Sunmaster Dual Spectrum lamps from Venture Lighting. The Sunmaster Dual Spectrum range has been developed to create one lamp that can be used during the vegetative and flowering stages. The new photonic feature gives enhanced spectral stability at lowered, overdriven and fluctuating power levels. This makes them ideal for variable output power packs, giving the plants the optimum spectrum for growth with each power mode.
They are predominately flowering lamps with a small percentage of the blue spectrum which eliminates the need to change lamps during cycles and adds the extra spectrum to the flowering cycle. The manufacturers say it delivers 10% more light than standard high pressure lamps.
For use during the vegetative and flowering stages.
