Additional Info The Gavita DigiStar ballasts have been developed to drive a wide range of HPS/MH lamps. They are manufactured using the highest quality components needed for the high output frequency. The result is a very cool digital ballast with optimal output specifications, absence of acoustic resonance and a very long life. Output can be boosted up +15% (1000W model).
Digital ballasts have a lot of advantages over traditional magnetic ballasts: They are more efficient, adjustable, generate much less heat and provide a stable output regardless of the input voltage. Using a magnetic ballast you will lose light when your mains voltage is less than optimal.
To build a stable digital ballast you need high quality components. This is especially the case if you want to reach the high frequencies required to prevent acoustic resonance in your arc tube, which can lead to premature lamp failure. DigiStar ballasts are built using the highest quality components. This results in a ballast that outputs a very high frequency (preventing acoustic resonance) but also a very cool ballast. The DigiStar is cooler and performs at a much higher frequency than comparable A-brand ballasts.
The DigiStar ballasts are adjustable over a wide output range, enabling you to dim or boost your lamp. With 15% on the 1000W models you are guaranteed to generate the highest output available.
To ensure a long lamp life we have built in soft-dim. When you adjust your output it takes 60 seconds to gradually dim or boost per step. This process is so gradual that your eyes won't even see the difference. Multiple output power enables you to use different lamps with a single ballast: The 1000W model for 600W and 1000W lamps.
The internal microprocessor ensures the highest possible output in any circumstance.
