Solar Power Flashlight

solar flashlight

If you’ve come here wanting information on how to choose the best solar flashlight on the market to suit your needs, then you’ve absolutely arrived in the right place.

At one time, it would have been unthinkable to imagine implementing a solar cell array powerful enough to sustain not only a functional but also a highly usable handheld light for home or work use.

Luckily, that’s all now changed. We’re now going to tell you everything you need to know about what these products are, how they work, and how to choose one that’ll best serve your requirements.

What Is a Solar Flashlight?

The fundamental difference at play between this type of flashlight and others is the manner in which the light powers itself. Normally, this would be via disposable or rechargeable batteries. But in this instance, the unit relies almost exclusively on the power of the sun, and specifically solar cells.

These cells rely on photon rays being sent down to earth from the sun’s core, which they then readily absorb, convert, and distribute as usable energy throughout a connected power circuit.

In the case of a solar flashlight, the circuit is used to power an LED light, surrounded by permanent housing that we can hold and carry with us.

The reasons why you would select a solar variant of this traditional technology are numerous, but at large, it’s because you’re going to save money due to not having to replace batteries as frequently as you normally would and the convenience associated with this.

How Does a Solar Flashlight Work?

You already know that a voltaic cell structure is required for photon ray intake if your flashlight is going to be classed as “solar powered.” But depending on the model you choose, precisely how it functions is going to differ fairly dramatically.

Everything from standard to USB to hybrid and crank-powered models are available to cater for a variety of different needs for pretty much any user type.

In conjunction with a voltaic cell array, these variants also feature added hand cranks or USB ports, or a combination of battery ports and voltaic cells to ensure that you can both charge and keep your light charged regardless of your circumstances. Some include all of them.

If daylight hours are restricted in your area or you need to make use of your light for an extended period of time and you’re worried that solar power alone might not fully cover your needs, this is where these alternative varieties can be called upon for maximum peace of mind.

How to Choose the Right Solar Flashlight

In this section, we’re going to tell you exactly what features and design specifications to look out for when searching for a solar power flashlight.

After reading through the below points, you’ll find the relevant flashlight features that resonate with your individual circumstances.

Beam distance and type

Traditional focus beams are the most common variety and are often used for residential purposes or even in some commercial settings. This is the standard type of beam that you’d expect to see coming out of a handheld light and it appears in a narrow arc.

Flood light and strobe variants are also available. Combined with the beam type, you’ll need to know how much distance it can cover. The further the beam can project, the further you can see.

Resistance against impact and water

Consider where you’re going to be using your light and what for. If it isn’t durable, then it might not withstand the environment you’re placing it in. That could be disastrous if you’re relying on it for the safety of yourself or others.

The same can be said for water resistance capacity. If you know that you’ll be taking it through watery terrain, then a lack of effective water resistance could create an entire wealth of issues for you and others.

Light output

Solar-based lights can hold their own against traditional battery-based variants, but some are much dimmer. Make sure that you check the lumen count on your chosen model because it might not be high enough to cater for your needs.

Lumens are the means by which we measure light output. Solar flashes usually rate anywhere from 60 to 300 lumens. Please bear in mind that this is the crucial number you need to pay attention to when it comes to output as opposed to the number of LEDs a light contains.

Run time

Next to output, or on par with it, this is the other vital area to pay attention to, as you’ll be relying on run time along with output to cater for your specific portable lighting needs.

Home use isn’t likely to require an elaborate degree of run time, but if your light is going to be involved in any form of security or defense, you’ve got to make sure that it can last for the length of your active work time. An average run time would be 15 hours for solar tech-based handheld lights, but this number can vary widely.

Recharge time

This is an important factor to consider if you’ve got to make frequent use of your flashlight with small turnaround times.

On average, it takes a light of this variety six hours to charge. But as with any of these elements, that can massively vary depending on the quality of the product. If your job relies on flashlight use, you need to be able to pick it up as frequently as possible and possibly at short notice.

Additional features

Though added bonuses shouldn’t be your primary concern versus most of the above features and specifications, they can still make an enormous difference in the way you practically approach the circumstances you’ll be using your flashlight in.

Everything from seatbelt cutters to AM/FM radios, utility knives, and compasses may be integrated into the housing of a solar flashlight.


Here are some of the most renowned manufacturers of solar-based handheld light systems: NPET, Gearlight, NoCry, Kizen, Meco, PrimalCamp, ThorFire, Vont. Any product purchased from one of these brands is likely to be of high quality.
