If you don’t use your flashlight often, just charge it every few months. I have lights that have sat for more than a year without charging that fire right up, so as long as you don’t leave empty, you can expect a quality light to work during your next power outage. If a hurricane is on the way, grab a portable battery to keep all your electronics topped up.

While this is a high-end flashlight, it’s absolutely worth the price for those who need a powerful, reliable flashlight with the potential to hold up to extremes.

A budget flashlight needs to have more than just a nice price. It must also be durable, so you won’t have to run out and buy another in a few months. I put the Archer through rigorous testing, including submersion and drop testing. It came through with flying colors, barely edging out the competition with the Coast G32. I loved the simple interface — particularly the side button to scroll through brightness settings.

Beyond user experience, the runtime is phenomenal. With the new PD36R PRO in Eco (30 lumens) mode, you can achieve a solid 42 hours of runtime. If runtime is your primary concern, the non-PRO version of this light has a much longer runtime, but lower overall output.

I strongly prefer USB-C charging over all other methods. It’s a nearly universal cable type, and you probably have many in your home already. However, I will concede there are advantages to some magnetic charging styles, such as those used by Olight. These magnetic charging cables enable excellent water and dust proofing and work quickly — just don’t lose or forget the cable.

Yes, LED flashlights do get warm if they’re pushed hard enough. For many flashlights, this is a sign the heat sink is working, moving heat away from the delicate electronics inside.

Overall, the EDC27 is an incredible new flashlight. I haven’t had enough time testing it to say it will outperform our current top pick, but it certainly should give Fenix a run for its money.

Over $90, you should get a high-quality CR123A, 18650, or other purpose-built battery. The light should have a regulated output and temperature management and a great user interface. If you use a flashlight regularly, it’s worth the investment to step into good flashlights. My top choice is the Fenix PD36R PRO ($120), a versatile light with 2,800 lumens on its max setting, a 380-meter beam range, and my favorite user interface. The mighty Olight Prowess ($140) blasts an impressive 5,000 lumens if it’s maximum brightness you’re looking for.

After these tests, and more importantly, I and other testers put all these flashlights through real-world, outdoor use. We use them camping. All of the selections have ridden in the center console of my truck for at least a couple of weeks. Most of them have been in a rainstorm.

With the flick of a switch, the Prowess becomes a lantern, projecting a warm light, redirected toward the base of the flashlight. While resting in its detachable charging base, the light can sit on any flat surface, producing a cozy glow to read or work by. In its lowest moonlight setting, it can go for a continuous 20 days.

I’m a flashlight buff, and during my more than 13 years at GearJunkie, I have used, abused, and tested countless flashlights. For this guide, I chose to test small, versatile flashlights primarily for outdoor and general use. Each light in our top choices has survived drop testing, water submersion, and longevity testing. Most importantly, I vet them through real-world use. Read on to learn more about how I chose the test lights, how I test them, and why you should trust me.

Yes, headlamps are many people’s go-to lighting solution. But the best flashlights offer more power and longer-lasting batteries and will shine wherever you want, not just where your head points.

Finally, the light has an easy-to-read OLED display. It reads run time and current lumen output. This takes the guesswork out of recharging the battery and lets the user know exactly what they can expect the light to do.

It works extremely well in the field. We’ve used it to find our way out of the woods while bushwhacking during elk hunts in the Rocky Mountains and appreciated the ability to scan far away hillsides for trails and landmarks with the max 1,000 lumens and 180 meters of throw.

Next, I consider water resistance and durability. All the lights tested here survived at least a 5-foot drop test onto concrete and submersion in water.

However, if you lose the base and the MCC3 cable (they’ve got to be in a drawer somewhere with all those batteries), then you can’t charge with the ubiquitous USB-C, and you’ll need to buy another MCC3 cable, and the light is already on the pricey side. The USB-C is the current standard and should be the default method

A quick look at the specs reveals class-leading numbers. A top output of 3,000 lumens and a 200m range will serve all but the most dire search and rescue, hunting, or tactical needs. And a run time of 37 hours on low provides a good, long life for the vast majority of uses.

I take all this information and experience and compile the best advice for you. Over the years I’ve tested about 50 flashlights specifically for this buyer’s guide, selected from hundreds pitched to me by brands and examined at events like SHOT Show and the Outdoor Retailer convention. I aim to give you the same advice I give my best friends.

