Today the typical household will likely have a minimum of two vehicles, and three stall garages are becoming more common. The need for car batteries and car battery repair will likely continue to increase in the future.

Flashlight Review: Olight M20-X Warrior 500 Lumens

I bought the Olight M20-X after doing a lot of online research on the different torches powered by 18650 or CR123A batteries. I was looking for a light that was as compact as a 2 x AA battery model but more powerful.

I found that most of the premium flashlight producers offered very similar models in this category, so I chose what I considered to be the best combination of output, runtime and price.

Editor rating
+ 9/10 all-around amazing gear
+ Great build quality
+ Strong even beam
+ Excellent runtime
+ Relatively inexpensive
– 250m throw claimed by Olight

  • Diameter: 33.5 mm (1.31”)
  • Length: 140 mm (5.51”)
  • Weight: 120.5 grams (excluding batteries) = 4.25 oz

First Impressions

The Warrior came with some useful accessories such as a glow-in-the-dark tail cap and spare o-rings. I was very impressed by the holster supplied. It is not only very sturdy, but also offers side pockets to carry spare batteries. There is also a battery case to stop CR123A batteries from rattling inside the holster.

Of course, the torch itself was my main focus of attention. I liked the solid build quality, and, after removing the tactical ring and the steel clip, the M20-X felt great in my hand too. The torch is made out of aircraft grade aluminium.

The M20-X has a lock-out function to stop it switching on by accident. It also has a momentary activation feature and memorises the last light level used.

The Warrior claims to fulfill the MIL STD 810F standard, which, after reading Wikipedia, has left me more confused than enlightened. I guess I’ll just have to test it myself under adverse conditions.


According to the Olight the M20-X Warrior has the following output and runtimes:

  • 500 lumens for 1.5 hours
  • 100 lumens for 5 hours
  • 10 lumens for 85 hours
  • 500 lumens for 3 hours Strobe

These figures were very important for me. Although the torch is brighter with CR123A batteries, Olight M20-X claims that the runtime is longer (one hour longer) with a single 18650 rechargeable cell. I was prepared to trade the brightness for the runtime and had decided in advance that I would power it with a 18650 rechargeable.

For my test I just fitted the flashlight with a fully charged 2600mAh 18650 battery, switched it on max and watched how the light developed until the very end. Continue reading “Flashlight Review: Olight M20-X Warrior 500 Lumens”
