Product information

Description

The Philips MASTER SON-T PIA Plus 400W E40 is a high-pressure sodium discharge lamp designed for applications that require high lumen output and a warm colour rendering. The lamp delivers 55,800 lumens at a warm 2000 K colour temperature from a clear tubular outer envelope. With a rated power of 400 W, an output current of approximately 4.5 A and an AC input range of 85–115 V, this lamp is built for continuous operation in industrial, street and specialised horticultural installations where strong, long-range illumination is needed. The lamp measures 48 × 48 × 283 mm and uses an E40 screw base for easy installation into compatible luminaires.

Advantages

This sodium discharge lamp offers very high luminous efficacy for its class, producing a large luminous flux while maintaining a warm spectral output around 2000 K. The clear tubular outer bulb provides good directional light and helps maximise usable light output. The lamp is specified for reliable long-life operation under typical high-intensity discharge conditions, and its E40 screw base ensures compatibility with many industrial and street luminaires. The combination of high lumen output and warm colour temperature makes it suitable where visual comfort and long-distance illumination are both required.

Suitable for (tasks / use cases)

  • Street and roadway lighting requiring high lumen output
  • Industrial halls and outdoor site lighting
  • Horticultural installations where warm-spectrum high output is acceptable
  • Large-area floodlighting and security illumination

Key specifications

  • Rated power: 400 W
  • Luminous flux: 55,800 lm
  • Colour temperature: 2000 K (warm)
  • Base type: E40 screw
  • Envelope: clear tubular outer bulb (silver transparent appearance)
  • Physical dimensions: approximately 48 × 48 × 283 mm
  • Operating current: ~4.5 A
  • AC input range: 85–115 V

How to use

Install the lamp into a compatible luminaire with an E40 socket and a ballast or gear suitable for high-pressure sodium lamps of this rating. Ensure the luminaire and ballast are rated for 400 W operation and for the specified input voltage range (85–115 V). Allow appropriate warm-up time after ignition for the lamp to reach its full luminous flux and stable colour point. Observe manufacturer guidelines for safe installation, secure mounting of the luminaire, and wiring by a qualified electrician when required.

Usage recommendations

For optimal lifetime and performance, use with a properly rated ballast and in fixtures that provide adequate heat dissipation and protection from direct water ingress. Avoid frequent on/off switching to prevent reduced lamp life. Select luminaires and control systems that match the lamp’s warm colour temperature and high lumen output for intended visual tasks.
