How to use
Install the lamp into a compatible fixture rated for high-pressure sodium lamps and for the E40 base. Ensure the fixture is switched off and cooled before replacing or installing the lamp. Use appropriate ballast or control gear specified for 400 W HPS operation and follow the luminaire manufacturer’s instructions. Allow the lamp to reach full output after ignition; high-pressure sodium lamps typically require a warm-up period to stabilize lumen output and colour.
Usage recommendations
Operate the lamp in fixtures that provide adequate heat dissipation and protection from moisture and mechanical damage. For outdoor or critical installations, consider routine inspections and replacement planning to maintain consistent illumination levels. Do not use the lamp with incompatible electronic controls or dimmers unless explicitly stated by the ballast or luminaire manufacturer.
