Why is it that when one flourescent tube goes bad they both go out? Does that always happen or just for my tubes?

The tubes in most rapid start twin tube magnetic ballasted fluorescent fixtures are connected in a series circuit so a falure in one tube will cause the other to not light or light dimly. John

Also, similar tubes expire at the end of their useful lives at about the same time. In some cases, one tube might still light, but will suffer diminished output due to staining at the electrode ends. This is normal.
It is better and economical to replace both at the same time in either case.. You're ballast will last longer too.
