Abstract
A mercury vapor discharge fluorescent lamp is provided that has a mercury barrier. The mercury barrier is effective to inhibit mercury atoms from absorbing into the glass envelope and amalgamating with sodium atoms in the envelope. The mercury barrier is substantially non-mercury absorptive, both when the lamp is on and when it is off.
