This is one of their old 400lm LED lights. It still works, but the glue formerly holding the glass dome has failed after about 1.5 years.

I wonder why it died today. It's not the first time I played Quake4... damn! I could easily insert a bit of copper/brass foil + thermal goop to restore proper contact. But without an hot-rair station there's no way to give the RAM-chips a treatment that might revive the card.

It isn't even hot here. Room temperature is about 22°C and all case fans are operational. If I had a hot-air thingy I could try to reflow the RAM chips. But a replacement card is much cheaper than getting a cheap hot-air station. Maybe I will keep the card for experimenting with it later.

Something I don't want to see again - EVER.

Initially I was very pleased with these 5 chip 1/2 Watt LEDs I acquired from ebay. For testing I ordered 10pcs of the warm-white type (100,000 mcd @ 100mA), which are shown here, and 10 pcs of neutral/cool-white (120,000 mcd @ 100mA). NONE of the latter have failed so far. I use constant current LED drivers, therefore it shouldn't have been over-current that has killed them. 3 in a row. Now will I use these, or search for equivalent/better SMD types? As it turns out, I won't use the warm-white type at all, it doesn't look good on the kitchen counter at all.

I don't remember abusing this connector. It stopped working today.
