Abstract
This invention relates to the lead-in wires used in association with press seals in soda-lime glass for achieving electrical connection into the sealed envelope of a compact fluorescent lamp. The lead-in wires have a core comprising nickel and iron. A metallic plating on the core prevents formation of Fe.sub.2 O.sub.3 during lamp sealing. The invention improves lamp life by maintaining seal integrity at elevated seal temperatures.
