Sylvania GroLux HPS 600 watt

The High Pressure Sodium Grolux Lamp has been specifically developed for horticultural applications and optimum plant growth. Effectively the same as a normal sodium lamp, Grolux lamps have been colour adjusted to provide a much broader spectrum of light (notably in the blue spectrum) which makes them perform exceptionally well in both the vegetative and flowering stages.