This is relevant in the reading room, because if the screen and the ambient light are quite different (either brighter or darker) your vision will constantly be readjusting between the ambient light and the screen each time you look away from the screen. Despite your eyes adjusting to the screen, as soon as you look away to a brightly lit wall, light or object – your eyes will begin readjusting to this change in contrast. So, when you look back to your screen you will no longer have optimal vision until several minutes have passed.

What follows is my best advice for buying flashlights, the same advice I’d share with friends and family. So, let’s get you the best flashlight for your needs.

1,000 to 2,000 lumens is plenty bright for an EDC. That should give you enough juice to see objects 200 to 300 yards away. Our top choice for everyday carry is the Nitecore EDC27.

From $30 to $90, folks can expect more in terms of quality batteries, LEDs, and reflectors. A lot of good flashlights are available at this price range, especially if you don’t need a lot of lumens. Both the NITECORE EDC27 ($90) and the NITECORE EDC33 ($70) fall solidly in this category with their lithium Ion Batteries and 230+ meters of throw.

The P20IX punches through the darkness with 4,000 lumens on turbo mode for up to 30 minutes. That’s enough to light up objects 250 yards away, so it should be high on your list for performance alone. More importantly, it has four continuous and strobe modes, ranging all the way down to the 2-lumen ultralow mode that provides light for up to 350 hours.

The core of your light use will probably be in the 300-1,000 lumen range. This gives you plenty of light at normal ranges up to around 50 feet. Tight beam patterns can extend this range significantly, but the lights included here have more useful, wider light beams.

Modern LED flashlights vary in the quality of their color rendering, meaning you can see color better with some higher-end lights. The best flashlights on the market should always give you a colorized, realistic view.

For most campers, anything over 1,000 lumens is overkill. You’ll often find yourself using much lower settings, especially around camp. So all the lights included have excellent low-power settings. From 30 lumens on my top choice to one-lumen “firefly” modes, these lower settings sip electricity.

Those are pretty wild specs for a flashlight that weighs just 8.43 ounces and measures less than 6 inches in length. It runs on a 5,000mAh rechargeable battery. You can recharge it anywhere you have a 12-volt USB outlet or recharger. It comes in three additional colors.

Finally, bigger numbers over 2,000 lumens are fabulous when you need them. Whether trying to spot far-off objects or searching for a lost item or drop of blood while hunting, powerful lights have a valuable place in the outdoors. You’ll rarely use high power settings often, but be very thankful for them when you need them.

One final note on AA and AAA batteries. Some folks argue that it is easier to replace batteries in the field than to charge them. Our testers have carried small battery chargers on many adventures, and they work great with flashlights for long trips. For trips over a week or two in length, though, disposable batteries still have an edge.

Eyes adapt to the brightness level of one’s environment. If adapted to a dark tunnel, suddenly exiting will cause you to be momentarily blinded with white. However after several minutes the eyes will re-adapt to this brighter environment.

The Ledlenser MT10 rechargeable flashlight ($90) competes well with the Fenix above, and on paper, it in some ways outshines the competition. The specs put these two top flashlight choices in similar categories, and I expect users will love them both.

Best spotlight for long distance

AA and AAA lights are OK for budget flashlights, but they are wasteful and not as good. Further, they require you to keep batteries on hand. It’s much easier to plug your light into a USB-C cable and keep it fresh than to buy new batteries from the store. And you’ll get better performance than from throw-away or even rechargeable AA or AAA batteries.

SPIE 6146, Medical Imaging 2006: Image Perception, Observer Performance, and Technology Assessment, 61460W (17 March 2006); doi: 10.1117/12.660137; https://doi.org/10.1117/12.660137

Our testers also loved the simple, common USB-C connection for fast recharging and the multicolor battery level indicator. Top it off with a glow-in-the-dark bezel that makes it easy to find in a center console in the dark, and you’re looking at a lot of flashlight for not much money.

Next, rechargeable flashlights generally have a charging port or system built in. As you can see with our choices, our favorite flashlights today use USB-C charging. This is quickly becoming the industry standard as it is much faster than micro-USB charging. And unlike magnetic charging systems (or other proprietary chargers), you can easily find a USB-C cable anywhere and likely own several already.

