The newly redesigned GC 630NS ceramic metal halide system boasts the famous Grower’s Choice Spectrum, that was horticulturally engineered to replicate and harness the forceful penetrating power of the sun.

This is the perfect fixture for all your horticulture applications and is leading the industry with the most efficient dimmable ballast and an open-air reflector that utilizes a unique passively cooled design.

The new GC-630NS offers ultimate control of spectral output with two horizontally placed lamps that allows the ability to mix spectra for an optimal full phase broad spectrum that allows all your specialty flowering plants to reach their maximum potential.

Grower's Choice 630 Watt CMH Kit Features

Smart Start™ 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.
