The Grower’s Choice GC-630NS CMH Grow Light’s industry-leading, hyper-efficient dimmable ballast and open-air reflector built on an innovative, passively cooled design makes it the ideal grow light for indoor grows and gardens of any size. The GC-630NS offers you complete control of spectral output with two horizontally placed lamps that allow you to mix spectrums for the best full phase broad spectrum available so your flowering plants can achieve maximum health, yields, and potency.
This groundbreaking feature from Grower’s Choice makes the GC Series Digital Ballast the most reliable and safest ballast for multiple automated lamp applications. Connect multiple lights to the same main circuit and the integrated Ignition Control software will totally balance the unit’s electrical draw by igniting one lamp at a time to prevent electrical surges and spikes – so no more overloaded main circuits and tripped circuit breakers. This feature is activated along with Grower’s Choice’s “Soft Start Technology” for additional efficiency.
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.
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'.
Grower’s Choice’s innovative “Soft Start Technology” can extend the life of your grow light by preventing current from rushing to the light to mitigate lamp overload. When the light’s ballast starts from cold, “Soft Start” will create a 3 second delay before ignition, then it will create a series of random 0-2 second delays before the light’s full brightness is reached after about 3-5 minutes. SoftStart Technology will also be triggered power to the light is increased or decreased using the 'Smart-Step' feature.
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.
The GC Series Digital Ballast can be used with any high-quality HPS, Metal Halide or Ceramic Metal Halide lamps. To ensure a perfect match and optimal results, we recommend Grower’s Choice horticultural lamps. Grower’s Choice lamps are engineered to 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. 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.
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 throughout the lifetime of the unit.
