What are Keychain Flashlights Good for?

a human holding Keychain Flashlights

A keychain flashlight is a handy and dandy tool that makes it a perfect addition to your key clasp. It doesn’t take up much space and is super compact and lightweight. 

It is always a good thing to carry an EDC light with you. There are many reasons why it is sensible for you to include a keychain flashlight in your everyday go-to items.

  • Being prepared for different situations and potential emergencies
  • For safety reasons to make you feel secure
  • To find things conveniently

Key Factors to Consider When Choosing the Best Keychain Flashlight

Flashlight Output

There are three main factors to consider when it comes to a flashlight’s output. They are the light output, beam distance, and beam intensity. These three factors together influence the performance of the flashlight beam.

Light output

The amount of light delivered by the flashlight is measured in lumens.

Higher the lumen count, the brighter the light supply.

Beam distance

This is the length traveled by the beam path of a flashlight. And is measured in meters. This factor is determined by the light source and the reflector type employed by a particular flashlight. Greater the distance, the longer the illumination pathway.

Beam intensity

The intensity of the light thrown is measured in candelas. The higher the candela count narrower the light beam; the lower the count wider the beam.

A reliable flashlight ideally has an output ranging from 30- 250 lumens. It is even better if it offers a range of different modes to light different situations and last long.

Flashlight batteries

Considering the battery type and battery life of a keychain flashlight is important for preparedness. You can choose between disposable and rechargeable options.

  • Disposable batteries- these include the standard aa battery and aaa battery types. Flashlights using this option are usually much smaller and cost less. The drawback of using this is the ongoing cost due to the short battery life that will need timely battery replacements.
  • Rechargeable batteries- mini flashlights using this option can simply be recharged to use. You can save on battery costs and reduce waste. These flashlights offer better performance due to their high capacity. The initial cost of these is higher.

Durability

It is essential to consider the build quality of a keychain flashlight to determine its overall performance. The waterproof rating and impact resistance are derived based on the housing material and quality.

Information on these factors can tell you a lot about how well a keychain flashlight is reliable in handling various situations and conditions.

Size and Weight

Obviously, the smaller the keychain flashlight, the easier it will fit into your key rings.

Choose a model that is small, compact, and, more importantly, equipped to conveniently meet your requirements.

Price

Price is important too. Some people may have a budget, and some may not. No matter which category you belong to, choose the best keychain flashlight for your investment. But make sure to factor in the above points in doing so. 

Checkout the best flashlights for your specific needs.
