If you’re comparing brands as well as models, our Fenix vs SureFire comparison discusses additional differences in design and features.
Design and Build Quality: Polymer vs Aluminum
When comparing the SureFire G2X Pro vs 6PX Pro, construction is one of the most important factors. Both are designed for demanding conditions, but they use different materials.
SureFire G2X Pro Design
The SureFire G2X Pro features a lightweight Nitrolon polymer body with a high-strength aluminum bezel. This combination helps reduce weight while maintaining durability.
The polymer body is corrosion-resistant and has a textured surface for a secure grip. It also feels less cold than bare aluminum when used outdoors in freezing temperatures.
Key design advantages:
- Lightweight polymer construction
- Textured surface for comfortable handling
- Corrosion-resistant body
- Durable anodized aluminum bezel
- Compact 5.2-inch design
At 4.4 ounces with batteries, the G2X Pro is comfortable to carry in a jacket pocket, backpack, or utility pouch.
SureFire 6PX Pro Design
The SureFire 6PX Pro uses a high-strength aerospace-grade aluminum body with a Mil-Spec hard-anodized finish.
This construction provides excellent resistance to scratches, abrasion, and corrosion. Its sculpted body also offers a secure grip, making it suitable for regular field use.
Key design advantages:
- Full aluminum construction
- Mil-Spec hard-anodized finish
- Strong resistance to everyday wear
- Sculpted body for better handling
- Compact design with a solid feel
The 6PX Pro weighs 5.2 ounces with batteries, making it approximately 0.8 ounces heavier than the G2X Pro.
Verdict: Choose the G2X Pro if lightweight comfort matters most. Choose the 6PX Pro if you prefer the feel and abrasion resistance of a full aluminum flashlight.
SureFire G2X Pro vs 6PX Pro: Brightness and Beam Performance
Both flashlights offer two brightness settings: 600 lumens on High and 15 lumens on Low.
The 600-lumen output provides strong illumination for outdoor navigation, property inspections, and emergency situations. The 15-lumen setting is useful for reading, working nearby, and conserving battery power.
Lumens, Candela, and Beam Distance
- High Output: 600 lumens on both models.
- Low Output: 15 lumens on both models.
- Maximum Beam Distance: 187 meters.
- Peak Beam Intensity: 8,700 candela.
- Beam Design: Optimized central illumination with useful surrounding light.
Both flashlights use efficient LED emitters and precision reflectors to create a balanced beam.
The 6PX Pro features a micro-textured reflector that produces a smooth beam with generous peripheral illumination. The G2X Pro also provides a useful combination of reach and surrounding visibility.
Because their rated beam distances and peak intensities are identical, neither model has a clear advantage in maximum throw.
For a better understanding of beam patterns, read our guide explaining flashlight flood and throw.
Battery Life and Runtime Comparison
Both the G2X Pro and 6PX Pro operate on two CR123A lithium primary batteries. SureFire includes two batteries with each new flashlight.
| Output Mode | G2X Pro Runtime | 6PX Pro Runtime |
|---|---|---|
| High (600 Lumens) | 1.5 hours | 1.5 hours |
| Low (15 Lumens) | 52 hours | 52 hours |
These are manufacturer-rated runtimes. Actual performance depends on battery condition, temperature, and usage.
For occasional use, the 52-hour Low setting is valuable. It provides enough illumination for many close-range tasks without using battery power as quickly as High mode.
Can You Use Rechargeable Batteries?
Neither flashlight includes built-in charging. Both are designed around two CR123A primary lithium batteries.
Do not substitute rechargeable RCR123A or 16340 lithium-ion cells unless SureFire specifically approves them for the exact model. Their higher voltage can damage electronics or create a safety risk.
Always replace both CR123A batteries together with fresh, matching cells. Avoid mixing brands, capacities, or old and new batteries.
For people who use a flashlight every day, a rechargeable model may be more economical over time. You can compare options in our rechargeable flashlight buying guide.

