PHILIPS 400 WATT SON-T AGRO The Philips 400 watt Son-T Agro grow lamp has a specially tailored spectrum output which is optimised for plant growth. A 30% increase in the blue content of the spectrum (added Xenon) ensures that more leafy, vegetative growth is achieved – higher yields of better quality plants.
These lamps have superb energy savings and low maintenance costs. They also have a very long lamp life and excellent lumen maintenance.
The Original HPS lamp and still one of the best out there.
