Choosing the Best Keychain Flashlights
Profile – there are different styles of keychain flashlights, those that have round profiles tend to use 10180 batteries. Flat and slim ones use built-in batteries. Flat and slim flashlights are great since they look and work similar to a key fob and can be operated with a simple push of a button. Cylindrical flashlights are usually twist operated, and while they do work well and are very reliable, some prefer button operated ones.

Brightness – the brightness of common LED keychain flashlights ranges from 100-500 lumens. Anything in the low range is still great to as high performance keychain flashlights tend to run hotter and have lower run-times.
