Philips Son-T Agro 400w HPS Bulb

Philips Master SonT Agro 400w HPS are the perfect solution for landscape and security applications where lower light levels are desired. Philips high pressure sodium lamps have superb energy savings and low maintenance costs. They also have a very long lamp life and excellent lumen maintenance.

These bulbs are optimized to produce high levels of red and yellow light spectrum, but do not contain the same levels of blue light spectrum that most HPS bulbs traditionally contain.This makes them an excellent fruiting/flowering bulb, but the results of using them in vegetation may differ from those expected from traditional HPS bulbs. I.e. stem elongation/larger inter-nodal spacing may occur.

This bulb can still produce satisfactory vegetative growth. However, would we recommend a Metal Halide/Conversion bulb as ideal for use in the vegetative stage, as they are optimized for the best results for vegetation.
