In-depth Review Of Rechargeable Flashlight
Due to its compact design this hand-held portable device comes in handy when you want to illuminate an area while still using your hands.
Technology has greatly evolved over time and now we have rechargeable flashlight that guarantee you light wherever you are whenever you need it. This brightest flashlight is not only last longer, but also produces more output giving you better illumination.
What is a Rechargeable Flashlight?
And it is one that combines a normal torch with a battery in one single unit.
This way the flashlight remains small but still has a higher output compared to a non-rechargeable flashlight. As a hand-held device, such as Cree Flashlight is a good lighting option as you only need to manage the torch and its charger. You do not need to worry much about carrying around batteries.
A rechargeable led flashlight can be charged directly from your main electrical power source or for some which come with a solar panel, can be charged using natural sunlight. Usually, a flashlight illuminates light through a small incandescent light bulb or light-emitting diode (LED).

Features of a Rechargeable Flashlight
A normal rechargeable flashlight will have a light bulb attached to a reflector, a transparent cover to protect the light bulb, a battery, and a switch. All these parts are then protected by a case. In our flashlight reviews, some of them have batteries that require to be removed from the flashlight and charged using an external charger. The advantage of such a flashlight is that you can have two pairs of batteries and always replace the drained battery with the fully charged pair. You, therefore, don’t need to stay in darkness as you charge the drained battery.
Then there are best flashlight that are internally rechargeable, you do not need to remove the batteries to charge them, simply plug the flashlight in a power source and it will start charging. This means you can’t use the flashlight until it has enough charge.
Some rechargeable flashlights come with a voltage regulator that allows you to adjust the light to different levels in order to save power and to also ensure that illumination remains consistent even as the batteries begin to drain. Others are designed to automatically shine brightly at the beginning of usage and keep getting dimmer as the batteries continue to drain.
Rechargeable flashlights get their light from a light bulb. The light bulb can be either incandescent, light-emitting diodes LED, High-Intensity Discharge (HID) or fluorescent. Each type of light source has its own advantages and disadvantages as follows:
The incandescent light bulb is the most common of all the bulbs. This type of bulb is used practically for every type of lighting. It is a basic light that comes in different types of illumination from bright to dim. Incandescent light bulbs consist of a glass bulb and a tungsten filament. The incandescent bulb is filled either with argon, krypton, xenon or halogen. Each of these fillers will determine how brightly the bulb shines. The halogen incandescent bulb is much brighter than the others while xenon is the dimmest. Halogen incandescent light bulbs are more efficient and they last longer than the other fillers.
The prices of an incandescent light bulb depend on the brightness of the bulb. Incandescent light bulbs are not that bright, even for the brightest type, and they are mainly more usable for casual around the house use. You know when you want to look behind a dark corner? Or when you want to run outside and pick your shoes in the darkness? Yes, such small stuff will be good enough for an incandescent flashlight. When buying an incandescent light bulb you really don’t have to go to an expensive one as they all work the same. You are better off saving yourself some money by getting the cheap one, it will work just as fine.
The incandescent light bulb for a rechargeable flashlight is replaceable and unfortunately it lasts only for a few hours. The light output of an incandescent light bulb depends on the type of lamp it is used in. For instance, a small keychain lamp will produce one or two lumens while a two-D-cell flashlight using a miniature lamp will produce between 15 to 20 lumens.
Fluorescent light bulbs are not so common with flashlights are they are bulky and quite inconvenient. Remember, a good flashlight should be easy to carry around and not heavy to bog you down. Fluorescent flashlights are usually used as emergency lights and not for every day, carry around use.
- High-Intensity Discharge (HID)
High-Intensity Discharge (HID) light bulb is not so common in flashlights, but it is available none the less. A HID gas light bulb has a mixture of metal halide salts and argon as a filler. The upside of HID light bulbs is that they produce more light than an incandescent flashlight. HID light bulbs also last longer and are more shock resistant compared to incandescent light bulbs. The downside is that they are relatively more expensive due to their complexity in operating them. A HID flashlight will normally have 35 watts light bulb and will produce more than 3000 lumens.
Most rechargeable flashlights these days use white-light-emitting diodes (LED)s instead of incandescent bulbs. LED light bulbs have seen an increased growth in brightest flashlight that are more sophisticated and can be used for more complex needs other than the normal every day around the house lighting.
LEDs are much preferred because they take only a fraction of the amount of power, they are lighter, run longer than all the other bulbs, and they do not need constant replacing as they never burn. LED bulbs are also shock resistant and less fragile. Rechargeable LED flashlight makes every aspect of a flashlight even better.
An LED flashlight will have a longer battery life compared to other flashlights and will also produce significantly more light than other flashlights. A typical LED flashlight produces about 100 lumens per watt, compared to 8-10 lumens per watt of small incandescent bulbs, making LED flashlights more efficient.
