Box is slightly damaged (pictured)

HORTILUX Metal Ace (converts HPS to metal halide) conversion lamps are metal halide lamps that operate on high pressure sodium systems. A one-dimensional lighting system is easily and economically converted into a complete (metal halide/HPS) growing system, providing the full range of spectral energy required for all stages of plant growth and development. These lamps are 100% lead-free.


  • Use only with ballast for ANSI S51 lamps
  • Use in enclosed fixture only
  • Unscrew the HPS lamp and screwin the Hortilux Metal Ace lamp of equal wattage.
