What is the best rechargeable flashlight for the money?

In this detailed review, we’ve selected the top 5 rechargeable flashlights with factors to look for, before deciding on the one you think is best for your needs.

What to consider while searching for the best rechargeable flashlight

You should look the brightness of light, durability, portability, beam distance, size, weight, etc features of a flashlight.

  • Material of the light

To begin with, it doesn’t matter if a flashlight is small, big, tactical or keychain type. If it’s not durable, then we can as well say you have spent badly on a product that will break or crush easily. A lumen light should be made from quality and strong materials that are impact resistant so that it can serve the user for a very long period of time. Pick an LED flashlight made from stainless steel or aluminum materials. These two materials are the best and will ensure that your rechargeable flashlight serves you for long.

  • Brightness level

The main reason why people buy a torch is because they want to light a dark place, hunt down something or use it as a form of alert. No matter the usage of the light, having a bright LED light is vital. The brightness level varies from one model to another and it’s important to pick one that comes with different lighting modes. The common lighting modes available include; low, high, medium, strobe and SOS modes. A rechargeable light with these 5 modes will enable the user have control of when to use which light, so that the battery can perform for a longer period.

  • Type of battery

Rechargeable flashlights are run by two types of batteries that can be categorized as removable and non-removable batteries. Removable batteries are those that can be used up to a certain level and will need to be replaced after sometime. Though, they are also charged. Non-removable batteries are those that are built in and cannot be replaced. The commonly utilized rechargeable batteries are lithium-ion batteries. Built in batteries are better than removable ones as they are environmentally friendly and tend to have a longer lifespan. The most popular batteries names are 18650, AA and AAA.

  • Beam distance

Depending on the purpose of the flashlight, one can opt to choose either a broad beam light or a spot beam light. Rechargeable lights are some of the best flashlight and the brightest on the market. This is because the rechargeable batteries they use run for long hours and are have a longer lifespan when contrasted to other batteries. If you are a hunter, fisherman or security personnel, you may need a flashlight with a spot beam so that you can view what is far or what you’re chasing. But for people who use led lights at home to search for a missing item or to view their backyard, a broad bean is what they need.

  • Size of the flashlight

Why are you buying the light in the first place? Is it for hunting, an edc item, for camping or hiking? Whatever use you have in mind, you should acquire a flashlight that is easy to use and operate while performing your respective activity. There are different sizes that can fit different purposes. For instance, if it’s for use at home, an edc or keychain light is well suited for the job. But if you need a powerful and brighter torch, then a medium sized or large flashlight will be ideal for the job. Hunters, fishermen and hikers need flashlights that are comfortable in their hands but at the same time offer bright light to see their target or destination.

  • Portability

A rechargeable flashlight should be easy and fun to carry. Since this is a must have item while out camping, driving or even hiking, it should be selected wisely. A high lumen light that helps you when you are in danger or facing the enemy should never be left behind. Thus, having a flashlight that you can carry always with you is very crucial for survival. Pick a light that is not heavy and compact in size so that it can easily fit in your pocket or bag. Some brands are very heavy and don’t encourage the user to carry them wherever they go. Ensure you select a stylish and lightweight best rechargeable flashlight so that you have it all the time.

  • Dust and water proof

There are some forces of nature that are difficult to escape, for instance, the weather. Since you never know when the weather of a place may change, it’s important to purchase an LED light that can withstand harsh environments no matter the situation. Opt for the best flashlight with water and dust proof features. When dust and water enter into a torch that isn’t resistant to them, its lifespan is greatly reduced and can lead to shut down. Also, acquiring an impact resistant flashlight makes the light last a little bit longer. Check out such features while looking for the best rechargeable flashlight.

  • Additional accessories

Flashlights are created from different brands. What may appeal to you may be bogus to another individual. Manufacturers add extra accessories to flashlight so that they can make them to be more versatile than just offering light. Also, some accessories make the lumen light to be more beneficial and convenient to the user in terms of use and performance. Things like pocket clip, chains and covers makes carrying and storing of the LED flashlights to be easy and secure. Pick a quality flashlight with the accessories that you need for convenience.

  • Brand

With numerous brands all claiming to create quality and excellent rechargeable flashlights, it’s important to identify the best from the rest. Go through reviews of previous buyers and as well select from well-known brands to avoid throwing away your cash. Brands such as streamlight, Thrunite, Nitecore, Surefire, Klarus and Solaray pro are wonderful in performance. You can choose from one of these or look out for other famous brands too.

  • Price

If you want the best, you will definitely have to spend more. But this doesn’t mean that the highly priced rechargeable lights are the best. If it’s cheap, don’t be surprised when it falls and crashes to pieces. The best thing to do is to research and find a lumen flashlight that has the features that you need at an affordable price. This will help a lot and you won’t be undecided about which light to buy and which one not to.

  • Warranty

Some flashlights are created in a poor way and won’t even last a year. So, it’s advisable to choose from a brand that offers at least one year warranty or replaces part.
Take your time and come up with the best rechargeable light for your needs but at the same time secure your investment with a brand that offers warranty.
