This is the "big one"! This light is the UF-1504's big brother, which offers superb regulated runtime with 2x26650 capacity and the ability to run a buck driver. With the right setup, this light focuses into a laserbeam-like pattern with TONS of downrange throw, with the ability to zoom back in for close use.
This flashlight has nice anodizing, and great overall construction. Runtime is great, with a tube that can fit protected 26650 cells. You can also use an 18650 with the included adapter.
The body of this flashlight is heavy duty, with a high-quality thick aluminum tube body and this host is "clean", with no external markings.
Just add a 16mm MCPCB and 17mm Driver. Centering ring is designed for XM-class LEDs, but can be adapted to XP LEDs or not used is you want to run something bigger than an XM-class LED. For a 3V LED (XP-L, XP-G2, Nichia 219, XM-L2, etc.) a buck driver is needed to step down the voltage to the LED. The 17mm MTN-MAXlp HP was designed to fit and work in this light, and it offers the most performance you can get out of a 17mm buck driver. For a 6V LED, you can use one of the zener modified 17mm drivers.
Custom Build Service ***CURRENTLY UNAVAILABLE***
For an added cost, I will build and test this light for you. Just check the box and also add your choice of 17mm driver and 16mm LED to your shopping cart. If you add more than one LED or driver please specify in the comments section of your order which you would like me to use in the light. This service may add 4-5 weeks to your total order shipment time.
