Should this setup blow a brand new XM-L2 U4?

Retaining ring is metal. You shorted across the + to - pads on the MCPCB. You could have fried LED, driver, or both.

I made that mistake on my first 1405 build.

Upon closer inspection you are correct. However, I don’t believe this shorted it out. I had pressed my solder points with a small flathead to keep them as low as possible. Plus with the reflector spacer and the way the ring is shaped I think there was room to spare.

You might want to include some kapton tape in your next order for insulating solder pads from the reflector. Mostly a problem in smaller hosts and p60 builds using thicker wire.

I probably will pick up some of that tape, but I ended up soldering an XP-G2 right to the pill, so no retaining ring needed. Chugging along fine now at just under 5A.
