The MASTER GreenPower 600W is a high-performance HPS lamp designed for powerful performance during flower. Emitting up to 90,000 lumens with a bloom-enhancing 2000K spectrum, it promotes robust bud development, increased trichome production, and deeper canopy penetration. With a finely tuned spectral output that delivers photosynthetic efficiency, it’s designed for longevity and reliability with up to 30,000 hours of consistent output. Pulling 600W, it fits standard E40 sockets — meaning it’s compatible with most 600W ballasts and reflectors. Whether you need an option for a single flower room or you’re expanding a multi-room setup, this quality lamp delivers proven results. Need a bulk solution for commercial-scale flowering? The MASTER GreenPower Xtra UNP/50 provides the same efficiency in a cost-effective 50-pack. For growers looking to step up performance with added durability and output, the MASTER GreenPower Plus Mogul offers enhanced lumen maintenance and longer lifespan.
