ABSTRACT:
A lamp base for a dual-leg lamp is provided with at least one oversized leg mounting hole that permits relative movement of the lamp legs during temperature driven expansion and contraction. In one embodiment, only one leg of the lamp is glued to the lamp base. The absence of glue on one leg permits essentially free movement of the non-glued leg with respect to the base. In those embodiments that include only a single oversized leg mounting hole, the leg disposed within the oversized leg mounting hole is not glued so that the leg is free to move within the oversized hole. In those embodiments in which both leg mounting holes are oversized, it is acceptable for either (or both) of the legs to be non-glued.
