gHID vs Magnetic HID

Please fill required fields

Magnetic ballasts have been the primary ballast used in HID lighting for decades. As lighting and electronic technology has become more sophisticated.  The magnetic ballast has become less optimal for HID lighting. Yet magnetic ballasts are still widely used.

Genesys Global gHID ballasts have considerable advantages over magnetic ballasts:

  • gHID consumes up to 75% less energy because it operates at an ultra-high frequency, which drives greater light output at lower wattage.

  • gHID ceases to consume power when the lamp burns out; magnetic ballasts continue to strike, which consumes power and kills the ballast.

  • gHID yields greater mean lumen output and produces clearer, brighter light with a metal halide lamp

  • gHID offers 6KV non-dissipative power surge protection, and withstands more than 85% of power outages without losing light

  • gHID also has dimming capability with little reduction in light quality