Now, for the negatives of a small, powerful flashlight. First, the battery is not removable. That means if the battery gets weak, the flashlight won’t perform as well. Given the quality of Nitecore batteries, I imagine you’ll get a long lifespan of multiple years from the light, but it’s worth considering, and a significant drawback for some buyers. Next, note that this light will get very hot very quickly in high-power modes. So if you need a powerful beam for longer than a few seconds at a time, get something bigger.

So, how do I test flashlights? First, I use them in controlled environments, measuring runtime and brightness compared to claimed numbers. I put them on a scale to check the weights. I submerse them in water and drop them onto concrete.

First and foremost, you’ll want a small flashlight that’ll fit in your pocket, clip to your belt, or fit in your daypack. After that, look for a flashlight with good brightness, long battery life, and easy operation.

Brightest 12v spotlight

The most major way that ambient light can reduce contrast is by affecting the eyes’ ability to adapt to a certain level of light. At any one time, the human eye can detect a contrast ratio of 1000, however this ratio is not definite, but rather relative. For example when in a dim tunnel you will be able to see most things clearly. When you suddenly exit into the sunshine outside, most objects will be brighter than the bright objects in the tunnel, so they will appear as a bright white to your vision. This is because in the dim tunnel, the darkest objects become ‘black’ to your perception, and the bright objects – for example the dim light coming the ceiling – become ‘white’ to your perception. Anything brighter than the dim light would automatically register as ‘white’ to your vision – thus when you step outside you will suddenly be blinded because the majority of objects will be brighter than anything in the tunnel.

Failure isn’t an option when it comes to choosing a satellite messenger. When you absolutely need to get the word out, here are the best sat messaging devices in 2024.

With a maximum output of 2,250 lumens (and the ability to project it a whopping 500 m), the Warrior X Pro ($120) packs a heck of a punch. For most people, that level of output is overkill. But for those who need to sweep large expanses of nighttime terrain (like search-and-rescue personnel), this kind of power can come in handy.

Blackfire, a newer division of Klein Tools, is making some nice flashlights these days. Overall, the BBM6412 ($35) is an excellent upgrade to our previous top flashlight for mechanics.

Langer, “Medical Imaging Displays and Their Use in Image Interpretation”, RadioGraphics 2013, vol. 33, p. 275-290; doi: 10.1148/rg.331125096;  https://doi.org/10.1148/rg.331125096

For the money, the G32 is a solid, well-made flashlight that impressed me in use outdoors and around the house. It’s a bit long for EDC use but will work great around the campsite or at home. And, if you want to upgrade it, Coast offers its ZX555 ZITHION-X rechargeable battery (not included).

When viewing medical images, one of the most important factors for accurate diagnosis is contrast. The higher the contrast, the more differences in shades our eyes are able to see. Most medical monitors aim to provide high contrast screens, which is certainly the first and most important way to increase contrast. But even with a high contrast monitor, one little thing can greatly reduce contrast: ambient light.

One thing I love about the MT10 over the Fenix PD36R is the Ledlenser Advanced Focus System. This simply means you can adjust between a broad floodlight and a long-distance beam in an instant. Simply press the front bezel forward, and the light focuses tighter and tighter.

It runs on a rechargeable battery that powers four CREE XP-L2 V6 LEDs. This setup provides exceptional versatility for everyone from campers and hunters to search-and-rescue and tactical uses. The user interface is great, providing easy access to toggle between modes (like its turbo output and strobe mode) through a dedicated button separate from the rear tail switch.

In a room where the ambient light is greatly different to the screen, every time you move your eyes from the screen to another location, your pupils will either dilate (if the ambient lighting is less) or contract (if the ambient light is greater). This constant dilation and contraction tires the muscles in your eye – leading to eye fatigue. This can also increase the amount of time that is needed for your eyes to adjust to a new setting.

That said, the new version shaves half an ounce and half an inch off the previous model, coming in at 4.06 ounces and 5.57 inches long. So it’s edging closer and closer to a pocket-friendly size.

The Nitecore EDC33 ($70) is a new light for 2024, and it’s incredibly powerful yet very small. For context, this little light will fit in the palm of your hand and weighs a scant 4.48 ounces. It clips to the inside of your pocket, where it doesn’t take up very much real estate. But pull it out and push the tail switch, and wowsers!

If you prefer the lighting control mounted on the body of the light, the standard PD36R is still available. But I suspect most users will love the upgraded PRO model.

The following were previously among our primary buying guide choices. This segment will change as testing continues, with new models coming quarterly.

