A new milestone in CMH technology, the Master Pursuit 500w CMH all-in-one fixture is a must-have.

With higher efficiency than traditional 315w lamps, the 65% increase in light energy is a more economical alternative that has nearly the same output as two 315w CMH lamps used in the 630w CMH fixtures.

Providing an average of 1000 umol/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.

You can cater to your plants’ specific needs by choosing from one of 4 different spectrum lamps:

  • 500w 3K: ideal for flowering, but work for vegging also
  • 500w 3K-R: enhanced version of the 3K for increased resin production
  • 500w 4K: closest bulb to natural sunlight; great for all growth stages
  • 500w 10K: use during final 7-14 days of flowering for increased resin production

Master Pursuit 500 Watt CMH Kit Features

  • Rated Main Voltage: 120V, 208V, 240V, 277V
  • Input Current: 4.7A, 2.7A, 2.4A, 2.1A
  • Input Frequency: 50/60 Hz
  • Power Factor: >0.98
  • THD: <10%
  • Required Lamp Voltage: 110V ~ 140V
  • Illumination Surface: Indoor 4' X 4', Green house 6' X 6'

AI Ignition Control

This revolutionary feature, unique to Grower's Choice products, makes GC Series Digital Ballasts the safest and most reliable ballasts when used in automated multiple lamp applications.

When multiple units are connected to the same mains circuit, the 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 their '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. Soft Start 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, because they 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.

3 Year Warranty

Grower’s Choice USA warrants the mechanical and electronic components of the ballast and reflector be free of defects in material and workmanship if used under normal operating conditions for a period of three (3) years from the original date of purchase. The bulbs are under a one (1) year warranty.

Kit Includes

  • Fixture with the one set of power cord attached.
