High pressure sodium lamps

“White Son”, SDW-T (35–100 W)

The lamp has a colour temperature that lies close to the light from an incandescent lamp and reproduces most colours in an excellent manner. Other advantages are high efficiency and long lamp life.  

Limitations

These high pressure sodium lamps cannot be dimmed. They have an ignition time of approx. 4 minutes and the restart of a hot lamp is up to 2 minutes.  

Other high pressure sodium lamps normally have a high luminous efficacy in combination with a low colour rendering index.

Limitations

As above.
