Best Answer

The voltage present on the secondary side of the ballast (transformer) varies as to the type of fluorescent tube or bulb that is in the fixture. The voltage will always be higher that the applied line voltage that supplies the ballast.If the fluorescent bulb screws into a lamp type of fixture, then there is no way to measure the voltage at the bulb as the tube and ballast are a combined sealed unit.

When a fluorescent bulb burns out should you be able to smell the gas?

No, you should not be able to smell any gas when a fluorescent bulb burns out. Fluorescent bulbs contain a small amount of mercury vapor, but it is contained within the bulb and should not be released into the air unless the bulb breaks. If you do smell a strong odor, it could indicate a different issue and you should contact a professional.
