Abstract

Sodium vapor discharge tube provided with a rare gas filler consisting of neon with an addition, characterized by the fact that the addition consists of 0.1% to 0.3% xenon and 1% to 4% of helium, the percentages being expressed in percentages per volume of neon, and that the interior facing of the discharge container is made of a borate-based glass that does not substantially change the color.
