A cold cathode fluorescent lamp (1) has feedthrough pins (5) made from molybdenum or a molybdenum alloy that form a glass-metal seal (6) with a glass composed of 55-75 wt. % SiO.sub.2, 13-25 wt. % B.sub.2O.sub.3, 0-10 wt. % Al.sub.2O.sub.3, 5-12 wt. % alkali oxides, 0-3 wt. % alkali earth oxides, 0-5 wt. % ZrO.sub.2, 0-10 wt. % TiO.sub.2 und 0-5 wt. % remaining oxides. The lamp has hollow cathodes (4) made from a material of the group molybdenum, molybdenum alloys, niobium, niobium alloys, and the lamp is manufactured in a compact form using conventional manufacturing parameters, and the resulting lamp has crack free, long-term vacuum-tight glass-metal seals.
