When looking for the best small flashlights one of the things you will want to look for is what style of switch they offer. Having one switch over the other doesn’t mean one is better than the other; switch type is all based on personal preference. For those looking for the best compact tactical flashlight tailcap switches are often preferred over side switches or a twisting head.
Some other things to look for are a sturdy pocket clip, a thin profile, overall size, durability, water resistant, light beam distance, shock resistant, and light output settings as these will all help you decide which light you want. Looking for keychain holes is also recommended as it ensures you always have the flashlight with you when needed.
When it comes to compact lights people often think that the best ones are not going to have much light output because of their small size. Many people mistakenly assume that if the light can fit into your pocket or be carried around on a key ring then there is no chance for it to be a bright light. However, that is not the case at all; some of the best compact flashlights have a maximum output over 1000 Lumens for a short amount of time.
So, what you want to look for in small flashlights is how much power they have to ensure they will be bright enough for what you intend to use them for. On the other hand we actually use firefly mode more than any other mode so make sure that you have output modes to cover all of your needs.
The style of batteries used should also be taken into consideration. Like many other flashlight styles compact lights use primary and rechargeable batteries, what kind you opt for will depend on what option fits your current lifestyle.
Sometimes we can’t believe how much LED flashlights have changed the flashlight market. The only reason we can get flashlight this bright and small is through the invention of the LED bulb, this would never be possible with an incandescent bulb.
