Yes, me too Sad

I have have received the leds and reflowed them (both 5000K R8000) on my boards (on which they are going to be tested until your boards will be available), but I need 2 hours for the actual tests, and 3 more hours for the write-up. I’m not sure where to find those hours in the next week.

Thanks for the test Djozz,
Mine was dying at 8A, but still lit. The damage pattern truly depends on how the pads are cooled. The burnt always started from the hottest point. This LED should create a better nice beam pattern with it’s rounded rectangular hotspots.

Thanks for the tests. I cancelled the order I had placed after I saw that the dies didn’t extend to the edge, and I’m glad I did. These might be fine for some applications, but it’s not what I was looking for.
