world, we need to consider what we’re actually getting for the price of the flashlight.

A solid, cheap flashlight is an excellent pick for an occasional-use survival kit. Sure, you don’t want some cheap flashlight that will fail you in an emergency, but there is a tipping point where you could easily overpay for a flashlight. That’s why our upgrade pick is small enough to be EDC- if you are shelling out serious money for a flashlight you need to be using it often and getting your money’s worth.
Flashlight performance is the main thing that separates out the garbage from the useful gear. Most times, brightness is measured by the lumen output and throw.
Lumens are a measurement of the light output. Flashlights range from 20 lumens all the way up to the hundreds of thousands now. Flashlights have really gotten brighter over the last several years, but most times this kind of output can drain a battery quickly.
The throw of a flashlight is a factor of the Lumens produced, reflector cone shape, and lens type that affects how far the flashlight beam travels. Some flashlights have a throw beyond 500 yards. Some flashlights have a ‘zoom’ bevel which allows you to change the beam width and throw distance.
The problem is that both of these are difficult to measure and don’t paint a complete picture of brightness- especially lumen output. LEDs are lumen-rated, which is typically what manufacturers list as flashlight lumen output- but the real brightness varies based on cone type, battery type, and LED configuration.
That’s why we use a light trap and light meter to measure brightness. It’s not perfect since it puts the results in Lux (or footcandles)- but it’s a good benchmark for comparing the total light output from these flashlights.
Runtime is a fancy flashlight word for how long it lasts when it is turned on. This is usually directly related to its battery capacity and the lumen output. A good runtime is a few days, and some flashlights can even be on for weeks.
Disregarding ‘firefly’ or ‘moon’ modes that output less than 1 lumen, we ranked the flashlight based on their reasonable runtimes with stock batteries:
Durability covers how well a flashlight can take abuse. Because these are meant for potentially life-altering situations, we need flashlights that can survive through thick and thin.
Manufacturers usually list a few signs signaling how durable a flashlight will be:
There are many ways to make a flashlight more versatile, but here are a few:
There are also specialty flashlights that are excellent for prepping and survival purposes, such as:
Most of these specialty lights were not considered and have reviews of their own in some cases.
Batteries are one of the more nuanced decisions you can make when selecting a prepper flashlight. There are two main routes you can go:
To muddy the discussion even more, you could always go with rechargeable and replaceable batteries, like Eneloop.
The list of emergencies that could make the power go out is almost too long to list. We’ll list a few out anyways:
The list goes on, and these are just the tip of the iceberg. To see all common threats and their matching risk score, you can check out our Threat List. As you can see, the probability and impact of these events are very different, but your survivability for each of them can depend on how prepared you are to bug out.
Flashlights can help you see in the dark, but you can also signal with them and some models can even be used to generate heat. They are versatile tools all on their own, and having some light around during an emergency can even be comforting.
With so many threats with the potential for power outages, flashlights are a well-known preparedness priority. It is pretty hard to get things done in the dark, so a flashlight is just a common-sense tool for emergencies. If that’s not enough for you, the Red Cross, FEMA, and CERT – all these agencies agree that self-sufficient preparedness is important and that every family should have an Emergency Plan that includes kits with flashlights.
Flashlights are a key tool for preparedness and prepping. Everyone can benefit from being able to see in the dark, especially in an emergency.

Choosing the right emergency light can make all the difference when the power goes out. It ensures you stay safe and prepared during unexpected situations. A reliable option, like a dual head emergency light, provides consistent illumination when you need it most. Whether it’s a bulkhead emergency light or an LED emergency light remote head, the right choice keeps your space secure. Stick around for tips to help you pick the perfect one.
When it comes to choosing an emergency light, you’ll find several types to suit different needs. Let’s break them down so you can decide which one works best for you.
LED emergency lights are a popular choice. They’re energy-efficient and last a long time. You’ll notice they provide bright, consistent light, which is perfect during power outages. Plus, they don’t heat up, making them safe to use in any environment. If you want something reliable and cost-effective, LED options are worth considering.
Rechargeable emergency lights are super convenient. You can charge them ahead of time and use them when needed. They’re great for homes, offices, or even camping trips. Many models come with long-lasting batteries, so you won’t have to worry about running out of power quickly.
Exit signs and emergency exit lights are essential for public spaces. They guide people to safety during emergencies. You’ve probably seen them in schools, malls, or theaters. These lights are designed to stay on even when the power goes out, ensuring everyone can find their way out.
Solar-powered emergency lights are eco-friendly and practical. They use sunlight to charge, so you don’t need electricity. These lights are perfect for outdoor use or areas with frequent power outages. They’re a smart choice if you want to reduce your carbon footprint.
