Query: old bulbs

The bulbs I purchased for mu bug zapper must be old, even though they are in their original package. I have tried everything, including taking them to a hardware store & they do not work. I am too busy to return them, but will probably never purchase anything again through your site. Replacement bulbs should work in something they were made for & they are the correct size bulbs.
