Description: The GLAREE E03 Keychain Flashlight is a sturdy product that will never fail you. It’s built to be durable enough to withstand being dropped into water, and the anti-abrasive finish means no scratches. No matter how hard you drop or bump it, it will look as great as the day you bought it.

On 1 AAA battery, this flashlight does run for quite a good while before needing to replace the battery. It even comes with a strobe mode, which is good for emergencies if you need someone to find you quickly enough. The battery doesn’t add much to the overall weight of the flashlight either, so you can keep this on your person or in the pocket of a backpack to use when you really need it.

This is also the brightest flashlight in this product review list, boasting 150 Lumens. Keep in mind, however, that this is the highest mode and can only be used for about 30 minutes, but that’s enough light to get you out of a dangerous situation quickly and effectively.

Things to Consider Before Purchasing

Before we can get started on showing you what’s out there in the market, we’re going to introduce you to some very important features. These are what can make or break your wallet. Despite keychain flashlights not being very expensive, you don’t want to waste your money buying flashlight after flashlight because they keep breaking or they end up being not what you’re looking for.

Instead, you should consider these important elements before purchasing so that you’re aware of exactly what you’re getting in the product you’re purchasing. Now that we’ve gone over the importance of why you should keep these in mind, it’s time to take a look at what they are.


Lumens are a unit of measurement as to how much light is being produced. A simpler way of putting it is how bright your light is. Keychain flashlights aren’t known for providing a lot of lumens, given their size, but they can be strong enough to help you get around in a blackout situation.

A flashlight with 20 Lumens is bright enough to read a book, and anything brighter than that is guaranteed to be useful in getting around your campsite after dark, or working on the underside of your car in a garage.

key flashlight

Keep in mind, however, that the brighter a flashlight is, the more they will drain the battery, so it would be a good idea to look for a flashlight with mid-range brightness or has brightness options for you to switch between.

Beam Distance

This is somewhat related to the brightness of your flashlight, as the brighter the light is, the farther the beam distance. However, this also relies on the kind of beam being used, as well as if there are any reflectors in the flashlight itself.

Depending on your activity, you may need a flashlight that has a decent beam distance. Longer beams are great for getting around in the outdoors and campsites, which can save you from tripping on tree roots and rocks in your path. Shorter beams are good for use in inside your home or car.


When it comes to keychain flashlights, they’re quite small which makes them a bit more vulnerable to breaking. They’re easier to drop and lose, but if you’re attached to a particular product, you don’t want to just give up on it. That’s why you may want to consider a flashlight that’s designed to deal with the elements, especially if you plan on taking it outdoors with you.

Look for flashlights that have impact-resistance as well as scratch-resistant finishes. These will save your flashlight from breaking on the first drop, and will also preserve its great look. Another consideration is water-resistance. You don’t want a little rain to make your flashlight stop working. Some of the products in this list can even withstand being submerged in water and continue working.


This is how many hours your flashlight can run for before the batteries are drained completely. This goes hand in hand with the Lumens of your flashlight, as brighter settings will use more power. Keep in mind that Lumens may decrease over time with constant use of a flashlight, so the runtime will decrease as well.

With that said, you should look for a flashlight with multiple settings so that the runtimes vary depending on your needs. You may need ultra-bright light for just a few minutes, or you may need a lower setting for a longer trip. Having both options provides you with more value for your dollar, as you’re allowed to use as much or as little of the battery as you need.


Without batteries, you have no power, but it’s important to consider the type of batteries your flashlight requires. A majority of keychain flashlights uses a single AAA battery, while other use several button/coin batteries. The latter is a little more expensive, but tend to produce a bit more light and have longer runtimes than the former.

One alternative is the rechargeable battery. This allows you to recharge the battery once it’s run out and use it over and over again instead of throwing it away. If you’re looking to be more green in your life, then this is an option you may definitely want to consider.

Wrap Up

You’ve arrived at the end of the article. With everything that’s been said, we’re confident that you’re on a better track to finding a keychain flashlight that’s suitable for your needs. It may take some time to find the right one, given all the information we’ve provided, but doing your research is better than going in blind and finding the wrong one.
