Here is the link (yes it says skyeye, but it will say ultrafire on the light).

If you feel adventurous…there is now a 22mm custom Nangj style driver

This driver is 22mm in diameter. It is sized specifically for the new monolithic-head (no-pill) F13 flashlights such as the Ultrafire F13. The retaining ring threads on top of the 7135 cases. The 7135’s on top of the board have a setback such that the cases should clear the ledge inside the head, although the tabs may not. This should ensure good ground contact. I used ~20.5mm for the ledge.
On top of the board is space for the MCU, an SOD-123 package Zener diode, and a 0805 pa…
