New improved Vanguard ballast compatible with 250, 400 and 600w sodium and halide lamps. Work has been done to increase quality and improve features such as high power factor, high conversion efficiency, better heat dissipation, “Soft Start” to improve lamp life, no fan, no resins and totally silent.

Other improved features are

• Progressive lamp ignition
• DSP (Digital Signal Processing) that improves dynamic control and light intensity at each stage of the plant
• Dynamic detection of voltage input, protecting the ballast from damage caused by high/low voltages
• Dynamic detection of current fluctuations, protecting the ballast from short circuits, open circuits and end of lamp life
• Compact design, mini size, weighing less than 1.4 Kg
