Abstract
A tungsten-halogen lamp employs a slidable getter which automatically positions itself in the lowest, and thus, coolest, portion of the envelope where it is most efficient. This feature allows such lamps to be burned in a horizontal or vertical mode; the vertical mode including both base down and base up positioning.
