Noble gas as in other metallurgical processes and in the production of silicon for the semiconductor industry. Noble gases are commonly used in lighting because of their lack of chemical reactivity. Argon, mixed with nitrogen, is used as a filler gas for incandescent light bulbs. Krypton is used in high-performance light bulbs, which have higher color temperatures and greater efficiency, because it reduces the rate of evaporation of the filament more than argon; halogen lamps, in particular, use krypton mixed with small amounts of compounds of iodine or bromine. The noble gases glow in distinctive colors when used inside gas-discharge lamps, such
Phase-out of incandescent light bulbs emission total is 564.7 million tonnes), a saving of approximately 0.14%. There have been some initiatives to encourage people to switch to compact fluorescent lamps ahead of the phase out. Australia will ban halogen light bulbs from September 2020. In February 2007, then Climate Change Minister David Parker, Labour party, announced a similar proposal to the one in Australia, except that importation for personal use would have been allowed. However, this proposal was scrapped by the new government in December 2008. In Argentina, selling and importing incandescent light bulbs has been forbidden since 31 December 2010.