When it comes to colored light, LEDs produce more efficient color compared to other light bulbs. With LEDs you can select the different white and colored lights that you want and you can even mix them up if you want and use them for different purposes. Normally colored LED flashlights are used for signaling, special inspection tasks, or to track the blood trail of wounded game animals. Infrared LEDs, on the other hand, can be used for night vision systems.
LED light bulbs are more expensive than the other light sources because they have a different spectra of light compared to the other sources, and are also more efficient.
DIY Build A Rechargeable Flashlight!
Flashlights get power from different sources the most common ones being:
The most common power source for rechargeable flashlights is the secondary rechargeable lead acid batteries, NiMH, NiCd batteries and lithium ion batteries. Batteries can be recharged in several ways such as removing them and charging them using a separate external charger, plugging in the flashlight into an electrical power source without removing the batteries or for solar powered flashlights, use energy from a solar cell to charge the battery.
- Mechanical power
The most common mechanically powered flashlight is one that has a winding crank and spring connected to a dynamo that is used to charge a capacitor or a battery. Some mechanically powered flashlights will only work while the dynamo is moving. Others generate electricity using electromagnetic induction. A mechanically powered flashlight does not need replacement of batteries, or recharging from an electrical source as the flashlight is powered by electricity that is generated by the muscle power of the user by winding a crank, or shaking the flashlight itself.
The other source of power for a flashlight is the capacitor. There are indeed models of rechargeable flashlights that use a supercapacitor to store energy. A supercapacitor is a high-capacity electrochemical capacitor that bridges the gap between electrolytic capacitors and rechargeable batteries. The advantage of this power source is that it is recharges more rapidly than a battery and it does not lose capacitor no matter how many times it is recharged. Its running time is however, limited by, the relative bulk of capacitors compared to batteries. To charge a capacitor shake the flashlight causing it to supply current to a light source.
Who Benefits From A Rechargeable Flashlight?
Flashlights as already noted are very handy and can be used in several ways and almost everyone needs a flashlight. But in what ways do different people use rechargeable flashlights?
- Security Personnel – Security personnel probably need flashlights more than anyone else. Security guards working at night will need portable light that they can use for illumination as they move around. Having a charged flashlight is very important for every security personnel working at night or in dark places such as tunnels.
- Travelers – When you are travelling at night you will find it quite important to have a flashlight. Even when you are travelling during the day and you are probably going camping you don’t want to walk around with a generator to provide you with illumination at night, a rechargeable flashlight is your safest and convenient bet for this.
- Hunters – People who hunt as a hobby normally do so either early in the morning before dawn or at dusk. Both these times are dark and they therefore need a portable source of light that is easy to carry as they operate their hunting gear. Rechargeable LED flashlights especially colored LED ones are handy in illuminating a wounded animal’s blood track. How else are you going to find your catch if you can’t trace it?
- Individuals – Most individuals use rechargeable flashlights for casual use around the house everyday activities such as to find something in dark corners without necessarily having to light up the whole place. Individuals can also carry flashlights in their glove compartment, purse, pocket, or hang on a key ring for when you want light in dark places in or outside your house. Such a light needs not be bulky, making a flashlight the perfect choice.
Top 5 Tips to Choose the Best Flashlight
There are different types of rechargeable flashlights in the market and you therefore need to consider a few important things before you settle on one to avoid wasting your money and to ensure that you get the best out of your chosen flashlight.
- Power Output and Brightness
When buying a flashlight consider its power output and brightness. As discussed above, different light sources produce different power output and shine differently. You do not need to go for a very bright light if you are not going to use the flashlight for something that needs a bright illumination, an incandescent flashlight will be okay. However, if you are using it for more sophisticated needs such as for security or hunting purposes a bright light with a high power output will be needed. For such purposes it is good to have a flashlight that last the longest possible without the power dimming out.
If you are going to buy a flashlight whose power source is a battery then you have to be sure that you go for the right type of batteries. Depending on what you intend to use the flashlight for, you can choose between removable batteries or inbuilt batteries. A removable battery gives you the flexibility of having two pairs which you can interchange whenever one run out of charge. Removable batteries are normally cheaper than inbuilt batteries. On the other hand buying a flashlight with inbuilt batteries means that you don’t have to deal with so many movable parts. Flashlights with inbuilt batteries are also normally smaller than those with removable batteries. So again depending on how you want to use your flashlight you can choose between the two battery choices.
A good flashlight needs to work all the time otherwise it is useless and there is no need for you to carry it around. When buying a flashlight you have to consider its efficiency and durability. A good flashlight should be made from durable material such as aluminum, titanium, or some very special plastics. It should also have a seal that protects its insides from dust, dirt, and water. Finally the flashlight should be shock proof. A good shock proof flashlight is one that uses LED bulbs.
