Offering Unbeatable Yields & Unmatched Quality

A new milestone in CMH technology, the Master Pursuit 500w CMH all-in-one fixture is a must-have. With higher efficiency compared to traditional 315w lamps, the 65% increase of light energy is a more economical alternative with nearly the same output as two 315w CMH lamps used in the 630w CMH fixtures. Providing an average of 1000 μmol/s of usable photon flux, the newly designed components and safety features guarantee a high-quality product. This next-generation technology has increased performance and overall reliability for a lighting system you can count on.

Grower's Choice Master Pursuit 500W Features

  • AI Ignition Control
    This revolutionary feature, unique to our products, makes GC Series Digital Ballast the safest and most reliable ballast when used in automated multiple lamp applications. When multiple units are connected to the same mains circuit, our integrated Ignition Control software will completely balance the electrical draw by igniting one lamp at a time to prevent electrical surges and spikes that can overload the mains circuit and trip circuit breaking systems. For further efficiency, this feature is activated alongside our 'Soft Start Technology'.
  • Soft Start Technology
    Soft Start Technology prolongs lamp life by stopping the current rush to the lamp and preventing lamp overload. When the ballast is started from cold there will be a 3-second fixed delay before ignition. After ignition, there will be a series of random 0-2 second delays before full brightness is reached after approximately 3-5 minutes. SoftStart Technology is also activated when increasing and decreasing power to the lamp using the 'Smart-Step' feature.
  • Re-Strike of Hot Lamp after Mains Failure
    The GC Series Digital Ballast uses a timed re-strike system that prevents the ballast from re-striking a hot lamp after a power failure. If a hot lamp is detected, the re-strike will be delayed for 60-second intervals until the lamp has cooled sufficiently to be re-ignited. Re-ignition is then controlled by 'SmartStart Ignition Control' and 'Soft Start Technology' software.
  • Lamp Compatibility
    The GC Series Digital Ballast is suitable for use with all good quality HPS, Metal Halide, and Ceramic Metal Halide lamps. For a guaranteed perfect match and the best results, we recommend Grower’s Choice horticultural lamps. Grower’s Choice lamps are optimized for use with high-efficiency electronic ballasts with adjustable output.
  • High Energy Efficiency
    The GC Series Digital Ballast is up to 30% more efficient than standard magnetic ballast producing more lumens of light per watt of consumed energy. Efficiency does not diminish and is maintained for the entire life of the unit.
  • Automatic Frequency Adjustment
    The GC Series Digital Ballast automatically adjusts its output frequency to maintain a constant output regardless of input power fluctuations and aging lamps. This also prevents 'lamp flicker'.
  • Full Circuit Protection
    The GC Series Digital Ballast uses a sophisticated software controlled circuit breaking system that is not seen in other manufacturer's ballasts. The system protects against a series of faults including; Open Circuit Protection, Short Circuit Protection, Over Voltage Protection, Under Voltage Protection, and Over Temperature Protection. On ignition, the ballast performs a 3-second test of the circuit and in the event of a fault, the ballast will go into protection mode to avoid damage to the ballast and lamp.
  • Running Temperature
    The GC Series Digital Ballasts' unique case design acts as a superior heat sink making the ballast extremely cool running without the need for internal fans.
  • RF Shielding
    The GC Series Digital Ballast has superior RF Shielding with Total Harmonic Distortion (THD) of less than 10% meaning it will not interfere with television or radio equipment.
  • Silent Operation
    The GC Series Digital Ballast has no noisy internal fans and is completely silent in operation.
