Key Differences

Fluorescent lighting technology involves a phosphor coating inside glass tubes that emit light when excited by ultraviolet light produced by electrified mercury vapor. On the other hand, neon lighting relies on the characteristic glow of electrified neon gas, contained within sealed glass tubes, which emits a bright reddish-orange light.
Fluorescent lights are commonly used for broad lighting applications such as in offices or schools due to their energy efficiency and long lifespan. Whereas, neon lights are favored for signage and decorative purposes because of their vibrant colors and ability to form intricate designs.
The energy efficiency of fluorescent lights is significantly higher, making them more suitable for areas requiring prolonged illumination. Neon lights, while less energy-efficient, provide a unique aesthetic that is irreplaceable in certain design contexts.
Fluorescent lights can emit a wide spectrum of colors by altering the phosphor blend inside the tube. In contrast, neon lights primarily emit a bright red-orange glow, but can display different colors by using different gases or colored glass.
The installation and maintenance of fluorescent lights are generally simpler and more cost-effective, supporting their use in commercial and residential settings. Neon lights require more specialized skills for installation and maintenance, reflecting their niche application in advertising and artistic installations.