It’s slightly larger than our winner from Fenix, however, so it’s less suitable for hikers, hunters, or others who value lightweight and small size.

As a philosophy, EDC is built on utility and being prepared for anything. In this case, it represents a flashlight you carry every day with you in case you ever need light in a dark environment.

The quality of human vision is incredibly varied – depending on environmental factors as mentioned earlier, and also on physiological factors. Eye fatigue – apart from being uncomfortable – can also temporarily degrade one’s vision. Having optimal vision is vital in radiology, so it’s important to reduce any eye fatigue – and ambient light can have a large effect on this.

However these can be minimized by using anti-reflective coatings on the screen, and positioning the monitor in such a way that light does not directly reflect onto the screen.

For casual users (occasional camping trips and short bursts of high-output modes), that should amount to months between charges. Our tester has gone more than 2 months without recharging this flashlight with regular usage.

Flashlight users want easy control of the illumination their lights produce. The interface — the buttons and switches that control the light source — is an important consideration.

As noted above, our team prefers rechargeable batteries in most situations. Most rechargeable batteries, such as the 21700 rechargeable Li-ion battery included in the Fenix PD36R PRO, offer superior performance to both disposable and rechargeable AA or AAA batteries.

For the record, it takes a long time and impressive performance for a flashlight to earn a spot in this article. I constantly test new flashlights and updates from our favorite brands and update this article many times each year to keep it up to date with the best flashlights available.

For search and rescue personnel, or anyone who needs a reliable tactical flashlight for nighttime scanning, however, this is one of the best flashlights you can buy.

Speaking of charging, this light charges off a micro-USB cable. I love that feature, as it’s a common size and doesn’t require you to carry an oddball cable on trips.

The G32 is a no-frills AA flashlight with two modes, but it provides excellent lighting. Zoomed out, it provides a wide, perfect circle with no halos, thanks to Coast’s Pure Beam focus. Then, zoom the lens for a bright light point with a 134-meter throw. The zoom motion is very simple and smooth. Grab the zooming head by the nice knurling and twist it. It zooms to a hard stop on wide and long throws.

A range of ergonomic issues can also cause eye fatigue. Read ‘How to Create the Ideal Ergonomic, Stress-Free and Work Efficient Environment’ to find out more.

In general it is recommended that the ambient lighting matches the brightness of your screen – which is stated to be 20 to 40 lux when the screen is at a brightness of at least 350 cd/m2 (or 420 cd/m2 for mammography), as per the American College of Radiology guidelines. However the European guidelines for quality assurance in breast cancer screening diagnoses recommends 20 lux or less. One study1 has shown that ambient lighting below 7 lux is too dark, and over 100 lux is too bright, so regardless of which recommendation is followed – ambient light must not be too dark or too bright. Additionally, before beginning work, a radiologist should allow their eyes to adjust for about 15 minutes2 to bring their vision to the optimal level.

You can get exceptional lighting performance, a fantastic user interface, and long, rechargeable battery life from the Fenix PD36R Pro flashlight. It’s my top choice from more than 50 I’ve tested over the past 5 years of maintaining this guide. Otherwise, if you’d like an affordable AA option for home or modest outdoor use, the ThruNite Archer is a great value.

The NITECORE EDC27 ($90) first launched at SHOT Show 2023. This light dazzled folks with a wonderful design and massive light output. If you can get your hands on one (it’s still selling out quickly with every batch produced), this light is the latest and greatest EDC flashlight on the market. I expect it to be popular for a long time.

I pick our best flashlights for several attributes. First, they need a bright white light capable of lighting a trail or workspace. My budget choice is 500 lumens, which is minimal to me. That’s enough to do a good job during a power outage or to light up the insides of closets at your home. If this is you, just get the Thrunite Archer and call it a day.

Where it really stands out is its magnetic base and side-throw lantern. This work light illuminates a larger area with soft, useful light at five brightness settings. In our testing, it was the perfect companion while checking for loose wires under the hood of a truck in the dark. And it’s capable of big tasks, too. It’ll kick out 375 lumens for 10 hours in work light mode or 500 lumens for 7 hours in standard mode.

The charging platform and magnetic charging cable keep this light from reaching the top of our list. We love the ability to recharge any electronic device. It’s cost-effective, better for the environment, and you’ll never have to hunt through your drawers for batteries. The Prowess can be charged with a USB-C cable, via its detachable base, and it can also directly connect to an MCC3 cable for super-fast charging.

