The Philips Son-T Pia is a high-quality sodium vapor bulb that is made for the blooming phase of the plants. With its 400 watt and 55.800 lumen, it is a suitable bulb especially for the utilization in greenhouses and propagators. Thanks to the Pia-technology (Philips Integrated Antenna), a considerable higher average durability is achieved, since this technology forgoes any mechanically movable components in the construction of the bulb.

This makes the Philips Son-T Pia more simple and shock-resistant than other sodium vapor lamps and reduces the early failure rate by the modified ignition technology. Additionally, the pressure of the discharge tube of all Pia sodium vapor lamps has been reinforced, which increases the luminous flux. That way the Philips Son-T Pia reaches a luminous efficacy of up to 139 lumen per watt. With its red/yellow color-spectrum (2000 kelvin) this bulb gives the ideal light for the blooming phase because it supplies the plants with the essential wavelength.
