We made the test with dome on:

Sorry to hear about your loss. You are now officially a member of this very large club who have lost leds at the same or thereabouts current.

That is so sad. I hope the new U4 flux bins will be more promising. :frowning:

ohh bad news :frowning:

My stock of old XML2 it’s finished… and because these comments do not buy yet!
I think I should buy XP-L instead of XML2 for my next mods :~

Is the XP-L more robust than the XM-L2? I thought they were the same die :quest:

Try a Burn-in at 4amps for 24 hrs. Seems to help.