To test durability, I dropped all flashlights from three feet and six feet onto concrete and put them in one foot of water for one hour. All of my recommended flashlights survived these tests.

While the Olight Warrior X Pro does give you excellent high-power performance, it’s weaker in the runtime category. That’s because its lowest power output is 300 lumens — more power than you usually need around a campsite. So for people looking for better runtime with lower outputs, there are better choices.

Some flashlights have side switches in place of, or in addition to, tail switches. A few flashlights also have physical switches that lock the flashlight in the “off” mode for safety and battery protection.

Thus, most of my choices here use rechargeable batteries. I hope to replace our budget choice with a rechargeable option soon, too.

We tested power banks from Nestout, Anker, BioLite, Goal Zero, and more, to help you find the best model for your budget and needs.

Brightest spotlight for hunting

While the ThruNite Archer ($30) lacks a few of the higher-end features of other lights on this list, it comes in at an excellent price of just $30. For that, you get a quality CREE XP-L V6 LED light source with a maximum power of 500 lumens. While that number may not look impressive, it’s way more than enough for most uses. Using two AA batteries, it has a runtime of up to 4 days on firefly mode and 11 hours on medium (75 lumens).

Regardless of the style of the buttons, they should be easy to learn and simple and reliable to use. We have tested and learned about the user interfaces in the flashlights in this guide. All of the lights here are effective and acceptably easy to use.

With an IP68 waterproof rating, it can withstand being underwater for 30 minutes at up to 6.5 feet. It’s also dustproof and shock-resistant. One feature I love is how easily you can manipulate between tactical (and strobe-enabling) functions.

NITECORE discontinued one of our previous favorites (the i4000R) but replaced it with an even better, more powerful torch. A strong contender for the best overall flashlight, the new NITECORE P20IX ($120) is one of the best flashlights on the market in terms of overall performance.

Bright Spotlight for backyard

Our primary flashlight testers are not just super into the outdoors; they’re also flashlight nerds. We really love the technology that goes into flashlights and headlamps. As the author of this article, I personally spend hours every month testing the newest flashlights to see if they can outperform our favorites listed here.

While some folks prefer AA battery lights, I disagree. You don’t replace the battery in your phone, do you? Or your earbuds? We’re all accustomed to recharging electronics in 2024. Let’s move past the archaic days of disposable batteries.

Most powerful handheld spotlight

Overall, the MT10 is one of the best flashlights you can buy, with most of the features an outdoor user will require. It’s reasonably priced as well, given its strong power and battery. I also appreciate its simple user interface.

So keep battery and charging style in mind when you buy a flashlight. It will make a difference when you’re packing for a trip as to how many cables you’ll need to bring, or if you’ll need to buy batteries continually through the life of the product.

The EDC33 has a bunch of other fabulous tech packed in the diminutive package. It has a great, physical lock to secure it in the off mode. Given the power of this light and the heat it creates, it’s very important. Fortunately, it’s easy to use.

The EDC33 packs incredible power, reaching a maximum of 4,000 lumens with a beam distance of almost five football fields. But even better, it has nice low and mid-output modes that are very useable at normal viewing distances of close proximity out to about 50 yards. And at that distance, this little powerhouse will burn and burn and burn, kicking out a very useful 300 lumens for nearly 7 hours straight.

Brightest spotlight for house

Another important consideration is if the flashlight uses its own rechargeable battery or if it runs on disposable batteries. Most people will get more value out of a flashlight that offers long runtimes and is easy to recharge.

Overall, I love this light. Some folks don’t like the single-button tail switch, but it works well for me. And the light will tail stand! If you want a tiny light that has a lot of power, this one is worth considering. It’s also a heck of a good price for so many features.

Under $30, you will usually not get a rechargeable battery. If you do, it’s likely lower quality and won’t have a very long lifespan. In this price range, expect mediocre performance for many jobs outside of basic home use. Our budget choice is the ThruNite Archer ($30). Though it runs on AA batteries and isn’t rechargeable, it’s a compact little light that packs a punch and is good to have around for emergencies.

Speaking of modes, the PD36R PRO ranges from a low-end 30 lumens to a searingly bright 2,800 lumens. At that 2,800-lumen turbo mode, you can easily see objects at 1,247 feet. That’s more than enough for most use cases for outdoor recreation. And impressively, the PD36R PRO can maintain that brightness for 3.5 hours.