Real-World Uses: SureFire G2X Pro vs 6PX Pro
Although both flashlights offer nearly identical lighting performance, their materials and handling characteristics make each model more appealing for certain situations.
| Use Case | Recommended Model | Reason |
|---|---|---|
| Everyday Carry | G2X Pro | Lighter weight and comfortable grip |
| Camping and Hiking | G2X Pro | Less weight to carry on long trips |

Which Flashlight Is More Durable?
Both models are built for demanding conditions and feature rugged LED emitters, sealed construction, and impact-resistant components.
The main difference is how their materials respond to regular use.
The G2X Pro’s Nitrolon polymer body resists corrosion, reduces weight, and feels comfortable in cold conditions. The aluminum bezel provides additional protection around the flashlight head.
The 6PX Pro’s hard-anodized aluminum construction offers excellent resistance to abrasion and surface damage.
However, that doesn’t automatically mean the 6PX Pro will last longer. Actual durability depends on handling, storage, battery maintenance, and the type of impacts the flashlight experiences.
Verdict: The 6PX Pro has the advantage in all-metal construction, while the G2X Pro offers impressive durability with less weight.
Five Key Differences Between SureFire G2X Pro and 6PX Pro
1. Body Material
The G2X Pro uses a polymer body with an aluminum bezel. The 6PX Pro features a full aluminum body with a hard-anodized finish.
If you prefer lightweight materials, the G2X Pro is more appealing. If you prefer a metal flashlight, choose the 6PX Pro.
2. Weight and Portability
Both flashlights measure 5.2 inches long, but their weights differ.
- G2X Pro: 4.4 ounces with batteries.
- 6PX Pro: 5.2 ounces with batteries.
The difference is only 0.8 ounces, but it can matter if you carry your flashlight throughout the day.
3. Beam Performance
Both models deliver 600 lumens, 8,700 candela, and a maximum beam distance of 187 meters.
Despite their different reflector descriptions, their published performance specifications do not show a meaningful advantage in brightness or beam reach for either flashlight.
4. Grip and Handling
The G2X Pro has a textured polymer body that provides a comfortable grip. Its material is also less affected by cold temperatures when held with bare hands.
The 6PX Pro features a sculpted aluminum body that provides a solid, secure feel.
Neither design is universally better. Your preference will depend on how and where you use the flashlight.
5. Price and Value
The G2X Pro is generally the more affordable option. The 6PX Pro usually costs more because of its aluminum construction.
Since both offer the same rated lighting performance, the G2X Pro provides better value for buyers who don’t specifically need an all-metal body.
Are the SureFire G2X Pro and 6PX Pro Waterproof?
Yes. Both flashlights have an IPX7 water-resistance rating.
IPX7 indicates protection against temporary immersion under specified test conditions, generally up to one meter for 30 minutes.
This makes both models suitable for rain, splashes, and accidental brief immersion. However, neither should be treated as a diving flashlight.
To maintain water resistance, keep the battery compartment properly closed and inspect the seals for damage.
Which Flashlight Should You Buy in 2026?
For most everyday users, the SureFire G2X Pro offers the better overall value. It delivers the same rated brightness, runtime, and beam distance as the 6PX Pro in a lighter body.
However, the 6PX Pro is worth considering if you prefer the strength, appearance, and feel of aluminum construction.
Choose the SureFire G2X Pro If:
- You want a lightweight flashlight for everyday carry.
- You prefer a textured polymer grip.
- You need dependable lighting for camping and hiking.
- You want 600-lumen performance at a lower price.
- You prefer a flashlight that feels comfortable in cold weather.
Choose the SureFire 6PX Pro If:
- You prefer full aluminum construction.
- You need a durable flashlight for regular field work.
- You appreciate a hard-anodized exterior.
- You don’t mind carrying slightly more weight.
- You’re willing to pay more for the aluminum body.
Before buying, verify the exact model number and output sequence. SureFire also sells Tactical and Law Enforcement variants with different switch behavior, so don’t assume every G2X or 6PX flashlight works the same way.
