Quick Summary

A krypton-filled lightbulb is a type of electric incandescent lamp. It features a metallic filament enclosed within a glass shell. This shell is filled with an inert gas, such as krypton.1

The development of the krypton-filled lightbulb is credited to Imre Bródy, a Hungarian physicist. He worked in a research laboratory in Budapest and, along with colleagues, focused on producing krypton and developing the krypton lamp. The patent for this invention was granted in 1930.2

Krypton itself is a rare, colorless, and odorless gas belonging to the noble gas group. It is found in Earth's atmosphere and was discovered in 1898. Krypton is used in various types of lamps, including electric and fluorescent lamps.3
