Sunmaster 600w-400w HPS

SUNMASTER High Output HPS Lamps are High Pressure Sodium lamps designed to deliver 10% more light than standard HPS lamps. This extremely energy-efficient plant grow lamp provides more energy which is essential for optimized photosynthetic response.

The Sunmaster Super HPS is the highest output HPS bulb available providing much higher Photosynthetic Active Radiation (PAR) for plant photosynthesis. This bulb will work on any HPS ballast.
