Building an 18500/AA light?

I can’t stand MM either. Pencil trick won’t work AFAIK. That link is the driver I’m talking about. I’ve been using one with a 14500 for a while without issue but IIRC Simon recommended against it. Maybe just because of no LVP I’m not sure.

I have a pic and current measurements at the LED from a modified driver at the end of the what did you mod thread.
