Free Gift


  • All metal halide bulbs produce a beautiful shimmering light.
  • Choose 10K, 14K, or 20K metal halide bulb.
  • The Kelvin (K) value of a MH bulb describes the color of the light the bulb produces.
  • Bulbs with a higher K value emit more blue than bulbs with a lower K value.
  • We recommend using a 10K or 14K halide bulb for most reef aquariums.
  • 20K bulbs are often used alone without additional actinic light.

This bulb will work with a standard magnetic ballast, magnetic pulse-start ballast, magnetic HQI ballast or electronic ballast. An great choice for reef tanks 24" or deeper.
