Despite the fact that Tesla worked closely with Westinghouse, he still retained his own laboratory, and was very happy when he was working there. He continued to make new discoveries, one of which was a lamp that fluoresced, and was actually a forerunner of today's fluorescent tubes. These hit the market some fifty years after Tesla's prototypes! He also investigated many other phenomena including X-rays and a vacuum tube or valve very similar to the Audion or triode valve pioneered by de Forest in 1907.
Nikola Tesla did not invent fluorescent lighting. The modern fluorescent lamp was actually invented by Peter Cooper Hewitt in the early 20th century. Tesla did, however, make significant contributions to the field of electrical engineering and worked on various technologies including alternating current (AC) electricity and radio communication.
Nikola Tesla had inventions that have to do with wireless technology. He did not invent telophone cables.
In 1859 Alexandre E. Becquerel discovered them. People keep claiming Tesla but ... nope. Not even close. He'd write about the phenomenon in 1886 but it was well known and documented by then already.

Tesla did not make the Flourscent bulb. In 1859 Alexandre E. Becquerel did. Tesla wanted to make use of them and discussed them at length decades later. But he did not discover, or invent them.
Nikola Tesla.
That was ready by 1892.
No, Nikola Tesla did not invent the plasma ball. The plasma ball was actually invented by Nikola's brother, Danelei Tesla, in 1894. Nikola Tesla did, however, work extensively with high-voltage and high-frequency phenomena related to plasma discharge.
Nikola Tesla did not invent the laser. The laser was invented by Theodore Maiman in 1960. Nikola Tesla was a pioneer in various fields of electrical engineering and contributed to the development of alternating current (AC) power systems.

During his lifetime, Tesla invented fluorescent lighting, the Tesla induction motor, the Tesla coil, and developed the alternating current (AC) electrical supply system that included a motor and transformer, and 3-phase electricity.
