As you might recall, the incandescent bulb phase-out stems from the Energy Independence and Security Act of 2007 (EISA 2007). A section of this Act has adopted the title of Incandescent ban over the last few years, except it is not really a ban at all.
The next big change in the incandescent bulb came with the invention of the tungsten filament by European inventors in 1904.
