The ballast that runs it.  Are you considering buying an entire new light or just a bulb, if so then you need to figure out whether you have a T10 or T8 unit .

Thanks for you response

Yes, the ballast is a major factor. The ballast instructions/specs should be able to tell you what it can run. Physically though they are two different size bulbs. T10 means 10/8ths of an inch diameter and T8 means 8/8ths or 1inch tubes.
