Product Description

Adjusta-Watt 600w Digital Ballast - Dimmable.

The Adjusta-Watt 600 watt Digital Ballast is a software controlled dimmable digital ballast, designed to offer indoor gardeners the ultimate in versatility and performance from a single lighting system.

This high quality digital ballast allows you to:

    Operate bulbs of various outputs by adjusting the ballast for your selected bulb
    You can use Metal Halide or HPS bulbs (250/400/600 watt)
    Decrease bulb output when lower power is required
    Boost bulb output when maximum power is required

Adjusta-Watt Digital Ballast Features

The Adjusta-Watt 600 watt Digital Ballast will operate either 250 watt, 400 watt or 600 watt bulbs. Each bulb will run to the exact specification that each bulb needs.

Smart Step Technology

Adjust the dial on the Adjust-Watt Digital Ballast to reduce the output of a bulb when less power is required. Simply turn the dial again to step back up to maximum power.


The Over-Drive feature increases output of the ballasts highest wattage bulb by up to 10%.

Smart Start Ignition Control

This feature is unique to Adjusta-Watt ballasts. It makes the Adjusta-Watt Digital Ballast the safest and most reliable ballast when used with multiple automated bulb systems. When connecting multiple ballasts to the same mains circuit, the ignition control software will balance the electricity drawn by igniting one bulb at a time to prevent surges and spikes of electricity that could overload the mains circuit. To offer maximum efficiency this feature works together with the Soft Start Technology feature.

Soft Start Technology

This feature prolongs the life of bulbs by preventing current surge to the bulb and stopping any overload. Whenever the Adjusta-Watt is started from cold, there will be a 3 second delay prior to bulb ignition. After bulb ignition there wil be a series of 1 or 2 second delays before reaching full brightness after 3 to 5 minutes. Soft Start Technology is also active when decreasing or increasing power to the bulb using the Smart Step Ignition Control feature.

Restart of Heated Bulb after Mains Failure

To prevent the Adjusta-Watt ballast from restarting a hot bulb after power failure a 'timed restart system' is used. When a hot bulb is detected the restart will be delayed for 60 second intervals until the hot bulb has cooled adequately. Restart is then controlled by Smart Start Ignition Control and Soft Start Technology software.

Bulb Compatibility

All Adjusta-Watt Digital Ballasts are suitable for use with Sodium, Metal Halide and Dual Spectrum bulbs.

Automatic Frequency Adjustment

To prevent any type of bulb flicker, the Adjusta-Watt Digital Ballast will automatically adjust the output frequency to maintain a constant output regardless of power fluctuations or ageing bulbs.

Intelligent Circuit Protection

The Adjusta-Watt Digital Ballasts use a software controlled circuit breaking system that is not available with other digital ballasts. This system protects the ballast from a range of faults. These include: Open Circuit Protection, Short Circuit Protection, Over Voltage Protection, Under Voltage Protection and Over Temperature Protection. When the ballast is activated, it will caryy out a 3 second check of the circuit and if there is a fault, the ballast will go into a protection mode so as to not damage the ballast or the bulb.

Operating Temperature

The unique casing design of the Adjusta-Watt Digital Ballasts acts as a highly effective heat sink. This makes the ballast run cool without the need for any internal fans.

Radio Frequency Shielding

Adjusta-Watt Digital Ballasts operate with superior RF Shielding with Total Harmonic Distortion (THD) of less than 7%. This means it cannot interfere with other radio or television equipment.

Silent Operation

The Adjusta-Watt Digital Ballast does not operate with any noisy internal fans and runs completely silently.

Highly Energy Efficient

Adjusta-Watt Digital Ballasts are up to 30% more efficient than magnetic ballasts. Adjusta-Watt Digital Ballasts produce more lumens of light per watt of energy consumed. This efficiency does not diminish throughout the entire life of the ballast.

Compatible With:


Caution! Restarting a hot bulb can shorten the bulbs life or cause it to fail. Always allow hot bulbs and ballasts to cool before restarting.
