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 is to reduce consumer concerns about efficient light bulbs due to variable quality of products. Those CFLs with a recent Energy Star certification start in less than one second and do not flicker. Energy Star Light Bulbs for Consumers is a resource for finding and comparing Energy Star qualified lamps. In 2011, Republican House members introduced a Better Use of Light Bulbs Act or BULB Act (H.R. 91), which would have repealed Subtitle B of Title III of the Energy Independence and Security Act of 2007. H.R. 2417 failed to pass in the U.S. House. On 16 December 2011, the