Brightest spotlight on Amazon

Some flashlights recharge much faster than others. For example, the Fenix PD36R Pro uses USB-C charging at 2 amps and can recharge in less than two hours. Older micro-USB flashlights can take much longer to recharge.

However, it’s convenient to quickly change batteries and refresh your flashlight in the field. Both are valid options but consider how you’ll use the light (and if you mind constantly buying new batteries).

But more importantly, flashlights that include this type of high-end rechargeable battery do not have hidden costs. And those who will use a battery more than casually will find that the cost of batteries will very quickly add up to more than the cost of the flashlight.

Once on, depress that smaller switch to flip between modes. Or, you can press the smaller tail switch when the light is off to fire the strobe or momentary on modes. For the EDC user who may need to use the light for self-defense, this is a slick interface that should result in never hitting the wrong button for the needed use.

Conversely, if your eyes are adjusted to a sunny environment and you suddenly go into a dim tunnel, everything darker than the dark objects in the sunshine will suddenly appear black. You have probably experienced this yourself either entering or exiting a tunnel or dark room, and know that it takes several minutes until you can clearly see again in a new environment.

EIZO offers a device which can do all of the above. The RadiLight is a small light that attaches to the back of RadiForce monitors and gently illuminates the wall behind the monitor. This prevents any glare or reflections, and also illuminates the room to the ideal brightness. It also has an additional spot light on an adjustable arm which can be easily switched on and off with just the touch of a button, and moved to illuminate a specific area of your desk. It is made using non-reflective materials to ensure that light does not reflect onto the screen. The brightness of these two lights is also adjustable to ensure that the ultimate ambient lighting is achieved.

The Olight Prowess ($140) is a unique entree to our flashlight guide due to its charging system and the fact that it can be configured as a lantern. While we’re not crazy about the charging system, the lantern mode combined with its low light settings make it a very versatile light in emergencies.

Editor’s Note: I simplified our selections, removing several models from our primary guide during the August 2024 update to provide the easiest shopping experience. I’ve also included a price and value breakdown to help you what features you get when you spend a little more and how to pick the best flashlight for your budget.

Highpower LED Spotlight outdoor

The only ding against this compared with the more expensive Fenix is the build feels a little less robust (it’s IP54-rated for dust and water splashes and rain but is not fully waterproof). I also liked the color rendering a bit better on the Fenix. But the Ledlenser MT10  still puts up a great fight.

We put the Coast G32 ($25) in a head-to-head test against the Thrunite Archer, our overall budget choice, and the competition was neck and neck. In the end, the Thrunite defeated the Coast in the drop test. The G32 failed a brutal drop from 10 feet to concrete onto the lens, while the Thrunite survived.

A lumen is the basic unit of measurement for how bright a light is. The brighter the light, the more lumens it produces. The Merriam-Webster dictionary defines a lumen as “a unit of luminous flux equal to the light emitted in a unit solid angle by a uniform point source of one candle intensity.” For the layperson, a 1-lumen flashlight is barely enough to read a typical book at a normal reading distance from the face, or the amount of light of one birthday candle one foot away.

The Ledlenser MT10 also gives a great useable low light, running up to 144 hours at 10 lumens. It has a mid-power setting, but the brand doesn’t share specs on it. But at its middle setting, you get nice light for hiking and good runtime. I’ve only charged this flashlight twice in about a year of testing.

The highest-lumen flashlight currently on the market is the Imalent MS18, which claims a jaw-dropping 100,000 lumens. However, many huge claims like this are questionable. The brightest flashlight I have tested is the Fenix LR50R. It blasts out a verifiable 12,000 lumens and lights objects clearly up to 950 yards away!

The light packs a “Lumen Shield” mode, which it touts as a replacement for strobing self-defense. Call it what you will, but it’s a great, powerful floodlight. Finally, the light has a proximity sensor that automatically dials down the power when it’s too close for high output modes.

At around the $40 range, this light packs in a ton of performance that makes it fit for both the garage and the wilderness. It has a top output of 500 lumens — while not super powerful, that’s certainly sufficient for use on the trail and around the campsite. And it’s more than enough power when working under the hood of your truck.

The best way to control ambient light is with dim lights that are positioned behind the screen. As overhead lights – even dimmed ones – can cause glare and reflections it is recommended to position lights behind the monitor.

