A lamp that produces light by heating up a filament of wire inside a bulb with an electric current. Because the filament, usually made of tungsten, would burn from the heat, the bulb is filled with a nonreactive gas, such as argon, which protects the wire from burning. Comparefluorescent...
Compact fluorescent light bulbs (CFLs) are next on the list for a potential ban. In December 2022, the Department of Energy proposed a new rule meant to double the current minimum light bulb efficiency level to over 120 lumens per watt. If it actually comes to pass by the end of 2024,...
Incandescent light bulb efficiency is improved by: (1) modifying the surface micro-structure of a lamp filament in such a way as to increase the emissivity in the visible region of the spectrum without significantly increasing this quantity outside this spectral region, or suppressing the emission...

In December 2022, the Department of Energy proposed a rule that would more than double the current minimum light bulb efficiency level, to over 120 lumens per watt for the most common bulbs. That would go into effect by the end of 2024 andeffectively ban CFL bulbs. ...
