Abstract
A conductive link maintains the electrode of a fluorescent lamp and a conductive electrode guard at the same electrical potential to reduce lamp power dissipation. The conductive link may be a fuse wire to protect the lamp ballast from excessive current upon electrode failure and shorting to the electrode guard.
