Anyone ever had issues with the XR-E Q5 LEDs from Deal Extreme?
I've seen mention elsewhere that the PCB was lower quality...but are there any cases of people having problems with them? It's not like they are subjected to physical abuse or anything...they are soldered once and then just sit there and conduct.
If the solder pads are hard to solder to, or the connections/heatsinking fail however, that is a different matter and obviously paying more would be worth it.
I've bought 10 or so and all were spot on. 6 of them are in my home light fittings and have been since 25/09/2008. Some had a very slight green tinge to them when first installed but that has dissapeared at some point over the last 12 months, not a flicker otherwise
