Surefire G2X Pro Flashlight Review


In early 2017 I found the Surefire G2X Pro while researching the most reliable and durable flashlights available. These two qualities are hard to find these days with all of the different features and materials being added to flashlights, but Surefire keeps it simple. Below you can read the results of my testing and my review.

Anatomy of the Surefire G2X

The Surefire G2X is right at the average size of flashlights I have reviewed on this site. It measures in at 5 inches long, and 7/8 inch around the body. These dimensions are at the high end for what I would consider a concealable flashlight, but did fit well in my pocket while I tested it over a few days. The weight with a 18650 battery installed is 4.7 ounces.

The Surefire G2X uses two 123A batteries to power the LED. This is the only flashlight to date that I have reviewed which uses two of these batteries, so it was refreshing to test a higher voltage flashlight (Two 123A batteries in series is 6v, an 18650 is only 3.7v). I measured the amperage draw on high mode to see just how long this battery will last, and found an average draw of .86 amps. The lower amperage draw is the result of the higher voltage provided by the batteries. 123A batteries usually carry about 1500 mAh in charge new, so you can expect about 1.5 hours of run time on high mode, with lower modes extending the battery life. Very respectable considering the light output.

I said above that the Surefire is one of the simplest flashlight I have reviewed and I wasn’t kidding. The operation of the G2X is as simple as High and Low mode which are activated using the tail cap button. One thing I did notice is how delicate the button is. Just a slight tap will turn the flashlight on or off.

The big selling point with the Surefire G2X is how reliable and durable it is. This starts at the internal design of the flashlight and extends outward. For example, most tactical models have two entry points to the internal components – the lens and tail cap. The G2X however has only one. The lens is permanently installed to prevent dirt and water from entering the flashlight. The tail cap is secured with a heavy duty seal. The body of the flashlight is made of aluminum alloy and covered in rubber. It is almost impossible to lose grip on this flashlight, even when wet, making it a great option for different climates and weather conditions.

Light Output Tests

One of most talked about feature of the Surefire G2x Pro is the light output, which makes sense considering it is a flashlight after all. I tested the ground coverage using a grid on my basement floor, and held the flashlight at waist height. On high mode, the G2x covered about 31 sqft (or 5′ wide by 8′ long). This is about the average of all flashlight I have reviewed and in line with similar flashlights like the Anker LC90.

The distance testing was extremely promising considering the high voltage provided by the batteries. On high mode, the Surefire’s effective distance was right around 80 yards, with a very large coverage area at that distance. That meant easy identification of objects in the distance outside of the central beam. You can see exactly what I am talking about in the image below which shows a grouping of trees at 40 yards away.

The Final Verdict

After all the dust settled, the Surefire G2X Pro was still standing and still clean! With the semi compact size, mid range battery life and extremely durable design, the Surefire G2X is a must for avid outdoorsman. I am rating the flashlight a 8 to 9 out of 10 stars.
