The Master Pursuit line utilizes an updated horizontal case to reflector design which accommodates more canopy space. This new case design is reinforced to protect the fixtures internal components and employs heat sinks with greater surface area, translating to better heat distribution, providing further protection, longer fixture life and better efficiency performance.

  • Clips: Improved ceramic lamp clips keep lamps secure, last longer than plastic clips and redistribute heat better.
  • Lamp Catch: Innovative safety device prevents damage due to dislodged or improperly installed lamps.
  • LevelIntegrated bubble level provides a visual reference to verify horizontal mounting consistency.
  • Reflector: Redesigned reflector provides greater heat redistribution, improves cross lighting and PPFD.
  • Cords: Uses quality hard wired power cords with M25 connectors provide IP65 water resistance.
  • Dual Ports: Two receptacles for the master controller eliminate the need for split devices or adapters.

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 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 ageing 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.
