I once used an ESU spiral bulb that worked but would make a little rattling sound when it was turned upside down. Since yours isn't lighting, though, something is obviously wrong with it and you should take it back. If there are a bunch of 5.0s in the store, take one that looks like it's been handled the least (hasn't been opened). When I used to buy red heat bulbs, I was amazed at how some of them had been opened (seal was broken). I also once watched the staff at a petstore put out new stock---bulbs had just been thrown into a basket, some at the bottom, with other products. Very easy for them to become damaged...
