SunMaster 600 Watt (MH) Metal Halide COOL 5500K Grow Lamp
Sunmaster's COOL grow lamps were developed to drive strong vegetative growth. For indoor growing operations requiring 100% artificial lighting, Sunmaster COOL lamps lead the industry with regard to total μmol output in specific spectral ranges to promote strong vegetative growth.
University and 3rd party tested, approximately 50% of the spectral energy of Sunmaster's COOL lamps are found in the blue/violet range between 380nm and 495nm. Partner Sunmaster's COOL lamps with 'SUPER' lamps for the flowering period of the plant growth cycle and "FINISH" lamps at the end of the plant growth cycle in order to maximize yield.
Sunmaster 600-watt COOL lamps are the growers' choice throughout North America and Europe. Chemically weighted with stronger blue wavelengths, the 600W COOL encourages increased internodes while maintaining compact growth. The tailored spectral output promotes a larger leaf area and thicker primary stems.
