But it won’t center the LED in any sized reflector. That butterfly one is specifically for use with XP- sized reflectors. With XM- sized reflectors it will only insulate, not center.
In fact, I believe that the M1 includes a special centering ring / spacer. If this ring focuses correctly you have two three options:
- Use the stock centering ring and “spin to center” the XP sized emitter. See this post #10 by will34 for an example of this technique.
- Use the stock centering ring and purchase an adapter from Hoop for $2. Hoop - FS : LED centering rings / positioning / insulating - made to your specs.
- Provide Hoop with the measurements from the stock part so that Hoop can make a whole new centering ring for the XP sized LEDs in an M1.
