Solar-Powered Flashlights

Today, with the rise of environmental concerns, a lot of people prefer environmentally friendly products. The good news is that you can purchase a solar-powered flashlight if you prefer products that are safe for the environment. This type of flashlight is convenient to use, and it is strong enough for various purposes.

A solar-powered flashlight is weaker compared to an LED and HID flashlight. Still, it is a cost-effective device that is comparable to an incandescent bulb flashlight, especially when properly charged. An advantage of this type of flashlight is that it can be charged by exposing its solar panel to the sun. As such, you can save some money because you don’t have to buy batteries from time to time. Unfortunately, most solar-powered flashlights have a short run time, so they can be unreliable during long power outages.

Shake Flashlights

Shake Flashlights

Shake flashlights were introduced by Michael Faraday om 1803. As its name implies, this type of flashlight will turn on by shaking the device. To explain further, it is powered by several magnets inside the flashlight. When you shake the device, it will cause a reaction, which will provide light.

To use a shake flashlight, you have to shake it for three seconds to three minutes. Typically, three seconds is enough to turn on the device; however, you may need to shake it a little longer if the capacitor is drained. Once the light begins to lose its power, you have to shake the flashlight again to keep the light charged.

Despite its cool features, the shake flashlight doesn’t produce a very bright light. Still, they will work when needed, plus they are not too expensive. So, if you want to save some money on batteries, this type of flashlight is a good option.

Styles of Flashlights

Utility Flashlight

Incandescent bulb flashlights are the most common utility flashlight. They are affordable, and they produce light that is enough for most purposes. However, most utility flashlights are not durable and will break easily when you accidentally drop them.

As such, tactical flashlights should produce very bright lights. Aside from that, they are also durable and can handle rugged treatment. Plus, they can also withstand various weather conditions.

How to Pick the Best Flashlight?

As presented, there are various types of flashlights. Because of this, you may have a hard time picking which flashlight is best for you. To help you find the right product, here are some features you need to consider when buying a flashlight.

Purpose

One of the most vital factors you need to consider when buying a flashlight is its purpose. For instance, if you’re going to use a flashlight around your house or when you’re going to walk your dog at night, a pocket-sized flashlight is recommended. For hunters, it is best to opt for a flashlight with a tight beam that will allow you to see far-away objects. Lastly, law enforcement officers can opt for flashlights with a high lumen. This feature will be useful for various purposes, such as search and rescue operations.

Light Output

In terms of flashlight output, there are two things you need to consider, which are beam intensity and brightness.

The brightness of a flashlight is measured in lumens, which tells you how much light is produced by the flashlight. Typically, flashlights with higher lumens will produce brighter light. However, opting for a flashlight with 2,000 lumens is not recommended. Ideally, 800 to 1,200 lumens is enough for most users. You’ll need a higher lumen if you want to light up far-away objects.

Bean intensity, on the other hand, is measured in candelas. A flashlight with higher candelas will produce a more focused beam, while those with lower candelas will have a less noticeable beam or center point.

Durability

Aside from the flashlight’s output, you also need to consider its construction. As you know, flashlights are made with various materials, including plastic, aluminum, and polycarbonate (PC).

Flashlights that are made with plastic are not only lightweight but easy to maintain as well. However, plastic is not as durable as metal, so it may break if you accidentally drop the flashlight. Most LED flashlights, on the other hand, are made with aluminum because it provides a strong shell while being lightweight. As for headlamps, they are typically made with PC materials because they are lightweight, but they are not as durable as aluminum.

Water Resistance

Aside from the material, you also need to consider the flashlight’s ability to withstand water. Remember, you’re going to use your flashlight outdoors where it can be soaked by water, especially during heavy rains. For this reason, it is best to opt for a water-resistant flashlight.

Typically, a flashlight with a waterproof rating of IPX4 can withstand rain. If the flashlight has a waterproof rating of IPX7, it means that it can be submerged in water to a depth of about one meter. The rating IPX8, on the other hand, means that the flashlight can be submerged in water to a depth of more than one meter.

Run Time

The run time of a flashlight will determine its usefulness. Typically, the run time of a standard flashlight will decrease by 10% after you use it for about 15 minutes. Of course, flashlights with strong batteries will have a longer run time; thus, you have to check the battery of the flashlight. Lastly, the size of the flashlight will also affect its run time.

Size and Weight

Another important feature you need to consider is the size and weight of the flashlight. As mentioned, larger flashlights will have more run time because they have bigger batteries. Additionally, they will also produce brighter lights. Even so, small flashlights are also powerful, and they are also lightweight. As such, you can easily carry them around.

Batteries

When buying a flashlight, you also need to consider the batteries. Most people prefer flashlights with a high-quality rechargeable battery because of their convenience. You can also opt for flashlights powered by non-rechargeable alkaline batteries, which can be handy when you’re on the go or during long power outages. Unfortunately, alkaline batteries are expensive and harmful to the environment.

If you don’t want to use batteries, you can also opt for a solar-powered flashlight, which you can recharge by exposing to the sun. Shake flashlights are also great because you only need to shake them to produce light.

Budget

As mentioned, the different types of flashlights have various prices. If you’re looking for a flashlight that you can use at home, you can opt for budget-friendly incandescent flashlights. But, if you have more money to spend, you can pick a better type, like an LED flashlight or USB charging flashlight. Aside from being brighter, these types of flashlights are more durable than incandescent flashlights. Of course, flashlights designed for special purposes are more expensive than their regular counterparts.

Final Thoughts

A flashlight is a handy device you can use for various purposes. As presented, there are different types of flashlights, and each type has its pros and cons. You have to understand these various types, so you can find the best flashlight. Additionally, there are several features you also need to consider. Features, such as light output and run time, will help you determine if the flashlight you’re going to pick is suitable for its intended purpose.
