I bought this bulb http://www.onestopgrowshop.co.uk/grow-lights/lamps-en/sylvania-grolux-600w-hps-lamp-90-000-lumens.html#.UklZ4RDG7EB


This is the description:
How the Sylvania Grolux 600w HPS lamp works: The Sylvania Grolux 600w HPS lamp is a dual-spectrum lamp with a high 90,000 lumens output. The Sylvania Grolux produces light mostly in the orange/red part of the spectrum for excellent flowering but also produces some blue to make it also usable the vegetative growth stage.

Does anyone have experience with this type of bulbs?
The shop I'm using for a while now is listing these grolux type of bulbs as most sold bulbs and best buys.

Would I benefit noticeably by buying a pure MH and HPS lamps?
