What the difference between neon and cathode (case mod)?

Question

What the difference between neon and cold cathode lights ?

Answer 1

A neon is a type of cold cathode light. The neon gas directly emits the classic red-orange color. Some cold cathode lights use different gas fills which emit UV. The inside of these are coated with a phosphor that glows when excited by the UV. The color of the light is dependent on the mix of the phosphor. Practically any color of the spectrum is possible.

Answer 2

As far as I know, cathodes are cold and neons produce heat.
