Sylvania 400 W GroluxSylvania luxury version!
This high-quality sodium lamp from the house of Sylvania is perfectly suitable for the hemp cultivation!
The outstanding cost effectiveness as well as the explosive plant growth speaks in favour for Sylvania!
The Grolux-series differs from the SHP-TS especially through a longer lifetime by the same intensity.
By comparison to the Sylvania SHP-TS lamps the Grolux-models have a higher proportion of blue. Due to that the lamp is also conditionally suitable for the growth periode.
The main colour spectrum of the Sylvania Grolux 400 W is in the red and yellow range, which is required for the bloom periode.
For the usage of a lamp you will need a suitable ballast - (HPS) - and an E40 socket.
Never ever touch the lamp with your bare hands on the glass. Body fat can affect the intensity and lifetime of the lamp!
