A cold cathode fluorescent lamp () has feedthrough pins () made from molybdenum or a molybdenum alloy that form a glass-metal seal () with a glass composed of 55-75 wt. % SiO, 13-25 wt. % BO, 0-10 wt. % AlO, 5-12 wt. % alkali oxides, 0-3 wt. % alkali earth oxides, 0-5 wt. % ZrO, 0-10 wt. % TiOund 0-5 wt. % remaining oxides. The lamp has hollow cathodes () 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.
