The Best Addition to Your Key Ring Since Car Keys
Once you put the Olight I3E around your keychain, there's no going back. Using its high-performance Philips Luxeon TX LED, it outputs 90 lumens from 44 meters away to best support daily activities despite the sun's best interests. With a weight under an ounce and a length of less than your thumb, you may forget that power is even there! With reliable output and compact size, this EDC key light is perfect for walking around the neighborhood, shining light in dark corners, or searching for any lost possession.

Replaceable or Rechargeable
This EDC runs on just one AAA battery, for power that is incredibly simple to replace. The I3E is also compatible with Ni-MH AAA batteries, for rechargeable options that offer a higher runtime of 70 minutes. Keep a few AAA batteries on deck for constant light, so that in any pursuit you're not left in the dark.
