- Sodium is an element with strong excitation ability and can produce strong yellow light when excited.
- Sodium has a very high thermal conductivity. It can effectively transfer this heat to avoid overheating the lamp and extend its service life.
- Sodium has good chemical stability and is not easily affected by oxidation, which can ensure the lifespan of lamps.
- The price of sodium is relatively low, which can reduce the manufacturing cost of high-pressure sodium lamps.
