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.

AI 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 main 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 breaker 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.
