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.

Equal in quality to the Son-T Agro, the Son T Plus is one of the most lumen efficient lamps on the market.

The Philips 1000 watt Son-T has a similar colour rendering of that of it's other Son-T family members.

It must be run on a Lumatek Ballast or a 'Euro' style ballast
