MH Conversion Bulb 400W Nutrients Growers aiming for strong rootMetal Halide Conversion bulbs can sometimes take up to 5 minutes to ignite when run on a HPS (High Pressure Sodium) ballast. Do not be alarmed if the bulb does not ignite immediately, as it may take a couple of minutes. If you are using a digital ballast that can be dimmed DO NOT dim or supercharge the MH conversion bulb. This may cause damage to the bulb. It can only run on the same setting as the bulb itself. The bulb wattage must match the ballast
