Detailed explanation-1: -Unlike the regular incandescent light bulb used earlier, a halogen (such as iodine or bromine) is used in the bulb. This improves the life of the Tungsten filament. Also, the illumination is better as the halogens have atoms distributed so the light produced covers a better distance.
Detailed explanation-2: -Latimer made a major contribution to the development of electric lighting by inventing a longer-lasting filament. But he did not invent the lightbulb. Thomas Edison is regularly identified as the inventor, though that claim is itself often challenged.
Detailed explanation-3: -Lewis Latimer improved the standard of living by primarily making electric illumination effective, and then making it affordable for households with average financial capacity. Latimer made this possible by patenting a filament filled with carbon that was applied to light a bulb.
Detailed explanation-4: -Lewis Howard Latimer (1848–1928) was a Black inventor and patent draftsman who improved Thomas Edison’s original invention by patenting the use of a carbon filament which made possible the widespread use of electric light in public and at home.
