Olight ION Review: A Small EDC Accessory With A Big Throw Of Light



As the technology has advanced, the quality of EDC accessories has increased and the size has decreased. Here, we are particularly talking about flashlights.

Bulky flashlights have reduced greatly in size and are now available as keychain flashlights. Among notable brands, Olight ranks among top manufacturers of flashlights. And Olight ION is a prominent model among keychain flashlights, and we will throw ‘illuminating light’ on it in detail here.

Olight celebrated its one decade in the industry and shared the joy with its consumers. On its 10th anniversary, Olight released this special edition namely Olight ION.


One of the core factors, that users focus on when buying EDC accessories, is the size of the product and Olight ION comes up to users’ expectations precisely. With dimensions of 2.3 x 1.1 x 0.4 inches, it is an ideal keychain flashlight. Since it is compact, it is easy to keep in your pocket, purse, hold in your hand, or keep on your car’s dashboard.


It weighs in at just 6.2 ounces, which will not bother its user.


It is designed in a rectangular shape, made of titanium alloy frame, covered with gorilla glass on its front and back. There are 2 LED CREE XP-G3 lenses, which emit even more output when on.


It has a Micro-USB charging port, located on the side. Now most of the cars have USB port for charging, so if you are traveling in your car, it won’t be an issue when the flashlight runs out of charge. One and a half hour is enough to recharge it fully.

  • Red indicates charging mode.
  • Green indicates ‘completed’.


It has the limit of 320 lumens, which means that it can throw enough light to illuminate the area. The user can clearly view and recognize the object or person with such a powerful light. The sudden throw of light into the eyes can distract anyone for a few seconds. It means it can potentially work as tactical flashlight, but do not expect much in this regard.

Brightness Levels

Olight ION has 4 levels of brightness to choose from. Evidently, the highest level will consume battery faster. If you aren’t satisfied with preset levels, you have the option to customize the level. To activate the option, press and hold custom output.

Battery Life

It comes with a built-in LiPo battery. If you use it at its extreme limit of lumens, the battery will last for more or less 27 minutes.

If you keep the lumens’ range lower, battery life will keep increasing accordingly. It can last up to 90 hours if lit at 1 lumen.

It boils down to the fact that you can control battery life in accordance with your required use. Lumens can be adjusted with a dial on Olight ION.

Power Indicator

Another good thing with Olight ION is its power indicator which lets the user stay aware of the remaining charge, highlighted in different colors;

  • Green shows 75%
  • Yellow shows 15% to 75%
  • Red shows below 15%
