Product Description
Ushio High Pressure Sodium Grow Bulbs 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 Ushio HPS lamps have been engineered to constantly deliver 10% more targeted Red Light energy to the maturing plant to promote aggressive flowering. These bulbs are available for 1000, 600 and 400 watt ballasts.
