XM L2 U2- 0 D dies at 5,3 Ampere


bad news at the best tint after dedoming.

sma and me do some tests after I kill some Leds …

First thinking was that something wrong with dedoming or reflowing,but…

I want to put in a TN 32.

We made the test with dome on:


The Vf is crazy ,too.

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

ohh bad news Sad

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 :~

Sorry for my bad English…

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.
