Phosphorescent Lamps
Tesla’s contribution didn’t end with developing the electrical system, he developed a wireless light tube. He captured high frequency electric fields in a cordless low-pressure gas discharge lamp, which created enough power to light a room. These lights were slower to emit lights that fluorescent lighting and keep glowing for a while after the light is shut off. Tesla had been working on wireless power for some time, and by 1890 he could light phosphorescent tubes in his lab. Fair crowds were amazed at this new technology. It was proof that a new scientific age had arrived. Tesla’s tubes inspired fluorescent lighting, although Tesla himself never produced a commercial version of his tube.
