In fact, some historians claim there were over 20 inventors of incandescent lamps prior to Edison’s version (example Tesla) brunomayenfernandez https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899608489 2020-11-07 03:14:21 UTC https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899608489 However, Edison is often credited with the invention because his version was able to outstrip the earlier versions, because of a combination of three factors: an effective incandescent material, a higher vacum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable. brunomayenfernandez https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899615066 2020-11-07 03:23:58 UTC https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899615066 He continued to test several types of material for metal filaments to improve upon his original design and by Nov 4, 1879, he filed another U.S. patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platen contact wires." brunomayenfernandez https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899617798 2020-11-07 03:28:03 UTC https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899617798 This discovery marked the beginning of commercially manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company be again marketing its new product. brunomayenfernandez https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899619728 2020-11-07 03:31:15 UTC https://padlet.com/brunomayenfernandez/4c6fbu2njm23zgzv/wish/899619728
