Or you can get one from Kaidomain, like this one:
http://kaidomain.com/Flashlight-DIY-and-Tools/led-drop-in/KDLITKER-P6-LED-Drop-in/KDLITKER-P6-TRI-Triple-Luminus-SST-20-1000-Lumens-3V-9V-P60-Drop-in
- Uses a buck driver, so supports voltages from a 3V-9V input, so you can use 2xCR123As with a compatible light for emergencies, or 2x18650 with a long P60 light for completely regulated runtime.
- Triple 95CRI 4000k SST-20, so excellent color rendition and tint.
- A max current of 2,8A with a buck driver and triple LEDs means it is quit efficient, and can sustain it nicely, even with CR123As.
- It has a nice Very Low-Low-Medium-High user interface. You can ask Kaidomain to customize the firmware so you can get even lower lows, and more modes in between. Just ask, and they will do it for you.
