I’ve two pieces of Convoy S2+ on the 12-mode 5A driver and Samsung LH351D 4000k LED. Both LEDs seem to have developed burn/black spots on the dome.

the lights themselves work fine and the black spots don’t affect the beam pattern. But this is the first time I’ve seen this happen.

That didn’t happened to my s2+ 5000k, but my batteries only provide 3.5A.
Are you sure that isn’t any dust?

It’s not dust. I’ve tried to clean it off with lighter fluid and cotton swab, but it’s still there.

That’s weird. It shouldn’t happen with less than 5A. Anyway you can slice the dome like I did

The S2+ with LH351D is 5A.

Yes, but it’s almost impossible to get 5A due to high vf of lh351d.
