Do you need a tombstone for a light fixture?
In general, it will depend on the ballast system in place. For example, if you are operating a fluorescent fixture T5 or T8, you will need a shunted tombstone. When working with a T5 or T8 fixture operating under a rapid start, dimming, or programmed start ballast, you will need an unshunted.
