I am willing to bet that the bulbs you got were the ones that I returned. Was the box for the bulb unglued?
The bulbs look to be returned to Amazon by someone that damaged the connectors and then returned them. Amazon in their questionable wisdom, did not look at the return, put it back on the shelf and then sent it out to the next sucker.
I ordered 3 bulbs and then returned 2 of them for this very reason. I bet you got them next.
I also found that the connectors break off the light very easily. I had to solder one connector back on to each of the bulbs I accepted.
