Lumintop FW3A 18500 Tube
These 18500 tubes are perfect for a noticeable EDC size reduction for the FWxx series. Coupled with the Vapcell K15 flat-top (15amp/1500mAh) cell and it's an excellent size/power ratio and my favorite combo. Great with the FW1A/Pro as well since that bezel in stock form is longer than the FW3 series... so a nice reduction there along with good aesthetics and hand-feel. Get these while you can... hope they make more of the copper and titanium ones!
