However the beauty of a Dual Spec is that it also delivers enough blue light to enable you to use it continually though both the Vegetative and Flowering stages and saving on the need for 2 separate bulbs. The Sunmaster Dual Spectrum Lamp is the dual spectrum grow lamp from the ever increasing Sunmaster/Venture Lighting range of of grow lamps. It uses the same technology as the Sunmaster 600W Son-T-Plus 95,000 lumen lamps, but instead of producing the extra 5000 lumens of red light (the Grolux produces 90,000 lumens) they have tweaked the extra output to provide more blue spectrum. Grolux are the original and still probably the best known of all dual spectrum lamps in the UK; made by Sylvania they are basically a HPS sodium lamp with a small amount of blue light added to the spectrum to make the spectrum more suitable for plant growth. Both are highly recommended as good all round growing and flowering lamps although the Sunmaster range now offers much better value for money than the Grolux.