Better-quality lights also tend to have more efficient LEDs. Some even have “regulators” that electronically manage the power output, resulting in consistent lighting. To expand on that, first understand that most flashlights, even very good ones, lose a little output as they run and deplete the battery. Better flashlights use a regulator to manage this drop-off. Poor flashlights tend to lose power consistently over time, gradually becoming less and less useful as the battery slowly drains.

Beyond the specs, this is a perfect hand-size flashlight (5.74 inches long, 1.04 inches in diameter) with user-friendly functions. Turn it on and off at the large tail switch, press the smaller tail switch to adjust power, and check the LED near the USB-C charging port when turning the light on for a battery-level indication.

While these aren’t my absolute top choices, I have tested and liked all of the flashlights below. If you’re also a flashoholic or if these appeal to you more than my favorites, they’ll all serve you well. But since I realize most people just want to buy a good flashlight and move on with their lives, I’ve trimmed our primary selection list above down to the best of the best choices.

These flashlights also get significant field testing. Our team takes them on all kinds of adventures — hiking, mountaineering, backpacking, hunting, boating, and camping are all part of the mix. Most of our team’s tests occur in the mountains of Colorado and fields and forests of the Midwest.

Purely as a flashlight, the Prowess packs a powerful 5,000 lumens with a commendable beam distance of 245 m. Five levels of lighting allow you to dial in your preferred brightness-to-battery life ratio, with 10-hour runtime at 300 lumens. Not too shabby.

However many radiologists may find that this environment is too dark to comfortably read papers and make notes. For this reason a small light positioned below or beside the monitor is ideal for illuminating papers and notes on the desk.

The Fenix PD36R Pro ($120) is the latest evolution of our favorite overall flashlight on the market. A slightly upgraded model of the also-great PD36R, the PD36R Pro has one big improvement, and that is the dual tail switches. The system works like this: One larger tail switch turns the light on and off. The other toggles through the five brightness modes, or, if the light is off, activates the strobe function for self-defense. In the dark or with gloves, it’s still incredibly easy to manipulate the switches and get the desired output in seconds.

Most of the best flashlights, particularly smaller EDC flashlights, have a tail switch. The tail switch is usually a button that you press to turn the light on and off, and often also scrolls through brightness levels or other modes. Some of them have a momentary-on, which turns the light on through a partial press, which lets the light turn off when you release the switch. Others, like our favorite Fenix PD36R, have two tail switches to control different functions.

When choosing a flashlight, consider the following specs: size and weight, max power output (usually noted in lumens), minimum power output, runtime (especially in lower modes), durability, and waterproofness.

\But if you need your light more frequently in your vocation, a top power of 500 lumens is not sufficient. Tradesmen, law enforcement officers, guides, foresters, and countless other professionals and recreational users will simply want more power and functionality.

Charging preferences aside, the prowess is compact, plenty powerful enough for most applications, and the lantern function is super useful in camp or whenever the power goes out.

Let’s begin with the design. The NITECORE EDC27 is a flat flashlight with a pocket clip. That means it fits easily in your pocket. It will even fit in most knife pockets on pants, making it a dream to carry. To turn it on, press the large tail switch. Next to that switch is a smaller tail switch.

Controlling ambient lighting in reading rooms is vital to ensuring that radiologists are able to see scans and notice potential problems as optimally as possible. But why is it so important? Read on to learn the major reasons why ambient light is important, and how you can achieve the optimal reading room.

You heard that right — this flashlight does use AA batteries. That certainly brings down the price compared with high-end rechargeables and costs money to operate. Our team prefers rechargeable flashlights for several reasons I’ll get into below. But flashlights with disposable (or rechargeable) AA batteries are very easy to repower on backcountry trips — just bring a couple of extras.

As the above table reveals, flashlight prices vary widely. While a budget flashlight might seem like a good deal at first, there are good reasons for spending a little more for a truly high-quality flashlight. The battery, LED, and weatherproofing are generally superior in flashlights over about the $70 range. Here’s what you can expect:

This article has evolved significantly since it was first published back in 2018. At that time, it explained in depth why I love flashlights, and how they differ from headlamps. I still love flashlights for their directionality and ease of use in many situations. However, our team has done much more testing since this guide’s inception. I base our new recommendations on those results.

Eye fatigue can also be caused by glare and reflections on the screen, which causes the eyes to refocus each time vision is passed over the brightened area.
