No. Fluorescents use argon, not neon.

Fluorescent lights use a variety of inert gases in addition to the
mercury and fluorescent phosphors they contain. Argon is common, but
neon may also be used, sometimes in an Ar/Ne mixture.



Argon isn't just "common" it is the overwhelming choice. The
Ar/Nemixture is rarely encountered. Some special purpose tubes use
krypton, but they are even rarer than the tubes with neon.
