P25GT Runtime, Multiplied by 2.5

Add the ET25GT and a 4500mAh 26650 cell to your P25GT and the light runs about 2.5 times longer than it does on a single 26350.

One Light, Two Lengths

Run the short configuration for pocket carry, then screw on the extension for long nights when charging is not an option.

Mil-Spec Aluminum, Matched Finish

High-strength aerospace alloy, hard anodized to the same specification as the P25GT, with threads that seat cleanly every time.

17 Grams, 37.5mm Long

The extension measures 37.5 mm by 33 mm and weighs just 17 grams, so it adds runtime without adding bulk to your kit.
