Smart Start Ignition Control

This feature, which is unique to Grower's Choice products, makes this ballast safer and more reliable than other ballasts when used in automated multiple lamp applications. This feature is used when multiple units are connected to the same mains circuit. Integrated Ignition Control software balances the electrical draw by igniting one lamp at a time. This prevents electrical surges and spikes that might otherwise overload the mains circuit and trip circuit breakers. This feature is activated along with 'Soft Start Technology', which adds additional safety.

Soft Start Technology

This ballast prolongs lamp life by using Soft Start Technology. This technology involves stopping current rush to the lamp, which helps prevent lamp overload. There will be a 3 second fixed delay before ignition when the ballast is started. After achieving ignition, there is a series of random and short delays before maximum brightness is achieved. This takes approximately 3-5 minutes. SoftStart Technology is also used when increasing or decreasing power while using the 'Smart-Step' feature.

Re-Strike of Hot Lamp after Mains Failure

This Grower's Choice Horticultural Lighting Ballast uses a timed restrike system. This prevents the ballast from restriking a hot lamp just after a power failure. When a hot lamp is detected, the restrike will be delayed until the lamp has cooled enough to be re-ignited. In these situations the lamp temperature is rechecked every 60 seconds. 'SmartStart Ignition Control' and 'Soft Start Technology' software takes care of the re-ignition once the lamp temperature is cool enough.

Lamp Compatibility

This Grower’s Choice Horticultural Lighting Ballast is compatible with all high quality HPS, Metal Halide and Ceramic Metal Halide lamps. For best results is is recommended to use Grower’s Choice horticultural lamps. GC lamps are optimized for use with high efficiency digital ballasts that have adjustable output.

High Energy Efficiency

This Grower's Choice Horticultural Lighting Ballast is up to 30% more efficient than other magnetic ballasts. This ballast produces more lumens of light per watt of consumed energy. This efficiency is maintained for the entire life of the unit.

3 Years Warranty

Grower’s Choice USA warrants the mechanical and electronic components of their product to 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.

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

This Grower's Choice Horticultural Lighting Ballast exploits a smart software controlled circuit breaker system that is not available in other manufacturer's ballasts. This system protects against several possible problems including protection from: Short Circuits, Open Circuits, Over Voltage, Under Voltage, and Over Temperature. This ballast performs a 3 second circuit test at the time of ignition. If there is a fault, this ballast will go into a protection mode which protects the ballast and lamp from damage.

Running Temperature

The GC Series Digital Ballasts' case design is an excellent heat sink. This allows the ballast to stay cool without the need for internal fans.

RF Shielding

Ths Grower's Choice Horticultural Lighting Ballast has excellent RF Shielding. It’s Total Harmonic Distortion (THD) is less than 10%. This means it will not interfere with tv or radio equipment.

Silent Operation

The Grower's Choice Horticultural Lighting Ballast doesn’t have any loud internal fans. It’s operation is entirely silent.
