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.
