High pressure sodium bulbs and metal halide bulbs emit different color spectrums of light. Figure 4: High Pressure Sodium Lamps 2.3 Quartz Metal Halide (QMH) Metal Halide lamps have an efficacy of 80-115 lumens per watt and have a life between 10,000-20,000 hours. When you pass an electric arc through these gases, you are forcing them to ionize. At this early stage, the sunlight helps the plants grow taller and stronger. H3.