Portable emergency lights are lightweight and easy to carry. You can take them anywhere, whether it’s a camping trip or a roadside emergency. They’re versatile and come in various designs, from flashlights to lanterns. If you need flexibility, portable options are ideal.
When choosing the best emergency light, you’ll want to keep a few important factors in mind. These considerations will help you make a smart and informed decision.
First, check if the emergency light meets your local safety standards. Many areas have specific rules for emergency lighting, especially in public spaces. Ignoring these regulations could lead to fines or safety risks. Always look for certifications or labels that confirm compliance.
Your budget plays a big role in your choice. Emergency lights come in a wide price range, so decide how much you’re willing to spend. While cheaper options might save money upfront, they may not last as long. Investing in a quality light can save you from frequent replacements.
Energy-efficient lights are a win-win. They save you money on electricity and are better for the environment. LED emergency lights, for example, use less power while providing bright illumination. Look for models with energy-saving features.
A reliable emergency light should have a long battery life. You don’t want it dying in the middle of a blackout. Rechargeable options are great, but check how long they take to charge. Some even offer solar charging, which is super handy.
Durability matters, especially if you’re using the light outdoors or in tough conditions. Look for sturdy materials like aluminum or high-quality plastic. A well-built light can handle drops, weather, and wear over time.
Finally, consider how bright the light is. You’ll want enough illumination to see clearly during an emergency. Check the lumens rating to compare brightness levels. Some lights even let you adjust the intensity, which is a nice bonus.
Start by thinking about where you’ll use the emergency light. Is it for your home, office, or outdoor adventures? Each setting has unique power needs. For example, a small flashlight might work for camping, but a larger, wall-mounted light is better for a workspace. Also, consider how often you experience power outages. If they’re frequent, you’ll need a light with a long-lasting battery or solar charging capabilities.
Not all emergency lights are created equal. Some are designed for specific purposes. If you need a light for guiding people during emergencies, exit signs or emergency exit lights are ideal. For personal use, rechargeable or portable options might be better. Match the type of light to your specific needs to get the best results.
If you plan to move the light around or use it outdoors, portability is key. Look for lightweight designs that are easy to carry. Weather resistance is another important factor. A durable, waterproof light can handle rain, snow, or extreme temperatures without failing.
Automatic activation can be a lifesaver. These lights turn on instantly when the power goes out, so you’re never left in the dark. This feature is especially useful in homes or offices where safety is a priority. Check the product description to see if this feature is included.
A good warranty shows that the manufacturer stands behind their product. Look for emergency lights with at least a one-year warranty. Also, check if the company offers reliable after-sales support. This ensures you can get help if something goes wrong or if you need replacement parts.
Testing your emergency lights regularly is crucial. You don’t want to discover they’re not working during a power outage. Regular checks ensure the lights are ready when you need them most. Many local regulations also require periodic testing, especially in public spaces. By staying on top of this, you’ll avoid fines and keep everyone safe.
Tip: Set a reminder on your or calendar to test your emergency lights monthly. It’s a quick task that can save you a lot of trouble later.
Maintaining your emergency lights doesn’t have to be complicated. Start by cleaning the light covers. Dust and dirt can reduce brightness. Use a soft cloth and mild cleaner for this. Next, check the batteries. If they’re rechargeable, make sure they’re holding a charge. For plug-in models, inspect the power cords for any damage.
You should also test the light’s functionality. Turn off the main power supply to see if the light activates automatically. If it doesn’t, there might be an issue with the wiring or battery.
Sometimes, you’ll need an expert to step in. If your emergency lights are part of a larger system, like in a commercial building, professional inspections are a must. They’ll check for compliance with safety standards and fix any technical issues. Hire a pro if you notice flickering lights, unusual noises, or if the system fails during a test.
Note: Hiring a professional once a year can help you catch problems early and extend the life of your emergency lights.
Batteries don’t last forever. If your emergency light isn’t holding a charge, it’s time for a replacement. Check the user manual for the correct battery type. For LED lights, you might also need to replace the bulbs after a few years. Always use compatible parts to avoid damaging the unit.
Reminder: Keep spare batteries on hand, especially if you live in an area with frequent power outages. You’ll thank yourself later!
Choosing the right emergency light keeps you safe and prepared. You’ve learned about the types, key factors, and practical tips to make the best choice. Regular maintenance ensures your light works when you need it most. Don’t wait—take action today and invest in a reliable option for peace of mind.
It depends on your needs. Rechargeable LED lights are great for homes. They’re energy-efficient, long-lasting, and provide bright illumination during power outages.
You should test them monthly. Regular testing ensures they work during emergencies. Set a reminder to make this a quick and easy habit.
Tip: Testing takes just a few minutes but can save you from unexpected failures.
Yes, but they need sunlight to charge. Place them near windows during the day. For consistent indoor use, consider rechargeable or plug-in options instead.
