The Adjusta-Watt Digital Ballast is not like any ordinary 'dimmable' ballast. This variable output ballast has been specially designed to give the most selective growers the ultimate versatility and performance from a single lighting system. This super cool, super efficient, fully adjustable digital ballast will run 600w, 400w and 250w sodium, metal halide, and duel spectrum lamps and features an Over-Drive facility that increases the ballasts output for maximum performance from your lamps.

This Digital Ballast can be used in three different ways:

You select the lamp type and wattage and the ballast will run the lamp to the exact specification that the lamp requires, just as if the ballast was dedicated to that lamp. It's like having three separate ballasts in one unit!

You can reduce the output of your lamp when not so much power is needed. For example, if you are running a 600w lamp you can reduce the output to 400w or 250w. If you are running a 1000W lamp you can reduce to 600W and 400W.

You can boost the output of your lamp using the Over-Drive feature. This feature allows the output of the ballasts highest rated lamp (600w) to be increased by approximately 6% delivering maximum performance from the lamp.


Adjusta-Watt: The Adjusta-Watt Digital Ballast allows lamps of various wattages to be operated in the same unit simply by adjusting the dial on the ballast. The 600W model will run 250w, 400w and 600w lamps. Each lamp will be operated to the exact specification that the lamp requires. The 1000W will run at 400W, 600W and 1000W lamps.

Smart-Step Technology: By turning the dial on the Adjusta-Watt Digital Ballast you can reduce the output of a lamp when not so much power is needed. For example, if you are running a 600w lamp you can reduce the output to 400w or 250w and the lamp will operate exactly as if it were the lower wattage lamp. Just turn the dial again to step back to full power.

Over-Drive: The Over-Drive feature will increase the output of the ballasts highest wattage lamp to achieve maximum performance. Increase is approximately 6%

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 the lamp ignites there will be a series of random 0-2 second delays before full brightness is reached after approximately 3-5 minutes. The Soft Start Technology is also activated when increasing or decreasing power using the 'Smart-Step' feature.

Lamp Compatibility: The Adjusta-Watt Digital Ballast is suitable for use with Sodium, Metal Halide and Dual Spectrum lamps.

Automatic Frequency Adjustment: The Ajusta-Watt Digital Ballast automatically adjusts its output frequency to maintain a constant output regardless of input power fluctuations and ageing lamps. This frequency adjustment also prevents 'lamp flicker'.

Full Circuit Protection: The Adjusta-Watt Digital Ballast is fitted with a sophisticated built in circuit breaker system that protects the ballast against a series of faults including: Open Circuit Protection, Short Circuit Protection, Over Voltage Protection, Under Voltage Protection and Over Temperature Protection. In the event of a fault the ballast will go into protection mode to avoid damage to the ballast.

Running Temperature: The Adjusta-Watt Digital Ballast is extremely cool running making it easier to control working temperatures inside the grow room.

RF Shielding: The Adjusta-Watt Digital Ballast has superior RF Shielding with Total Harmonic Distortion (THD) of less than 7% meaning it will not interfere with television or radio equipment.

Silent Operation: The Adjusta-Watt Digital Ballast has no noisy internal fans and is completely silent in operation.

High Efficiency: The Adjusta-Watt Digital Ballast is up to 30% more efficient than a 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.

Re-Strike of Hot Lamps: In the event of a power failure, The Adjusta-Watt uses a timed re-strike system that will detect hot lamps before re-striking. If hot lamps are detected re-strike will be delayed for 60 second intervals until lamps have cooled sufficiently to be re-ignited.

Low Amps: Low Amps on start up means more ballasts can be run on the mains circuit than with magnetic ballasts.
