The Philips Son‑T E 400W HPS Lamp – SE is a high-pressure sodium bulb celebrated for its potent performance in horticulture, especially during flowering and late vegetative growth. With a colour temperature around 2000 K, this lamp emits a warm, red-rich spectrum that promotes robust flowering while still supporting structured canopy development through added blue from its xenon start gas. It’s a single-ended E40-base lamp designed for reliable plug-and-play use in standard horticultural reflectors.

Ideal for commercial and serious hobbyist growers, this Philips lamp stands out for its energy efficiency, long lifespan, and consistent output, making it a trusted workhorse in controlled-environment agriculture. The integrated antenna (PIA) and clear tubular bulb ensure stable performance over thousands of hours, with lumen maintenance exceeding 94% after 2,000 hours. Its simplicity, efficiency, and reliability make it a valuable addition to any HPS grow light setup.
