This Metal Halide bulb emits more of the blue light spectrum (even though it looks white when going). This "blue" light is beneficial for great leaf formation and closer inter-nodal spaces (the gap between leaf sets). It makes for a more compact plant.


Metal Halide Conversion bulbs run on both H.P.S ballasts or most M.H. ballasts. Ideal for keeping a mother plant in a vegetative state, raising cuttings, or using it throughout the vegetative stage.



  • Metal Halide/Conversion bulbs can sometimes take up to 5 minutes to ignite when run on an 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 wattage. For example, only run a 600-watt MH conversion bulb on a 600-watt ballast.
