Description
SureFire built the G2X Pro for people who need a light that just works, whether that means clearing a dark garage, walking the property at night, or riding along in a gear bag until the moment you need it. It runs a high-efficiency LED that produces two output levels: a punchy 600-lumen high that throws light out to roughly 187 meters, and a gentle 15-lumen low that stretches battery life for reading, checking IDs, or handling close tasks without blinding yourself. That range of usefulness is what makes it the most versatile light in the G2X family.
What Sets the G2X Pro Apart
The magic is in the tailcap. A press gives you momentary-on low, a click locks it into constant-on low, and returning to off then pressing or clicking again jumps you to full 600-lumen high. It takes about five minutes to get the sequence into muscle memory, and after that it feels natural in the dark. Behind the lens, a precision micro-textured reflector shapes a smooth beam with a bright center and a wide, useful spill so you keep your situational awareness instead of staring down a narrow tunnel of light.
Built From the Nitrolon Body Out
This is where the G2X Pro earns its everyday carry reputation. The body is SureFire's tough Nitrolon polymer, which shrugs off scratches, impacts, and corrosion while staying light in the hand. One underrated perk of the polymer is that it holds a neutral temperature in cold or wet weather, so you are not gripping a freezing metal tube with bare fingers. The bezel is hard-anodized aluminum, the lens is impact-resistant polycarbonate, and the whole thing is O-ring and gasket sealed to keep rain and snow out.
Power comes from two 123A lithium batteries, which are included and carry a long shelf life, so this light is genuinely ready to go the day it arrives. It is a natural fit for hunters, first responders, and anyone who wants a dependable light that fits a pocket, glovebox, or pack. The 1-inch body also drops into most standard weapon mounts if you want to run it that way.

Frequently Asked Questions
How do you switch between low and high on the G2X Pro?
The G2X Pro uses a single press/click tailcap. A press gives you momentary-on low and a full click locks in constant-on low, then you return to off and press or click again within a couple seconds to jump to the 600-lumen high. It always starts on low, which is handy for preserving night vision before you commit to full power.
What batteries does the SureFire G2X Pro use and are they included?
It runs on two 123A lithium batteries, and SureFire includes a set in the box with a long shelf life so the light is ready to use right away. It is also compatible with SureFire rechargeable 123A cells if you want to reload it over time. The lithium chemistry is a big reason this light performs well in cold weather.
Can the G2X Pro be used as a weapon light?
It can. The 1-inch body diameter fits most standard weapon mounts and rings, and the press/click tailcap works well with pressure or grip-style setups. Plenty of owners run it handheld for everyday carry and mount it when needed, which is part of why it is such a flexible pick.
Is the G2X Pro waterproof?
It is O-ring and gasket sealed, so it is built to handle rain, snow, and wet conditions without a problem. The Nitrolon polymer body also resists corrosion and holds a neutral temperature in cold weather, which makes it comfortable to grip bare-handed. It is a genuine all-weather tool rather than a fair-weather flashlight.
