Host is the New SS version of Ultrafire C3, it's got the new smaller Cree EZ900 Q5 in it.
The light has been cut & converted to CR2. Running 14250 Direct Drive.
From the Ultrafire Stainless "family photo". the host is the one on the left:
The Swap of XPG R5 is easy, when perfectly focused, the R5 on 10mm board is 1.5 mm away from
bottom of the reflector, which allow Room for the wires & solder pad (They are so close to the die & partially
stays in side of XRE reflector opening).
The C3 has a great reflector, in the stock light, it focused the EZ900 Q5 into a very small & perfectly even spot. Unfortunately, the XPG on the C3 reflector gave a donut effect, with beam center be slightly dimer than the edge of the hot spot. As a white wall hunter, I was not happy with the beam at all!
Another reflector I tried is IMS 17mm, it still gave donut effect, although less pronounced than the C3 reflector.
The, I stippled the IMS, hopping to smooth out the beam.
It's better but there still has a bit of donut left, This is very frustrating!
Keep trying, I swapped in an 17mm Smooth reflector from a cheap 1W nichia flashlight,
Finally! the donut is gone! There still some beam imperfections, so I stippled the smooth reflector to a light OP.
Final Result:
The XPG R5 in C3 CR2: I used a 1.5 mm IC board to precisely gap the LED from reflector.
Huge hot spot & Crazy amount of light from the 14250 DD XPG R5:
Last, the direct side by side of before & After.

Right: EZ900 Q5 Ultra Fire C3 stock light on high( it has 5 modes) with 1.9V E2 Lithium battery

Final Result:
- Huge hot spot
- Huge amount of light
- Greatly Increased flood
- Reduced throw
