How a lightbulb works - which one???

How a florescent lightbulb works –
A florescent lightbulb is a glass tube that has two electrodes at either end of the tube, a phosphor lining on the inside and mercury gas inside.
Electrons flow through both electrodes, and interact with the mercury atoms floating inside the lightbulb.
This gets the mercury atoms all excited, but when the mercury goes back to its unexcited state, they release ultraviolet photons.
These photons bang into the phosphor lining of the bulb, and the phosphor gives off visible light.

An electrode is an electrical conductor (takes and gives out electricity I suppose) which is used to make contact with a non-metallic (not metal) part of a circuit, such as mercury in a florescent lightbulb.

A phosphor is a substance that exhibits the amazing power of phosphoresce, in which it sustains glowing after being exposed to energized particles, such as ultraviolet photons in a florescent lightbulb.

I wrote this, and I am having trouble figuring out if it is the long tube or the cool new energy-saving lightbulbs. HEEEEELP!
