Philips Son-T Pia Plus 250w HPS

High pressure sodium lamps lose output over time, and in most HPS designs that degradation is significant enough to meaningfully reduce yield quality well before the lamp technically fails. The Philips Master SON-T PIA Plus addresses this directly through its Integrated Antenna (PIA) ignition technology, a proprietary design that enables 95% lumen maintenance after 20,000 operating hours. Standard HPS lamps typically drop 15 to 20% within the first 5,000 hours of use. For a grower running the same lamp across multiple cycles, the difference in light output by the third or fourth run is substantial.

Output is rated at 33,000 lumens at 125 lm/W efficacy, placing it among the stronger performers in the 250W HPS class. The 2000K spectrum produces the orange-red dominant light that targets the PAR wavelengths most actively absorbed during the flowering photoperiod, supporting dense, productive flowering across the canopy. The ceramic discharge tube with integrated antenna design also reduces the number of weld points in the lamp construction, improving vibration and shock resistance and contributing to fewer early failures in high-airflow grow environments.

E40 cap fitting. Compatible with 250W HPS ballasts; electronic ballasts are preferred for optimal performance and lamp life. Suitable for universal operating position. Allow the lamp to cool fully before restarting after a power interruption. Covers approximately 0.5 m² of canopy at optimal intensity.
