Design & Build Quality: Polymer vs Aluminum
When it comes to everyday carry flashlights, the material and construction play a vital role in long-term durability. This is where the Surefire G2X Pro VS 6PX Pro comparison starts to show key differences.
Surefire G2X Pro Design
The G2X Pro is designed with a lightweight Nitrolon polymer body combined with an anodized aluminum bezel. This makes it corrosion-resistant and light enough for everyday carry. The polymer build is textured, providing a better grip—especially in wet or slippery conditions.
✅ Ideal for EDC and casual use
✅ Lighter and more compact than its aluminum counterpart
Dimensions: 5.2 x 1.5 x 1.5 inches
Weight: 4.5 ounces
Surefire 6PX Pro Design
On the other hand, the 6PX Pro features a high-strength aerospace-grade aluminum body. It feels more solid and is built to withstand impact, scratches, and rough handling. If you’re looking for a more tactical flashlight that can handle demanding environments, the 6PX Pro is a solid pick.
✅ Excellent for tactical, professional, or field use
✅ More durable but slightly heavier
Dimensions: 10 x 1.5 x 4 inches
Weight: 7.2 ounces
If ruggedness is your top priority, the 6PX Pro wins. But if you prioritize a lighter carry, go with the G2X Pro.
Performance & Brightness Output
Both flashlights come with dual output levels—high and low—but there are a few notable differences in their brightness and beam design.
Lumens and Beam Distance
- Maximum Brightness: 600 lumens (both)
- Low Output: 15 lumens (G2X Pro); 15 lumens (6PX Pro)
- Beam Distance: 165 meters (both)
- Candela (peak beam intensity): 6,800 cd for 6PX Pro (not specified for G2X)
Both flashlights use virtually indestructible LED emitters, and their reflectors are designed to produce smooth, optimized beams.
💡 G2X Pro uses a precision reflector suited for wide, soft illumination.
💡 6PX Pro has a micro-textured reflector, ideal for more focused beams with better throw.

| Output Mode | Runtime (Both Models) |
|---|---|
| High (600 lumens) | 1.5–2 hours |
| Low (15 lumens) | Up to 52 hours |
If you’re planning long-duration outdoor activities or emergency preparedness, the extended runtime on low mode is a major benefit.
