I think we can all admit that flashlights are pretty cool devices. Whether you need to power your way through a power outage or repair your car in the dark, nothing can help you quite like a handy little flashlight. But the great thing about flashlights is that they don’t necessarily need to run on standard batteries. As a matter of fact, you can get flashlights which run on solar power—which is not only good for your wallet, but also for the environment. How cool is that? Cool enough, indeed, that it merits an examination of how they work, which we’ll take a look at in the next section.

How Do Solar Flashlights work?
Like other solar-powered devices, solar flashlights work by gathering in energy from the sun, which they can do so via their photovoltaic (solar) cells. Although the bulb can vary, they have often LED lights. Solar-powered flashlights have batteries, but they don’t need to be replaced as often as is the case with normal flashlights. They are an ideal choice for emergency kits or bug out bags, and are exceptionally helpful for those who live in remote areas where solar power is one of the main energy sources. With such a flashlights, you can see easily see objects that are up to 50 meters in the distance; however, beams of light being emitted from the device can be seen from much farther distances. The light can generally last for five to seven hours, if not more.
Things To Consider When Buying Solar Flashlight
If you’re buying a solar flashlight, you need to find the model that’s right for you. In order to do so, there are several things you’ll absolutely need to take into account before you bring your flashlight to the cash register, or hit “send” on Amazon. If you don’t, then you risk wasting money on a flashlight which you’ll never use because you don’t like it. Therefore, be sure to watch out for the following considerations when it’s time to purchase a solar flashlight. They can help you make the best decision, by finding the model that’s perfect for your tastes.
How portable is it?
Naturally, all flashlights are portable, but some are more portable than others, in that they’re lighter or easier to carry. In this case, the specific dimensions of the flashlight will depend on how you need to use the light. If you only plan on using the flashlight occasionally, such as during emergency situations, then you’ll probably be okay with a model that’s heavier. If, on the other hand, you use the solar flashlight more often—like if you use it at work, for example—then you’ll want a model that’s more portable, in that it’s lighter and the shape is less unwieldy. Moreover, smaller solar flashlights can easily be stored in a bag, a small purse, or even on a keychain; you won’t be forced to store it in the trunk of your car.
How does the light come out?
Some flashlights will create brighter light, whereas others will generate a more subdued lighting scheme. Keep in mind that you won’t be able to see anything with a brightness level of more than 150 lumens, so you’ll want to avoid such models, as they will cause you to squint and not be able to see properly. Even in the case of 150 lumens, that’s still quite a lot of illumination and is not necessary for most uses of solar flashlights. You can settle for less, such as 75 lumens, if (for example) you keep it on your person when you’re out walking your dog. 100 to 150 lumens is ideal for camping or hiking, however.
Controlling the light
However, one thing to keep in mind—aside from the brightness of the light—is how you can control the light. This is often done with a switch that you can use to turn it on or off. Depending on the model, you might be able to push this button with one hand, even if the flashlight model itself requires two-handed usage. You can also get models with simple switches that can be easily flipped on or off. On the other hand, some models will have more sophisticated controls. Thus, some models will allow you to change the mode from floodlight to spotlight, and so forth.
Will it last for a long time?
Many flashlights won’t work for more than a few months, and this consideration also applies to solar-powered flashlights. Thus, carefully examine the reviews of any flashlight you’re interested in before you make the purchase, to make sure that this problem doesn’t come up. After all, you’d ideally like your flashlight to last years and years (and not a few months).
