LightEnerG™ Hybrid MH/HPS Bulbs are enhanced-performance, high-output grow and flowering lamps. Composed of both high pressure sodium (HPS) and metal halide (MH) cores, these lamps provide the reds of an HPS bulb and the blues of an MH bulb. This full spectrum light allows you to use just one bulb throughout the entire growth cycle. By emitting 117,000 initial lumens with a 12,000-hour life rating, it’s able to last multiple cycles while producing excellent results. Use with any 1,000 W HPS ballast.
