A lamp () has a lamp envelope () having a body () with a bottom () having a lead-in accepting channel (); a seat () formed with the bottom () adjacent one of the lead-in accepting channels; a light source capsule () having two electrical lead-ins () extending therefrom and through the lead-in accepting channel (; and an electrical contact () having a first depending leg (), an intermediate transverse portion () including a seat engager () adapted to cooperate with the seat (), and a projecting leg () extending away from the intermediate transverse portion () and along a side () of the bottom (), the first depending leg () being in mechanical and electrical contact with one of the lead-ins ().

A dispenser () for a volatilizable material has a first member () that is substantially cup-shaped with a given diameter (X) and with a given depth (Z) and having a first peripheral flange () having a first diameter (D). A second member () has a second peripheral flange () with a second diameter (D) greater than the given diameter (X). The first peripheral flange () and the second peripheral flange () are in intimate contact thereby defining a volatilizable material chamber () between the bottom () of the second member () and the bottom () of the first cup-shaped member (). A volatilizable material () such as liquid mercury is placed in the chamber; and a hermetic seal () is formed between the first and second flanges. When installed in a fluorescent lamp the volatilizable material is released by heating the dispenser with RF current. The material is released when the vapor pressure within the dispenser reaches about 20 atmospheres. For mercury, this pressure is achieved when the dispenser reaches about 600&#xb0; C.
