How to choose your rechargeable LED torch

If you want to choose your rechargeable LED flashlight properly, you should consider the following criteria:

#1 - Various uses

First of all, you choose a flashlight according to its use. Some people use rechargeable LED flashlights only to replace old-fashioned candles in case of power outage. Others use them during night hikes. They are also used by security personnel or handymen. The performance required is different depending on the use, but in any case, you want them to be operational at all times. You can choose between two beam widths: panoramic and spot.

#2 - Ergonomics, size and weight

Weight and size also matter. If you must walk with a lamp on your belt or in your hand, go for the lightweight model. Be aware that lights, rechargeable LED tactical lights are lightweight and very powerful. They offer both a very long life and a brightness that cannot be compared to incandescent lamps. No one wants to carry around a heavy flashlight in their bag. In practice, tactical flashlights tend to overheat when compact. For example, a 10 cm long flashlight with 1000 lumens of light output heats up faster than a 16 cm flashlight with the same light output value, regardless of the manufacturing material. If the lamp overheats a few minutes after use, you will have to switch to a lower wattage mode if the model has one. For everyday use, choose a type that is no more than 7 cm long. For outdoor enthusiasts, choose a flashlight with a light capacity approaching 1,000 lumens. Generally, flashlights 12 cm in length have this luminosity. For professionals, flashlights that are longer than 20 cm providing more than 1,500 lumens are the most efficient.

#3 - The power source

Power sources come in different types: batteries, cells, photovoltaic cells... Rechargeable batteries and cells have a good autonomy and are more practical in isolated areas. Some flashlights work with a mains power supply. Others can be recharged with a dynamo or from your car's cigarette lighter using a cable and a USB charger.

A special case: solar torches

Solar flashlights do not work in shadowy areas. Some models have separate solar panels that can be positioned or moved to capture the light. With outdoor solar torches, it is possible to create a usable outdoor space (garden, terrace...) regardless of weather conditions. The solar lamps are a design decoration for all outdoor events. They produce a flickering light effect.

#4 - The power


power is measured in lumens. The higher this value, the more powerful the flashlight is, and the more, it illuminates around it. Some models offer different power levels to adapt the brightness to your needs and save some battery life. Several manufacturers provide the value in lumens corresponding to the maximum power of the LED. But, you should keep in mind that practically and in most cases, you will lose up to 30% of power due to the energy loss caused by the protective lens of the LED and the reflector. For example if the LED has 1040 lumens max, this is not the value that is at the output of the lens.

#5 - Autonomy and regulation

You may have noticed that the moment the batteries or cells start to discharge, the light intensity tends to drop. For this reason, manufacturers have implemented in the new models of LED flashlights, especially tactical models, the regulation systems to regulate this intensity. The autonomy, meanwhile, determines the duration during which the user can operate his lamp. This criterion is not to be neglected, especially in case of an emergency situation. It should be noted that generally models with greater autonomy cost more.

#6 - Lighting range

The lighting range is one of the most important characteristics because it establishes how far the light beam can go to illuminate. And to see as much as possible, it's obviously better to have a longer range, unless your sole purpose is to use this lamp for repairs.

#7 - Certifications

The majority of high-end lamps are made with certain standards. The best known is IPX. It ensures that the lamp is rainproof and up to a certain level of immersion according to the number indicated, for example IPX-8 means that your lamp remains waterproof up to two meters under water. The lamp in question is not necessarily used for swimming at two meters under water. All flashlights designed for firefighters or employees working in explosive atmospheres are ATEX certified. They are explosion-proof. ATEX zones (ATmosphères EXplosives) are classified from 0 to 22.

How does a rechargeable LED flashlight work?

Equipped with LED technology, rechargeable LED flashlight is a very useful accessory for any outdoor night activities such as hiking, camping, but also for indoor uses. In general, it is designed for professional use and also has strong lighting capabilities. It is very practical because it can be worn on the forehead or wrist.

