Most of a Dual Spectrum Grow Lamps output is in red light. However, the beauty of this type of lamp 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.

Greens stock two different brands of dual spectrum lamps: Sunmaster and Grolux. 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.

The Sunmaster Dual Spectrum Lamp is the dual spectrum grow lamp from the ever-increasing Sunmaster/Venture Lighting range 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 from the blue end of the spectrum.

Sunmaster also do a 1000W dual spectrum lamp which replaced their pure sodium lamp and represents the first 1000W dual spectrum lamp on the market.
