Query: bulbs for a Dynatrap

I purchased these bulbs probably about a month ago, but one has gone out already. They are suppose to last for 3000 hours, but one burned out the other is still going, but the ends are starting to turn dark. I thought they were new, but maybe not. I have never had a problem with anything I've ordered before, but this is a little different, especially if they were new. I threw the boxes out, so I don't know and I don't remember the order type.
