Introducing the MASTER PURSUIT series 500-watt CMH/CDM grow light system: 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 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 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.

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.

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.

The GC Series Digital Ballast is suitable for use with all high quality 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.

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'.

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.

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.

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.

The GC Series Digital Ballast has no noisy internal fans and is completely silent in operation.

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.


3K 500W Single Ended CMH

  • For use in any standard 500W CMH fixture
  • Produces more PAR per watt than HPS
  • Richest spectrum flowering lamp on the market with a CRI of 90
  • Optimal for flowering but can be used for Veg as well
  • Promotes higher rate of metabolic activity and resin production through the use of UV and far-red spectra

3K-R 315W Single Ended CMH

  • A slight increase in UV light to promote resin production
  • A taller peak in the Far-red to stimulate metabolic activity during flowering
  • Slightly higher PAR for better flower density
  • Increased intensity in red

4K 315W Single Ended CMH

  • Contains precision gasses for enhanced spectral output
  • Generates much less heat than HPS and MH
  • More closely matches sunlight than ANY other lighting solution available
  • Growers report tighter inter-nodal spacing and better yields on flowering plants

10K 315W MH Finishing Lamp

  • For use in 315w CMH fixtures
  • Strong UV peaks for increased resin production
  • Can be used for 25+ flower cycles before replacement
  • Use only in the last 7-14 days of flowering
  • Durable quartz glass arc tube ensures long usable life

Available with GROWER'S CHOICE Master Controller:

Grower’s Choice digital lighting controller enables the grower to control up to 200 fixtures. This dual-channel controller allows daisy chaining up to 100 fixtures per zone. En-abling complete control of your growing environment with timed on/off switching, sunrise/sunset, and precise temperature readings with dual thermal probes and thermal-threshold auto dim-shutdown for additional protection.
