Why we picked the Lumintop Mini LED Flashlight:

Small but mighty, the Lumitop Mini Flashlight suits campers, anglers, survivalists, and other outdoor enthusiasts. Ideal for boating, it withstands immersions to 6.6 feet for up to 30 minutes, and – obviously – it can also be used in heavy rain and humid environments.

Besides utmost water resistance, we also like its strength. This flashlight withstands shocks and works even in extreme temperatures. It’s small enough to fit in a pocket, and comes with a convenient lanyard. Suitable for everything, from walking the dog to camping to using in emergency conditions, the Lumitop Mini is undeniably one of the best waterproof flashlights on the market.

Its performance isn’t mind-blowing, but with its 55 lumens, it still features a beam distance of 31 meters. That’s more than enough to see what’s in front of you while you’re exploring the wilderness after dusk. Powered by standard AA batteries, it could be your trustworthy camping companion if you don’t want to break the bank.

4.5/5

Technical Specs:

Why we picked the ThruNite TN42 Waterproof Flashlight:

The ThruNite TN42 might be costly, but it’s undeniably the ultimate waterproof flashlight. Outstanding lumen output and beam distance, as well as IPX8 water resistance make it a winner. Our favorite feature is the oversized design that makes it easy to grip. Despite its weight, the flashlight is ergonomic, but not your best bet for backpacking. 

The flashlight runs on proprietary lithium-ion battery that can be replaced by four 18650 batteries if you don’t have a USB outlet nearby. Powerful and designed to last, it is a great choice for car camping, tailgating, and boating alike.

It has a slim, ergonomic design that makes it easy to carry – just keep in mind that it’s relatively heavy. We particularly like its recessed lens design that enhances resistance even if you drop it. The flashlight is powered by six AA batteries and outputs particularly bright light – ideal for tactical purposes as well as night hiking.

Waterproof Flashlight Buying Guide

We can never really tell the weather during outdoor activities. One minute it could be sunny another minute it could be raining cats and dogs. Outdoor gears need to always be ready for any sudden change in weather. Hence it is best for gears to be waterproof, even flashlights.

We listed here factors that need to be considered before purchasing your waterproof flashlight from the brightness, waterproofing, battery life, and other factors, you’ll find it here. It is uncommon to be shopping for a flashlight but if you are somebody who loves to travel or enjoy the outdoors, this best waterproof flashlight buying guide is for you. 

Waterproof Ability

This should be the number one consideration when looking for a waterproof flashlight. An object’s waterproof ability is gauged and measured via its IPX rating. IP stands for “Ingress Protection” and the X tells the user that there is no dust rating. On the lower end of the IPX rating system there is IPX-0 which means the housing is not water-resistant at all and any contact with water will result in damaging electronic components.

Waterproof flashlights IPX rating range from IPX4 to IPX8. Take a look below for a quick description of the different IPX rating for your reference:

  • IPX4 means the flashlight is protected against splashing from any angle. 
  • IPX5 means it is protected against low pressure water streams from any angle.
  • IPX6 means it is protected against high pressure water streams from any angle.
  • IPX7 protected against water immersion for about 30 minutes at a depth of up to 1 meter.
  • IPX8 protected against continual submersion in underwater conditions.

This means that the  Lumintop Mini LED Flashlight can be fully submerged underwater given that it has IPX8 rating. We also chose the  Lumintop Mini LED Flashlight as overall waterproof flashlight because it is not just waterproof but shockproof as well and can work amazingly under extreme temperature. 

For outdoor activities like camping or trail running, the IPX5 rating of the NICRON N7 Tactical Flashlight is still at a good level. It is still dependable outdoors to provide for your lighting needs even during sudden change in weather conditions. 

Lumens

 

As with any outdoor gear that provides light, lumens rating is one major consideration. The term “lumens” quantifies the amount of light being put out by a light source. Flashlights are equipped with around 300 lumens although some advanced ones go for up to 1200 lumens (these are generally used for special instances like rescue missions).

It is recommended to avoid anything that falls way below that range. Although it is important to note that the amount of light decreases as your power source decreases. Meaning if you are bound to change your batteries, the brightness of your flashlight will decrease significantly.

For heavy-duty outdoor activities or special instances we recommend our premium choice, ThruNite TN42 Waterproof Flashlight with its 2,000 lumen output rating. You are guaranteed a powerful light source despite being underwater given its IPX8 rating as well.

Floating Feature

 

Aside from being waterproof it is an additional feature if your waterproof flashlight can also float. This feature would come handy for you since it will allow you to recover your light source easily in the event that you lose your grip on it. The Dorcy 55 Floating Waterproof Flashlight has this feature that we recommend; it will not submerge fully when it falls in the water. Instead, it will float at the surface of the water. The Dorcy 55 Floating Waterproof Flashlight might not be the most powerful waterproof flashlight on the list, but it can provide basic light source with 55 lumen output at a beam distance of 35 meters.

Beam Distance

Beam distance refers to how far the light beam can travel. This value is often referred to as a flashlight throw or range in the product’s packaging. Beam distance is an equally important number. A headlamp with a 100m beam length will allow you to see 100m in front of you in good conditions, while a 600m beam length will allow you to see 600m away. Beam distance needs to be checked if you plan to use your waterproof flashlight in extreme conditions requiring larger distances.

This is where both the ThruNite TN42 Waterproof Flashlight and the Zohi Waterproof Rechargeable Flashlight excelled. The two have the largest beam distance on the list 1550 meters and 450 meters respectively. Both can be used in extreme conditions requiring both large beam distance and high lumen output with the ThruNIte at 2,000 lumens and the Zohi at 1,500 lumens, these two are powerful and heavy duty.

But generally a beam distance of a few hundred meters like the 171 meter beam distance of Streamlight ProPolymer Dualie Flashlight is acceptable for light camping needs.

There are a few exceptions with models that have low beam distance like the UST SplashFlash Waterproof Mini-Lantern, that has a short beam distance of just six meters. This type of waterproof flashlight caters more to personal use and for emergency circumstances hence the compact and lightweight design.

Average Battery Runtime

The type of battery in a flashlight is a key determinant of how long it can run, this is usually indicated in hours on the packaging. The two most common batteries used in any lighting gear are alkaline or lithium-ions. With lithium-ion being much preferred due to its longer lasting battery life.

It is worth noting that if you are constantly using your waterproof flashlights maximum settings for brightness, your battery charge might deplete pretty fast. In this case, it may be a good idea to consider investing in a rechargeable model. Like the LumiNRG Tactical Flashlight that comes with rechargeable batteries but also has a USB for alternative power source which you can use after you’ve used up its 10 hours battery runtime.

Though the battery runtime is determined by how you use your waterproof flashlight, we find the 65 hours battery life of the Rayovac Waterproof Tactical Flashlight pretty amazing. It is a good choice if you plan on going to outdoor dusty locations as it is also dustproof.