Indeed, it is thanks to this advanced technology that it provides a very powerful and long range lighting. As a reminder, LED stands for "light-emitting diode", which means semiconductor chip. In principle, the movement of electrons will emit light according to the principle of electroluminescence. The LED has a simple structure and is easily integrated into an electrical circuit.

Very simple to use, the rechargeable LED flashlight generally has the same operation as conventional bulb flashlights. In this sense, all the lamps need a power source to supply the light that the lamp will diffuse. Of course, what differentiates them is the power supply method. With traditional battery operated flashlights, the batteries need to be changed regularly.

The rechargeable LED flashlight, on the other hand, as its name suggests, is equipped with a battery or rechargeable batteries. Apart from that, in terms of power consumption, the rechargeable LED flashlight saves a lot of energy, as it consumes much less power. In addition, it guarantees long battery life for a long service life.

Battery or rechargeable torch?

Battery powered torch

Buying the battery-only flashlight is the right choice for the simple reason that with rechargeable batteries like NiMH, you will have access to maximum power. In addition, this type of battery is available in most stores, so you'll have no trouble finding one. However, if your flashlight runs on batteries only, you obviously have fewer charging options.

Rechargeable torch

With a rechargeable AAA torch, you'll definitely have a way to keep your batteries topped up. If you are in a remote location and the nearest store is hundreds of miles away, you can simply recharge your flashlight using its USB port. This type of device is considerably more expensive than simple AAA batteries.


If you're looking for a good AAA flashlight, look for one that has multiple recharging options, i.e., one that's battery-powered and rechargeable via USB. On the other hand, if you're looking for a good flashlight but don't have the money, a battery-powered flashlight is the perfect solution for you.


Don't confuse ultra power with long distance lighting

A lamp with a very high power of several thousand lumens will not necessarily light very far. This is not always correct. Of course, to light far, you need a certain power, but you also need a design adapted to the level of the lamp: the angle of lighting impacts on the range, the reflector has a role on the distance on which the luminous flux will diffuse.

The real power of a flashlight


take away 30% of the value indicated in lumens to have a rough idea of the real power. Also, beware of low-cost flashlights that claim to provide 1,000 or 2,000 lumens. Twelve-LED flashlights with 1,000 lumens do not necessarily provide 12,000 lumens, you need large batteries to achieve that value.

Choose between the different types of LED flashlight models available


night hiking enthusiasts and construction professionals, headlamps that keep your hands free are recommended. Also opt for this model if you need to grip during outdoor activities. For individuals who want to light a particular place or their way, choose a standard lamp. It is light, handy and suitable for mobile use. You can quickly neutralize your enemies both at home and on the street with the tactical LED flashlight with a switch on the right. The safety it provides and its power are the main advantages of this kind of flashlight. Tactical flashlights usually have high brightness and strobe mode, easy operation. They have a compact design with a very good grip. Emphasis is also placed on the ruggedness of the material, the simplicity of its interface and its resistance to water and shock.


What is the best rechargeable LED flashlight?

The best rechargeable LED flashlight depends on your needs and budget. Read our buying guide for the best products available.

What are the two main types of flashlights that are water resistant?

There are two main types of lamps that are water resistant: waterproof flashlights that can be immersed in water according to the manufacturer's specifications on the duration and depth of immersion, and water resistant flashlights that can be used in the rain, but cannot be immersed in water. Both types of lamps have a certain degree of waterproofing that allows them to be in contact with water.

Is there any way to prevent the battery life from being shortened?

It is advisable to always charge your new battery overnight before using it for the first time. This is called initialization and will ensure that you get the optimum capacity of the battery. Only charge the battery when it is about to be completely discharged. Avoid letting your battery discharge completely.

How to best maintain your flashlight?

You need your flashlight in almost every emergency situation. In order to do this, it must be properly maintained so that it can function normally without malfunction or incident. To remove dirt, we recommend using an alcohol swab or other degreasing cleaner. Q-Tips, a toothbrush, or other bristle pliers are needed to clean flashlights with slots or grooves. A lubricating lotion can be used to easily screw or unscrew your equipment.
