Grower’s Choice is proud to introduce their first 1000 watt Ultra High Frequency digital double ended fixture designed specifically for commercial applications.

It utilizes advanced Ultra High frequency technology and high output 1000 watt double ended High Pressure Sodium grow lamp. The GC-1000 delivers high-efficiency and the highest PAR available in the horticultural industry. It is also dimmable from 600 watts to 1100 watts.

Included 1000w DE HPS Lamp Options (choose one)


  • The Grower’s Choice 2K bulb is the optimal choice for blooming plants.
  • High concentrations of red and yellow light.
  • Mimics the natural color of sunlight.
  • 4000K

  • The Grower’s Choice 4K bulb is a slightly warmer metal halide, making it suitable for both flowering and vegetative growth.
  • Growers get the most use out of this style of bulb towards the end of the vegetative stage.
  • 6000K

  • The Grower’s Choice 6K bulb is the best bulb for plants in the vegetative stage.
  • Emits a cool blue light, matching the color of sunlight in spring time.
  • Encourages short inter-nodal spacing and bushy plants.
  • 10,000K

  • The Grower’s Choice 10K bulb is for growers who are looking to maximize yield and resin production.
  • Suitable for the last 7-14 days of flowering.
  • The 10K contains UV-B light, which is widely known to increase resin production.
  • Dimmable Option

    The GC-315 and GC-1000 Digital Ballasts allow lamps of various wattages to be operated in the same unit simply by adjusting the dial on the ballast. Each lamp will be operated to the exact specification that the lamp requires.

    Smart Step Technology

    By turning the dial on the GC Series Digital Ballast you can reduce the output of a lamp when not so much power is needed. Just turn the dial again to step back to full power.

    Super Lumen

    The Super Lumen feature on GC-315 and GC-1000 will increase the output of the ballasts highest wattage lamp to achieve maximum lamp performance. Increase is approximately 10% depending on model.

    Smart Start 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.

    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.

    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.
