A sodium vapour lamp does not include a capacitor in its construction. Any capacitor associated with this type of fixture will be found where the ballast is located and not in the lamp itself.
Similiar to a flourescent light. The ignitor provides a high voltage potential to excite the sodium gas within the bulb.

To install a bathroom light fixture, first turn off the power to the existing light fixture. Remove the old fixture and disconnect the wires. Install the new fixture according to the manufacturer's instructions, making sure to connect the wires correctly. Secure the fixture in place and test it before turning the power back on. If you are unsure or uncomfortable with electrical work, it is recommended to hire a professional electrician.

Volatility, vapour pressure
No, it is not recommended to use a T5 lamp in a T4 fixture. T5 lamps are designed to work with T5 fixtures, which have different dimensions and electrical requirements compared to T4 fixtures. Using a T5 lamp in a T4 fixture can lead to compatibility issues and may cause damage to the fixture or lamp.
Old steam engines used the principle of vapor pressure doing work.
