SolarMax lamps are specifically designed for horticultural applications. ISO certified engineering and manufacturing processes assure high quality and optimized performance. SolarMax grow lamps are designed with the grower in mind. As plants approach maturity they require less Blue Light and depend more upon radiation from the Red portion of the spectrum between 610 nm - 720 nm. The SolarMax HPS lamps have been engineered to constantly deliver 10% more targeted Red Light energy to the maturing plant to promote aggressive flowering.
