The Lumatek 400W HPS & MH Ballast packs performance into a compact design. Its high lumen output produces up to 30% more light than conventional ballasts while running more efficiently, using close to only 400 watts of power. The efficient design runs cooler, requiring no ventilation fans. So you get more light per watt, with the flexibility to run either metal halide or high pressure sodium lamps from the same completely silent ballast. Lamps start up fast in under a minute versus 20 minutes for magnetic ballasts, and soft start technology minimizes current surge. Safety features include cut-out functions for added peace of mind. The powerful yet efficient Lumatek ballast makes your lighting shine with a three-year warranty.

In The Box

  • [1] x Lumatek Digital Dimmable HPS & MH Ballast - 400W
  • High Lumen Output - A Lumatek Digital ballast can produce up to 30% more light output than a conventional ballast.
  • Efficient Running - A 400 watt Lumatek ballasts uses close to 400 watts of power. Seems obvious right.......wrong. Most magnetic ballasts use up to 25% more power than they are rated.  
  • Small Compact Design - The efficient use of electricity has side effects - they run cooler. The unit doesn't require the venting fans seen on other models. 
  • More light per watt - The efficient use of electricity and high lumen output, make Lumatek's lumen to watt ratio very high.
  • One Ballast for two lamps - The intelligent electronics allow either Metal Halide or High Pressure Sodium lamps to be run from the same ballast.
  • Fast Start Up - Lamps reach full brightness in less than one minute, compared to around twenty minutes with a magnetic ballast.
  • Soft Start - Very low start up current.
  • Completely silent - No buzzing or vibrations during start-up or running.
  • Safety - The ballast will cut-out if a short is detected, for ultimate safety.  
  • 3 Year Warranty With proof of purchase


Electronic ballasts offer proven efficiency over dated, magnetic ballasts which were developed over 100 years ago. Independent laboratory results show a full 30% gain in brightness when using a Lumatek Electronic Ballast compared to magnetic options. In traditional HID systems, this means more lumens per watt of energy and, ultimately, more blooms per watt for your plant. Whether searching for the highest output, Lumatek 1000W, cadillac of dimmable electronic ballasts or questing for the smallest, high-quality, air-cooled, dimmable powerhouse known as The Lumatek Mini, the proven strength of the Lumatek line provides you with a multitude of solid solutions.
