Allen Productions has been working on a New LED Retrofit Kit Designed to Replace MSD / HMI Lamps in Moving Head Spot or Wash Lighting Fixtures 150-Watt to 1200-Watt. If you are a touring company, a rental house, or have a permanently installed rig of moving heads, this retrofit is for you! IT WILL VOID YOUR WARRANTY because it requires a bit of modification of your light fixture to fit the LED module into place, and replacing your existing heavy ballast and igniters in the fixture with an LED ballast.
