It’s past the return date so I’ll need to put it in the electric skillet to reattach the LED.

Sounds like a good time to replace that CW XPL. I’ve been very happy with the quality of light from the ~3000k 80CRI XPL HI. Its not as nice as the 80CRI XPG that Malkoff used as those looked virtually the same as a halogen while the XPL HI almost has a “brown” tint. But still very decent and only noticeable when comparing to a 4000k or higher 219 or sst-20.

You think it might have overheated? Also check if it has enough thermal paste underneath the LED board.

I seriously doubt it overheated.I've not had it on turbo or high except for a short test on each setting the day I received it.

I had 4 x Sanyo XX in it while it sat unused in my SUV console since Oct 16th till 2 days ago.

So it's a 20mm MCPCB with domed Cree XPL.What is my" best" option for replacement without touching anything else in the light?

I like 6500K but 5000K is OK too.

I had the same bad solder on my SF11 and so did someone else in another thread about that light.

That is no good sign. The types of emitters are endlessly whatsthepoint. It's a personal thing. I would suggest going to Intl-outdoor.com to see some options.

The SF11 was my only working 4 x AA .My other one,a Nitecore EA41,went bad when the copper tops in it leaked.I see a thread on rebuilding the EA8 and another on the EA41 but I don't see the exact procees of getting the parts out and the tools needed.

Any thoughts on LEDs from Mountain Electronics LLC while I'm ordering a pair of black ShockLi 26650?

OK,I got the SF11 working using the electric skillet method to reattach the Cree XPL to the aluminum

MCPCB.

I think this was the 2nd time the skillet was used in the 10+ years we have it.

Added high quality thermal paste while I was at it.
