Experience High-Quality Growth with Hi-Par Digital Ballasts

Hi-PAR digital ballasts are designed for incredibly high performance in both hobby and commercial horticultural sectors. These ballasts use premium Japanese capacitors and are built tough for lasting durability. Hi-PAR ballasts provide the latest advances in digital technology to safely and reliably ignite HID bulbs while minimising harmonic distortion and attenuation.

Features and Benefits

  • High CRI: Increases essential oil and plant profile development, resulting in higher yields
  • Greater PAR/PBAR: Produces more usable light per watt than traditional HPS or magnetic ballasts
  • Soft Ignition and Random Start: Prevents electrical overloads, improves operational safety, and extends lamp life
  • Smart Ignition Software: Identifies the lamp type and fires the lamp with optimised ignition and operating currents
  • Compatible with Multiple Lamp Types: Works with HID, HPS, MH, SE or DE lamps, and 240v or 400v lamps

How to Use

  1. Choose the appropriate Hi-PAR digital ballast based on your specific lighting needs (315W, 600W, or 1000W).
  2. Mount the ballast securely to a wall or stable surface to prevent it from falling or shifting during operation.
  3. Connect the ballast to the appropriate lamp type (HPS, MH, SE or DE) using the included E40 adaptor (for 315W version) or other wiring as needed.
  4. Plug the ballast into a 220-240v electrical outlet and follow the manufacturer's instructions for safely igniting the lamp and controlling dimming if applicable for the chosen ballast model.

Aqua Gardening Suggests These are Best For

Hi-PAR digital ballasts are best suited for serious horticultural enthusiasts and commercial growers in search of high-quality lighting solutions that maximise plant growth and essential oil production. These ballasts are ideal for those using CMH, QMH, HPS, and MH lamps and seeking improved energy efficiency and enhanced performance over traditional magnetic ballasts.

Notes from Aqua Gardening

  • Ensure the ballast is mounted securely and properly connected to the appropriate lamp type before use.
  • Do not attempt to modify the ballast or force it to operate with incompatible lamps, as this may cause damage or create a safety hazard.
  • Always follow the manufacturer's guidelines for safe use and maintenance of the ballast and associated lighting equipment.


What makes Hi-PAR digital ballasts so reliable and high-performing?

Hi-PAR digital ballasts are built with premium Japanese capacitors rated for 10+ years of continual use. They also use digital soft start-up automation to safely and efficiently ignite HID bulbs with minimal harmonic distortion and attenuation. Additionally, Hi-PAR ballasts contain smart recognition software to prevent hot-lamp restrike and display error messages if issues are detected with the bulb or reflector.

What are the benefits of using a Hi-PAR 315W 400V Digital Ballast?

The Hi-PAR 315W 400V Digital Ballast offers higher CRI, leading to increased essential oil and plant profile development. It provides more usable PAR/PBAR light per watt compared to traditional HPS and has soft-ignition and light attenuation features that improve operational safety and extend lamp life.

Can the Hi-PAR 600W 400V Digital Ballast operate both HPS and MH lamps?

Yes, the Hi-PAR 600W 400V Digital Ballast is designed to operate any HID/HPS/MH 240v or 400v lamp. It also includes smart-ignition software that identifies the lamp type and fires it with optimized ignition and operating currents.

What is the main advantage of using a Hi-PAR 1000W 400V Digital Ballast?

The Hi-PAR 1000W 400V Digital Ballast is the most powerful HID workhorse in the Hi-PAR lineup. It is designed for use with DE (Double-Ended) 400v EL Lamps and maximises yield and efficiency for commercial horticultural lighting solutions when used with high-quality 1000W DE HPS lamps. This ballast also features soft-ignition and random start technology for improved safety and extended lamp life.

Will a Hi-PAR digital ballast work with double-ended lamps?

The Hi-PAR 600W and 1000W 400V Digital Ballasts are designed to be compatible with double-ended lamps, offering the flexibility to work with various types of horticultural lighting.

Is the E40 adaptor included with the Hi-PAR 315W 400V Digital Ballast?

Yes, an E40 adaptor is included in the box with the Hi-PAR 315W 400V Digital Ballast.
