This lamp is a high output bulb for both vegetative
and flowering stages.
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.
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.
